How to Repair BIOS Chips
- 1). Cut all power from your PC and remove the case, exposing the motherboard. Note the manufacturer's name, model and other specifications on the label. Replace the case and restart your computer. Visit your manufacturer's website. Download the latest non-beta version of the flasher that is recommended in your manufacturer's manual. Normally, these flashers have .rom or .bin extensions. Common flashers are AwdFlash, AMIFlash, UniFlash and Afudos. Although UniFlash can flash almost any BIOS, check your manual for the supported flasher for your BIOS.
- 2). Reboot your computer and enter setup. Select "Load fail safe defaults," save and reboot. Create a bootable disk that you can be used later if something goes wrong. Also include the following in your disk: your flasher, a new BIOS flash file and "autoexec.bat." Never underestimate the risks of an incorrect flash.
- 3). Reboot your system again and enter setup. Boot the MS-DOS prompt and type the name of your flasher without any parameters. This will show a help screen explaining all the available commands and options. Read them thoroughly before following the instructions. UniFlash has a user interface, which helps beginners to understand and execute the commands. Ensure that nothing interrupts the process of flashing, which shouldn't take more than a minute.
- 4). For an AMI bios, no bootable disk is needed. Rename the flash file to "amiboot.rom" and copy it to an empty disk. Reboot using your new disc and press "Ctrl" plus "home" to launch the flashing process. Your disk drive LED will indicate that the process is running. When the flashing stops, eject the disc and reboot your system.
