Select your motherboard (or system): Use only BIOS versions that apply to your motherboard (or system) make and model (see Screenshot N.)

Visit your motherboard (or system) manufacturer's Web site, and check out their support pages. Look for the make and model of your motherboard or system; see Screenshot N. Most of these entries use designations such as "GA-686BX", "A7N8X-E" or "K8T Neo2". If your search turns up no matches, use only the model name instead. Sometimes this won't help either, though, perhaps because the motherboard name on the packaging (for example "K8T-Neo") differs from its technical description (for example "MS-6702 Version 1.0"). Should this happen, switch to the product listings on the Web site instead, and follow the right path to select the motherboard (or system) model that you own. Once you find your match, you can then select "Downloads" or "Support" to find what you need.

39. Archiving BIOS Versions

Some people download BIOS update files from the manufacturer's website regularly, even when they may not need them: for example, to assess experimental, alpha, or beta releases, or changes not relevant to specific installations. You can always replace later updates that you may not like or that cause problems with older BIOS versions. Always read the Readme file that accompanies any BIOS update through completely before you install it. The file will describe exactly what changes and enhancements are included in the associated BIOS version.
