This can be done either from within Windows (if a dual-boot situation), on a Floppy Drive using either the vendor-provided BIOS software or the BIOS's builtin BIOS updating software, or with a small FAT partition containing the vendor-provided update software and a CD-ROM containing the FreeDOS operating system.

Fix for Full-Screen Resize (e.g. during a game) Driving Monitor at Wrong Frequency with Intel Video on Gigabyte GA-8I865GME-775 (and possibly other) Motherboards
Description
When changing screen resolutions on a Gigabyte GA-8I865GME-775 motherboard (and potentially others as well) with the F2 BIOS version (and possibly lower), the builtin Intel video chip drives the signal (VGA) at an incorrect frequency. This may be noticed by the user as a message from the monitor, such as "Signal Over Range!" on the Tyris T701DB, or simply a lack of video output. There may also be messages in /var/log/Xorg.log.0 about failed VBIOS checksums.
Solution
While not at all obvious when seeing the misbehavior, the solution is to download and install the F3 BIOS version for the Gigabypte GA-8I865GME-775 motherboard. This can be done either from within Windows (if a dual-boot situation), on a Floppy Drive using either the vendor-provided BIOS software or the BIOS's builtin BIOS updating software, or with a small FAT partition containing the vendor-provided update software and a CD-ROM containing the FreeDOS operating system.
