Level of Repair Harddisk BadSector

2010-10-02T04:39:00.001-07:00

The hard disk is where the operating system and all computer programs are stored. Due to this, a correctly working drive is important in the operation of any PC.

But since these drives are essentially merely an electro-mechanical devices, and like every other machine they can at last breakdown and fail. And then oops, without backups, all of your family footage, legal documents and critical emails are gone!

There are 3 (three ) levels of file recovery for a dying or damaged drive :

1. Basic Level : The drive is working ( your can hear it spin up but it won’t boot to Windows ) This typically suggests that some necessary Windows files have been comprised or damaged in some shape. You’ve got to choices…

Use a Rescue CD : You can grab a bootable CD with hard drive utility software already installed on it. You can then make repairs or copy your files from your bad drive to a replacement. A good big name brand rescue CD for Windows is the “Ultimate Boot CD”.

Move the Drive : if you do not have a technique of burning a rescue CD and do not desire to hang about for a copy to sent to you ; you can always move your bad drive and place it in another working desktop Computer .

2. Intermediate Level : The drive works but you can not see the files you would like using the strategies above. You at about that point have to get out the massive guns. You’ll have to download and run an data recovery program like “Active UNDELTE”, “Recover My Files”, and so on. Both these programs are strong, trustworthy, and simple to use and won’t cost an arm or a leg to purchase. Both have tech support options if you want further help.

3. Advanced Level : You have attempted everything above but you can not find that Last Will from Aunt Sue…

At that point you have likely spent a couple of hours ( if not days ) without your Computer and invested just over a $100 in software if you used all the above products. Now, is the time for you to choose to either employ a pro level recovery application or chuck in the towel and take your drive to a recovery expert.

If you’ve got the time but not a great deal of money ( understand that tough drive recovery services can cost hundreds or thousands of greenbacks ) then you can ratchet it up a bit and purchase a copy of the home version of EasyRecovery from Ontrack. Ontrack is one of the leading information recovery corporations in the world.

But if time is more urgent and cash is no obstruction then bite the bullet and take your drive to a local PC shop that does recovery work. Or if that’s not possible then contact a giant service like Ontrack and ship your drive to them. Data recovery can be costly irrespective of who does it, so to be on the safe side and make file backups often and completely.

5 Network Topology

2010-05-15T08:40:00.001-07:00

Computer network topologies can be categorized in the following categories.

Hybrid networks are the complex networks, which can be built of two or more above mentioned topologies.

Bus Topology

Bus topology uses a common backbone to connect all the network devices in a network in a linear shape. A single cable functions as the shared communication medium for all the devices attached with this cable with an interface connector. The device, which wants to communicate send the broadcast message to all the devices attached with the shared cable but only the intended recipient actually accepts and process that message.

Ethernet bus topologies are easy to install and don’t require much cabling and only a main shared cable is used for network communication. 10Base-2 and 10BaseT are two popular types of the Ethernet cables used in the Bus topology. Also, Bus network works with very limited devices. Performance issues are likely to occur in the Bus topology if more than 12-15 computers are added in a Bus Network. Additionally, if the Backbone cable fails then all network becomes useless and no communication fails among all the computers. Unlike in the Star topology in which if one computer is detached from a network then there is not effect on the other computers in a network.

Ring Topology

In ring Network, every computer or devices has two adjacent neighbors for communication. In a ring network, all the communication messages travel in the same directory whether clockwise or anti clockwise. Any damage of the cable of any cable or device can result in the breakdown of the whole network. Ring topology now has become almost obsolete.
FDDI, SONET or Token Ring Technology can be used to implement Ring Technology. Ring topologies can be found in office, school or small buildings.

Star Topology

In the computer networking world the most commonly used topology in LAN is the star topology. Star topologies can be implemented in home, offices or even in a building. All the computers in the star topologies are connected to central devices like hub, switch or router. The functionality of all these devices is different. I have covered the detail of each networking devices in the separate portion of my website. Computers in a network are usually connected with the hub, switch or router with the Unshielded Twisted Pair (UTP) or Shielded Twisted Pair Cables.

As compared to the bus topology, a star network requires more devices & cables to complete anetwork. The failure of each node or cable in a star network, won’t take down the entire network

as compared to the Bus topology.

However if the central connecting devices such as hub, switch or router fails due to any reason,then ultimately all the network can come down or collapse.

Tree Topology

Tree topologies are comprised of the multiple star topologies on a bus. Tree topologies integrate multiple star topologies together onto a bus. Only the hub devices can connect directly with the tree bus and each Hub functions as a root of a tree of the network devices. This bus/star/hybrid combination supports future expandability of the computer networks, much better than a bus or star.

Mesh Topology

Mesh topology work on the concept of routes. In Mesh topology, message sent to the destination can take any possible shortest, easiest route to reach its destination. In the previous topologies star and bus, messages are usually broadcasted to every computer, especially in bus topology. Similarly in the Ring topology message can travel in only one direction i.e clockwise or anticlockwise. Internet employs the Mesh topology and the message finds its route for its destination. Router works in find the routes for the messages and in reaching them to their destinations.The topology in which every devices connects to every other device is called a full Mesh topology unlike in the partial mesh in which every device is indirectly connected to the other devices.

note

Topologies are the important part of the network design theory. A better network can be built if you have the knowledge of these topologies and if you know the difference between each topology.

Wireless Network Type

2010-05-15T07:26:00.001-07:00

Wireless Network Types

1. Wireless Local Area Networks (WLANS)

WLANS allow users in local area, such as in a university or a library to form a network and gain wireless access to the internet. A temporary network can be formed by a small number of users without the need of access point; given that they do not need to access the resources.

2. Wireless Personal Area Networks (WPANS)

There are two current technologies for wireless personal network Bluetooth and Infra Red. These technologies will allow the connectivity of personal devices within an area of 30 feet. Infra Red requires a direct line and the range is less as compared to Bluetooth technology.

3. Wireless Metropolitan Area Networks (WMANS)

WMANS allow the connectivity of multiple networks in a metropolitan area such as building in a city. The network connectivity is the alternative of copper or fiber cabling.

4. Wireless Wide Area Networks (WWANS)

WWANS or Wireless Area Networks can be maintained over large areas such as in different cities or between different countries, via multiple satellite systems or antenna sites. The types of system are called 2G systems.
The following table shows the range those different types of wireless network covers.
Network Meter
Personal Area Network       0 - 10
Local Area Network              0 - 100
Wide Are Network                 0 - 10000
Security in Wireless Networking
The following different types of security methods are available in the wireless networking.

5. Wired Equivalent Privacy (WEP)

Wired Equivalent Privacy is intended to stop the interference of radio frequency that is signaled by unauthorized users and this security measure is most suitable for the small networks. There is not key management protocol and each key is entered manually into the clients that’s why this is very time consuming administrative task. The WEP security method is based on the RC4 encryption algorithm. In the WEP all the client computers and Access points are configured with the same encryption and decryption keys.

Service Set Identifier (SSID)

Service Set Identifier (SSID) acts a simple password by allowing WLAN network to be split up into different networks and each having a unique identifier. These identifiers are configured in the multiple access points. To access any of any networks, a computer is configured in such a way that each is having a corresponding SSID identifier for that network. If the SSID match between the two computers or networks then access is granted to each other.

Media Access Control filtering (MAC Access Control)

A list of the MAC addresses of the client computers can be inputted into an Access point and only those computers are granted to give the access to the network. When a computer makes a request, its MAC address is compared to the list of the MAC addresses to the Access point and based on this access permission granted to deny.
This is a good security method but it is mainly involved in the small wireless networks because there is more manual work is involved of entering the MAC address into the Access point.

Bluetooth

Bluetooth is a simple type of the wireless networking that operates in the digital devices, like mobiles phones, personal computers, PDA, Laptops, digital camera, MP3 players and other Bluetooth enabled devices to form a small network. In the Bluetooth technology eight devices can be connected to each other at the same time. Bluetooth can also be found in the headsets, hands-free kits, wireless keyboards and mouse. Bluetooth technology was invented by Ericsson in 1994 and after four years in 1998 some major mobile phone companies such as Nokia, Ericsson, Intel and Toshiba formed a group to promote this technology.

Bluetooth technology falls in the category of personal area networking because it operates in the range of 30 to 300 feet. Bluetooth uses the radio waves technology, which is not very expensive and has low power consumption. Many different companies are intended to add the Bluetooth chip in their digital devices. Bluetooth technology is getting very popularity because of its low cost and portability.

The Future of Wireless Networking

WLANS wireless networking type is very popular in home networking and more than 20 percent homes with broadband internet are using WLANS and this number is increasing. In a general estimate worldwide hotspots have now reached more than 30,000 and will grow about 210,000 in the next few years. Most large hotels already offer Wi-Fi and the business travelers are willing to pay wireless access. 802.11 is the next Wi-Fi speed standard is set to offer bandwidth around 108Mbps and is still under development. With the speed of 70 Mbps and a range up to 30 miles, the 80216 standard, known as WiMAX is sure to get boost.

Tips & Tricks

• When purchasing a wireless NIC card try to get one that is having external antenna. When you are out and using Wi-Fi enabled laptop, disable Microsoft file and sharing, which enables other computers in a network to access data and resources on your computer. In this way, your computer or laptop will be saved from hackers.
• If you are concerned about the interference from the other wireless access point set the AP and wireless computers to use a non-overlapping channel.
• Change the configuration interface password of the access point before you enable it.
• Only buy an access point that is having upgradeable capabilities. By this way you can take the advantage of security enhancements.
• Keep the access point up to date.

Compress and decompress by KGB ARCHIVER

2010-05-14T11:24:00.001-07:00

KGB Archiver is is the compression tool with unbelievable high compression rate. It surpasses even such efficient compression tool like 7zip and UHARC in terms of the abilities. Unfortunately although its powerful compression rate, it has high hardware requirements (I recommend processor with 1,5GHz clock and 256MB of RAM as an essential minimum). One of the advantages of KGB Archiver is also AES-256 encryption which is used to encrypt the archives. This is one of the strongest encryptions known for human.

   1. Open the KGB Archiver program.
   2. Choose Compress files from the options and click Next >.
   3. On the next window, you can change the directory location where you want to put the file, give a name to your new archive and add file(s) or directory. Press the Next > button when you finish.
   4. The program will then create the archive file for you and show a dialog box with some information when it has finish.

Extract a zip file

KGB Archiver 2

   1. Open the KGB Archiver program.
   2. Choose Decompress files from the options and click Next >.
   3. On the next window, choose your archive file and directory location where you want to put the file(s). You can extract all files on the archive by unchecking the Choose files to decompress option or extract selected file by checking the option and select the file(s).

Tips Facebook

2010-03-23T12:46:00.000-07:00

Below is a listing of our top 10 tips for the popular social networking website Facebook. Hide users, games, polls, etc. It quickly gets annoying seeing some users posts, game invites, polls, etc. Hovering your mouse to the right of the post and clicking the Hide button as shown below can hide any post. Once this button is pressed you'll be prompted with the option to hide that user or in the case of a Facebook application the option to hide that application from ever showing up on your profile. To unhide someone or unblock an application click the Edit Options link in the bottom right corner of the news feed as shown below. Greasemonkey and FB Purity Although Facebook does not allow the ability to hide friends getting new friends messages, friends becoming fans of something, and some application messages they can still be hidden with browser add-ons. If you're running Mozilla Firefox, Chrome, Opera, or Safari we suggest installing the Facebook Purity add-on. Facebook lite In addition to all the tips mentioned above if the main Facebook page is still too much for you consider using Facebook lite, which is found at: http://lite.facebook.com/ Update your privacy settings Click Account in the top right corner of the Facebook window and then click Privacy settings to adjust who is capable of seeing what on your Facebook profile. We highly recommend going through all the privacy settings to verify your privacy is properly protected. Anything that is not set to friends only or friends of friends can be seen by anyone searching on the Internet. Use the Facebook top bar for navigation Knowing how to properly navigate is vital if you want to get the most out of Facebook. Below is a brief description of each of the available options in the top bar as shown above. Home (facebook logo) - Clicking this logo will take you to your wall (News Feed) that shows all friends recent posts. Friend requests - If any friend requests are waiting to be approved this icon will show a notification of how many friends are waiting for approval. This icon can also be clicked when you want to view any friend recommendations or search for friends on Facebook. Messages - This section allows you to send and receive private messages between one or more people you're friends with. Notifications - Any time a friend or Facebook application creates a new post you'll be notified in this section. Clicking this icon will show all recent notifications. If you wish to change what is capable of sending you notifications including any Facebook applications or games click the See All Notifications link at the bottom and check or uncheck what you want to be notified on. Search - Finally, the search box in Facebook can be a powerful tool that can be used to quickly find any current friends or people on Facebook. In addition searching for terms such as a company name, product, sports team, music band, etc. will find fan pages and groups that can be joined. Modify your account notifications Keep your e-mail and/or your cell phone clean by updating or eliminate Facebook notifications or keep more up-to-date by adding new notifications. Facebook notifications can be added and removed by clicking Account link in the top right corner, then Account Settings, and then clicking the Notifications tab. Top News and Most Recent By default Facebook will display your wall postings in the News format, which means it only displays posts it believes are most relevant to you. These results are based on your past interaction with your friends. If you want to see every post made by all your friends that are not hidden click the Most recent link in the upper right section of your news feed as shown in the above picture example. If you want to adjust who shows up manually click the Edit Options in the bottom right corner of your news feed. View High School work friends If you've added your High School and/or previous Work locations to your profile, quickly see all classmates and co-workers on Facebook by clicking the link in your Info tab under your profile. Quickly change profile picture Your profile picture can be quickly changed to any other picture by visiting your profile, hovering the mouse over your current profile picture, and clicking the Change Picture link that appears in the top right corner of the picture. Don't post private information on friend's walls on in comments When you make a post on a friend's wall or in any of their comments realize that any of their friends are going to be able to see that post. If you wish for something to remain only between you and a friend send them a Facebook message instead. Suggestions and random friend invites As you get more friends on Facebook it will begin making friend, groups, and fan suggestions. These are suggestions made by Facebook and not your friends. Unless these are something you're interested in they can be ignored. This same rule can be applied to people who may want to be your friend that you don't know. If you don't know someone don't accept his or her friend invite. Once someone becomes your friend they'll have access to any information your friends are capable of seeing. Tag your Facebook friends in your photos Always make sure to tag any of your Facebook friends that are in pictures you upload. However, never tag someone who is not in the picture. When someone is tagged in a photo that picture is automatically added to that persons profile and is a great way to share pictures with all friends.

Procedure update Bios

2009-09-04T06:17:00.001-07:00

All latest Motherboards today, 486/ Pentium / Pentium Pro etc.,ensure that upgrades are easily obtained by incorporating the system BIOS in a FLASH Memory component. With FLASH BIOS, there is no need to replace an EPROM component. Once downloaded, the upgrade utility fits on a floppy disc allowing the user to save, verify and update the system BIOS. A hard drive or a network drive can also be used to run the newer upgrade utilities. However, memory managers can not be installed while upgrading.

Most pre-Pentium motherboards do not have a Flash BIOS. The following instructions therefore do not apply to these boards. If your motherboard does not have a Flash BIOS (EEPROM) you will need to use an EPROM programmer to re-program the BIOS chip. See your dealer for more information about this.

Please read the following instructions in full before starting a Flash BIOS upgrade:
A. Create a Bootable Floppy (in DOS)

•With a non-formatted disk, type the following:

format a:/s

•If using a formatted disk, type:

sys a:

This procedure will ensure a clean boot when you are flashing the new BIOS.

B. Download the BIOS file

•Download the correct BIOS file by clicking on the file name of the BIOS file you wish to download.

•Save the BIOS file and the Flash Utility file in the boot disk you have created. Unzip the BIOS file and the flash utility file. If you don't have an "unzip" utility, download the WinZip for Windows 95 shareware/ evaluation copy for that one time use from _www.winzip.com or _www.pkware.com. Most CD ROMs found in computer magazines, have a shareware version of WinZip on them.

•You should have extracted two files:

Flash BIOS utility eg: flash7265.exe (for example)

BIOS eg: 6152J900.bin (example)

Use the latest flash utility available unless otherwise specified (either on the BIOS update page or in the archive file). This information is usually provided.

C. Upgrade the System BIOS

During boot up, write down the old BIOS version because you will need to use it for the BIOS backup file name.

Place the bootable floppy disk containing the BIOS file and the Flash Utility in drive a, and reboot the system in MS-DOS, preferably Version 6.22

•At the A:> prompt, type the corresponding Flash BIOS utility and the BIOS file with its extension.

For example:

flash625 615j900.bin

•From the Flash Memory Writer menu, select "Y" to "Do you want to save BIOS?" if you want to save (back up) your current BIOS (strongly recommended), then type the name of your current BIOS and its extension after FILE NAME TO SAVE: eg: a:\613J900.bin

Alternatively select "N" if you don't want to save your current BIOS. Beware, though, that you won't be able to recover from a possible failure.

•Select "Y" to "Are you sure to program?"

•Wait until it displays "Message: Power Off or Reset the system"

Once the BIOS has been successfully loaded, remove the floppy disk and reboot the system. If you write to BIOS but cannot complete the procedure, do not switch off, because the computer will not be able to boo, and you will not be given another chance to flash. In this case leave your system on until you resolve the problem (flashing BIOS with old file is a possible solution, provided you've made a backup before)

Make sure the new BIOS version has been loaded properly by taking note of the BIOS identifier as the system is rebooting.

For AMI BIOS
Once the BIOS has been successfully loaded, remove the floppy disk and reboot the system holding the "END" key prior to power on until you enter CMOS setup. If you do not do this the first time booting up after upgrading the BIOS, the system will hang.

BIOS Update Tips
note:
1.Make sure never to turn off or reset your computer during the flash process. This will corrupt the BIOS data. We also recommend that you make a copy of your current BIOS on the bootable floppy so you can reflash it if you need to. (This option is not available when flashing an AMI BIOS).

2. If you have problems installing your new BIOS please check the following:

Have you done a clean boot?
In other words, did you follow the above procedure for making a bootable floppy? This ensures that when booting from "A" there are no device drivers on the diskette. Failing to do a clean boot is the most common cause for getting a "Memory Insufficient" error message when attempting to flash a BIOS.

If you have not used a bootable floppy, insure a clean boot either by

a) pressing F5 during bootup

b) by removing all device drivers on the CONFIG.SYS including the HIMEM.SYS. Do this by using the EDIT command.

Have you booted up under DOS?
Booting in Windows is another common cause for getting a "Memory Insufficient" error message when attempting to flash a BIOS. Make sure to boot up to DOS with a minimum set of drivers. Important: Booting in DOS does not mean selecting "Restart computer in MS-DOS Mode" from Windows98/95 shutdown menu or going to Prompt mode in WindowsNT, but rather following the above procedure (format a: /s and rebooting from a:\).

Have you entered the full file name of the flash utility and the BIOS plus its extension?
Do not forget that often you will need to add a drive letter (a:\) before flashing the BIOS. Example: when asked for file name of new BIOS file which is on your floppy disk, in case you're working from c:\ your will need to type a:\615j900.bin, rather than 615j900.bin only.

Are your passwords saved? Check up on suspicious sites, avoid Web forgeries and make sure a site is what it claims to be.

Private Browsing

new Sometimes it’s nice to go undercover. When this feature is enabled, you won’t leave a single browsing fingerprint behind for others to discover. You can slip in and out of private browsing mode quickly, so it’s easy to return to what you were doing before as if nothing ever happened (you can also browse privately all the time).

Forget This Site

new Having second thoughts about having visited a certain Web site? With this feature, you can remove every trace of that site from your browser—no questions asked!

Anti-Malware

improved Firefox protects you from viruses, worms, trojan horses and spyware. If you accidentally access an attack site, it will warn you away from the site and tell you why it isn’t safe to use. Firefox checks every part of a Web page before loading it to make sure nothing harmful is sneaking in the back door.

Anti-Phishing

Shop and do business safely on the Internet. Firefox gets a fresh update of web forgery sites 48 times in a day, so if you try to visit a fraudulent site that’s pretending to be a site you trust (like your bank), a browser message—big as life—will stop you.

Parental Controls

Enforce parental control settings you’ve entered on Vista—stop unwanted downloads and more.

Clear Recent History

improved Clear all your private data or just your activity over the past few hours with a few quick clicks. You have full control over what to delete, and then your info is gone for good—on your own computer or the one at your local library. It’s that easy.

Customized Security Settings

Control the level of scrutiny you’d like Firefox to give a site and enter exceptions—sites that don’t need the third degree. Customize settings for passwords, cookies, loading images and installing add-ons for a fully empowered Web experience.

Add-ons

Firefox looks for a secure connection before installing or updating add-ons, 3rd party software, and Personas.

Password Manager

We’ve seamlessly integrated this feature into your surfing experience. Choose to “remember” site passwords without intrusive pop-ups. Now you’ll see the “remember password” notification integrated into your view at the top of the site page.

Anti-Virus Software

Firefox integrates elegantly with your antivirus software. When you download a file, your computer’s antivirus program automatically checks it to protect you against viruses and other malware, which could otherwise attack your computer.

Pop-Up Blocker

Banish pop-ups (and pop-under windows) from your surfing experience once and for all. Or, find a happy medium—choose to view blocked pop-ups or create an “allow” list of sites whose pop-ups you’re okay with seeing.

Automated Update

Our open-source security strategy lets us find—and fix—security issues in record time, making Firefox the safest way to surf. Install upgrades when you receive automatic notification or wait until you’re ready.

Bypass Blocked Web

2009-07-17T11:00:00.001-07:00

BYpass WEB FILTERING

Did you had can access any web when you surfing …

Lets pretend for a moment that the Internet is made up of 26 websites, A-Z. The web filter blocks your browser from accessing sites X-Z, but not sites A-W. Simply make the browser think you’re going to A-W. There are a variety of ways to do this:

Proxy Servers:

This is a list of http proxies. These sites may not be up forever, so you may need to search for “free http proxy” or “public proxy servers” or other similar terms.

Proxy server lists:

http://www.aliveproxy.com
http://www.multiproxy.org
http://www.publicproxyservers.com/index.html
http://www.tehbox.com/proxy
http://www.proxz.com
http://www.proxy4free.com/index.html
http://free-proxies.com

Now that you have a list of proxies, you would open IE (internet explorer) and click on Tools > Internet Options > Connections > LAN Settings > Advanced. Enter the address and port of one of the servers from the list in the proper area (http) and make sure the “use a proxy server for your LAN” option is selected. Remember to replace the proxy and port at your terminal to the original when you're done.

*Note: Some proxies listed may not work, and this method may decrease your surfing speed. By trying various entries, you’ll find one that works, or works faster.

The infamous translation trick:

Go to a web page translation site and use their services to “translate a page to English” thus accessing the blocked page through their trusted site.

You’ll notice that several translation sites are blocked, but by using less popular ones, this method can still be effective. Here is a list of some translation services. Again, these sites may not be up forever, so you may need to search for them.

http://babelfish.altavista.com
http://world.altavista.com
http://translation.langenberg.com
http://freetranslation.com/web.thm

Url Scripting:

Url scripting is the easiest method. It works on a select few web filters and is based on the same principal as the translation trick. By typing and address like “www.yahoo.com@www.restricted_site.com the filter will not go into effect as it recognizes the trusted site (in this case yahoo.com)

Other tricks:

Simply open the command prompt and type:

Ping restricted.com ? restricted.com obviously being the restricted site

At this point you can take down the IP address (ex. 216.109.124.73) and enter it into the browser. If access to the command prompt is also restricted, see “How to bypass restrictions to get to the command prompt.” If this article has been taken from information leak, then know that it involves anything from opening the browser, selecting view > source, then saving it as X.bat and opening it to opening a folder or browser and typing in the location of cmd.exe depending on the OS. I will not go into further, as this a completely different topic.

Use https://restrictedsite.com as referring to it as a secured site may confuse the filter.

Note: These are ancient methods that many new filters defend against, but still may be applicable in your situation. If not, a little history never hurt anyone.

Web based Proxies:

Another one of the easier, yet effective methods include web based proxies. These are simple in the fact that you just enter the restricted address and surf! Some of these have some restrictions, like daily usage limits, etc but you can also use another proxy (perhaps one that sucks, like a text only) to bypass their restrictions as well. Here is a list of some:

Proxy Programs:

There are many proxy programs that allow you to surf anonymously that are more or less based on the same topics we’ve covered here. I’ve added them just to cover the topic thoroughly:

http://www.hotscripts.com/Detailed/28480.html
http://www.inetprivacy.com/a4proxy/anonymous-grc.htm
http://www.orangatango.com/home/index.ie.html
http://www.steganos.com
http://www.anonymization.net ?
toolbar that requires admin rights to install

Making your own CGI proxy server:

Making your own proxy server may come in handy, but I personally find that simply uploading a txt file/w a list of proxies to a free host makes for a much easier and headache free solution. If you don’t know PERL, there is code out there to help you set it up. Check out these sites for more info:

New Bios Attack renders AV useless

2009-06-26T03:26:00.001-07:00

Only solution may be physically removing Bios chip, say researchers

A new form of attack that installs a rootkit directly onto a computer's Bios system would render anti-virus software useless, researchers have warned.

Alfredo Ortego and Anibal Sacco of Core Security Technologies explained that the attack is possible against almost all types of common Bios systems in use today.

The researchers devised a 100-line Python script that could be flashed onto the Bios to install a rootkit. Because the Bios software activates before any other program on a computer when it starts up, normal anti-virus software would be unable to detect it.

"We tested the system on the most common types of Bios," said Ortega. "There is the possibility that newer types of Extensible Firmware Interface Bios may be resistant to the attack, but more testing is needed."

The attack is only possible if the attacker already has full administrative control of the target PC, but this is possible through a standard virus infection. Once that is achieved, the malware operator would be able to flash a rootkit directly onto the Bios.

Even if the initial virus was detected and removed, the computer would still be under remote control. A full wipe of the hard drive and complete reinstallation of the operating system would not remove it, the researchers warned.

If a sophisticated rootkit was put onto the Bios it could be even more difficult for an administrator to debug the system, according to Ivan Arce, chief technology officer at Core Security.

"You would need to reflash the Bios with a system that you know has not been tampered with," he said. "But if the rootkit is sophisticated enough it may be necessary to physically remove and replace the Bios chip."

The attack vector is also usable against virtual systems, the researchers said. The Bios in VMware is embedded as a module in main VMware executable, and thus could be altered.

However, it is possible to protect against this attack by locking down the Bios chip from flash updates, either physically or by password-protecting the system against unauthorised changes.

"The best approach is preventing the virus from flashing onto the Bios," said Sacco. "You need to prevent flashing of the bios, even if it means pulling out jumper on motherboard."

Step by step update Bios

2009-06-24T06:27:00.001-07:00

Following this instruction carefully !…

Type 486/ Pentium / Pentium Pro etc.,ensure that upgrades are easily obtained by incorporating the system BIOS in a FLASH Memory component.

Motherboard With FLASH BIOS, there is no need to replace an EPROM component. Once downloaded, the upgrade utility fits on a floppy disc allowing the user to save, verify and update the system BIOS. A hard drive or a network drive can also be used to run the newer upgrade utilities. However, memory managers can not be installed while upgrading.

Please read the following instructions in full before starting a Flash BIOS upgrade:
A. Create a Bootable Floppy (in DOS)

With a non-formatted disk, type the following:

format a:/s

If using a formatted disk, type:

sys a:

This procedure will ensure a clean boot when you are flashing the new BIOS.

B. Download the BIOS file

•Download the correct BIOS file by clicking on the file name of the BIOS file you wish to download.

•You should have extracted two files:

Flash BIOS utility eg: flash7265.exe (for example)

BIOS eg: 6152J900.bin (example)

Use the latest flash utility available unless otherwise specified (either on the BIOS update page or in the archive file). This information is usually provided.

C. Upgrade the System BIOS

During boot up, write down the old BIOS version because you will need to use it for the BIOS backup file name.

Place the bootable floppy disk containing the BIOS file and the Flash Utility in drive a, and reboot the system in MS-DOS, preferably Version 6.22

•At the A:> prompt, type the corresponding Flash BIOS utility and the BIOS file with its extension.

For example:

flash625 615j900.bin

Alternatively select "N" if you don't want to save your current BIOS. Beware, though, that you won't be able to recover from a possible failure.

Select "Y" to "Are you sure to program?"

Wait until it displays "Message: Power Off or Reset the system"

Make sure the new BIOS version has been loaded properly by taking note of the BIOS identifier as the system is rebooting.

For AMI BIOS
Once the BIOS has been successfully loaded, remove the floppy disk and reboot the system holding the "END" key prior to power on until you enter CMOS setup. If you do not do this the first time booting up after upgrading the BIOS, the system will hang.

BIOS Update Tips
note:
1. Make sure never to turn off or reset your computer during the flash process. This will corrupt the BIOS data. We also recommend that you make a copy of your current BIOS on the bootable floppy so you can reflash it if you need to. (This option is not available when flashing an AMI BIOS).

2. If you have problems installing your new BIOS please check the following:

If you have not used a bootable floppy, insure a clean boot either by

a) pressing F5 during bootup

b) by removing all device drivers on the CONFIG.SYS including the HIMEM.SYS. Do this by using the EDIT command.

Have you booted up under DOS?
Booting in Windows is another common cause for getting a "Memory Insufficient" error message when attempting to flash a BIOS. Make sure to boot up to DOS with a minimum set of drivers. Important: Booting in DOS does not mean selecting "Restart computer in MS-DOS Mode" from Windows 98/95 shutdown menu or going to Prompt mode in WindowsNT, but rather following the above procedure (format a: /s and rebooting from a:\).

c:\ your will need to type a:\615j900.bin, rather than 615j900.bin only.

SEOQUAKE to see DoFollow OR NOT

2009-05-12T07:58:00.001-07:00

If you want to know the other site what can make our site get backlink for get PR... I Think you must try this add-on for firefox... you can see who have BACKLINK or not... Yeah the name add ons is Seoquake you can download <="<">href="https://addons.mozilla.org/en-US/firefox/addon/3036" target="_blank">here Beginner web masters and seos will find SeoQuake useful for estimating effectiveness and competitive ability of their SEO efforts. In the hands of professional SeoQuake will become a powerful and indispensable tool for analyzing optimization and promotion level of internet web-projects. SeoQuake can be distinguished from similar projects by a wide range of parameters available for analysis, simplicity of use and also a tool for creation of custom parameters. SeoQuake consists of two functional parts. The first one is SeoBar. The second part is the computation of the parameters for search results and its inclusion into search engine result pages – SERPs – for the most popular search engines. SeoBar SeoBar can be described as an additional toolbar, which shows the values of selected parameters for the page currently opened in the browser window. Set of parameters shown by SeoBar is fully customizable by user. Inclusion of parameters in SERPs After submission of the query into the search engine user is presented with SERP with search results. SeoQuake shows values of the parameters for search results under each search result shown on SERP. Set of parameters shown is fully customizable by user. Loading of parameters can be handled in two different ways – simultaneously with the loading of the SERP or after SERP loading, by user demand. Ranking of the results by selected parameter in ascending/descending order and storing results in file are available features. Parameters While having a wide range of default parameters, SeoQuake also gives users the opportunity to create their own parameters and also group them into presets and switch between these presets on the fly, during the work. General set of parameters consists of such parameters as Google PR (Google PageRank of current page), Google Index (Number of indexed pages. Google version), Google link (Number of links, pointed to the current page. Google version (Except links from concerned domain)), similar parameters for many other search engines (Yahoo, MNS, Yandex, Rambler, Baidu) and some other miscellaneous parameters. There is also a tool for creation of custom parameters at user’s disposal. These parameters can be saved and used for future research, whatever it may be. All SeoQuake parameters can be turned on/off to be shown in SeoBar or on SERPs. Miscellaneous SeoQuake submits a query to search engine every time when it needs to obtain a value for a new parameter (that is not in a cache yet), defined by this search engine. Frequent use of big amount of the parameters may lead to the ban of user’s IP address from search engine. In this case, you will need to delete cookies or change proxy server. Full description of all SeoQuake functions and parameters can be found on official site of addon: http://www.seoquake.com/index-en.php Warning! Extension is using the advertisement block in results of search engines. Please, read Privacy Policy, before install http://www.seoquake.com/policy.html
