Recovery of corrupted BIOS

[GarySober]

I was having Microsoft windows XP operating system installed on my desktop. Last night only I tried to update my motherboard BIOS. I updated my BIOS with a wrong update because of which after starting the system there was no signal on screen but the hard disk was working. I restarted the system again but the same problem was persisting. I need a solution to overcome this problem.

If your motherboard has an Award BIOS, the first recovery option is to remove the PCI graphics card and replace it with an ISA card. The aim is to prevent the BIOS of this card does not load. Then insert the media containing the instruction file and the flashing utility before restarting the machine. Normally you can run the flash again. The second solution is to replace the BIOS battery for another in the goal of access to DOS. It should be noted that this chip should come with a motherboard chipsets are similar or just a motherboard brand. Put your PC on and then once in DOS, remove the backup battery.

You can reset the BIOS very easily. Find the rocker-style switch which is located at the back side of your system and change it from the position 1 to position 0. Remove the CMOS battery and reinsert the CMOS battery again after sometime. Now move the rocker-style to position 1 again. Power on the system and BIOS will be reset.
