Identifying and Flashing the BIOS

Flashing the BIOS: replacing the software subroutines in the current BIOS with an updated image that holds new instructions. Usually used to fix system bugs not having to do with the OS, or to expand system capabilities. DO NOT FLASH THE BIOS UNLESS EXPLICITLY INSTRUCTED TO DO SO AND YOU KNOW WHAT YOU ARE DOING

Flash BIOS Procedures

- If the BIOS belongs to a major vendor system, simply find the BIOS on that vendor's download site.
- If the BIOS belongs to a mom n' pop system, and you can identify the motherboard, you can get the update from that motherboard's site.

BIOS flash procedures vary from vendor to vendor. Generally, the process involves:

- Downloading the 'image' that will replace the current BIOS.
- Extracting the image to a floppy disk.
- Booting the system with that floppy. The update is usually automatic, or provides instructions.

Note: Some vendors, like ASUS motherboards, require you to download an update program, AND a separate image to the same floppy.
