Note: Before downloading any bios updates,
make sure you know which board version you have. Determine this by looking next
to the keyboard connector. v3.2/3.2A bios updates are not compatible with v7.0A
boards and visa versa.Flashing your bios with the wrong file will render your
board useless. The release dates shown here are in the style of the USA: month/date/year, since this is the format that was
used in the BIOS release notes.

bios on the M571.
AMI Bios Flashing Utility
WARNING
-
this utility must NEVER be run from within Windows. To do so may completely
trash your BIOS. There have been reports that even clicking on the filename
when in Windows is enough to do this. I would urge you to only keep this
utility on floppy disk when in unzipped form. This utility works best when used on a
boot disk, which must be made from Windows 98 or 95, or an older version of
DOS. A boot disk made from Windows ME, Windows XP, or Windows 2000 will not
work with the amifl632.exe flash utility. See these instructions for information on how to
flash your BIOS.
