Corrupted Bios

Dell Inspiron 2200 notebook
November 10, 2009 at 13:50:05
Specs: Windows XP
My daughter got a root virus that corrupted and locked her bios. It will not recognize her hard drive or her optical drive. Therefore I can not boot windows or configure boot sequence. I've removed the cmos battery and reinstalled it with no success. I know its possible to flash the bios but have no idea how. Could someone give me a step by step? I've already downloaded the bios file on another computer. Thanks!

How long did you have the battery out of the motherboard (at least 2 minutes or longer is often required).

They provide links to almost all the motherboard makers, so I am sorry that you could not find the manuals that the manufacturer usually has posted in their support area.

Did you disconnect the power supply plug when you removed the cmos battery?

I just saw your second post. If you use that linked site, you can go to the manufacturer's support page and download the bios for your system. The bios upgrades are usually use a zip file, and will require using a program to unzip the file. You will then need a floppy drive to burn the bios file to a floppy, Then you use the floppy to install the bios. IF THE BIOS FLASH FAILS or SOMETHING GOES WRONG, THE COMPUTER IS NOW A DOORSTOP!

Yea Capt. I had to disassemble the whole laptop. Dell stores its passwords on its laptops in a flash chipe separate from the bios chip. I just found a video that shows how to jump it on YouTube. I have to take the motherboard out of the case (completely disassemble it then connect the keyboard and power up the disassembled laptop to jump it. arrrgh!!! I wonder if I can flash the bios from a usb drive and eliminate the hassle?

Hey Capt No links at all for Dell that I could find. Most of the info seems to be targeting towers rather than laptops.

Try removing the CMOS Battery and then hold the on/off switch for several seconds.
