This file contains 3 versions of flash bios for the Gigabyte GA-6VXC7-4X motherboard.
early version: FA (released in 1999)
more recent version: FB (released in 2000)
latest version: fc (released in 2002)
Unzip to a temp folder, you will now have 3 zip files with all bios releases for this mb. Just pick the one you wish to install.
Each file has it own flash exe program. Be sure to use only the exe file included with each flash file.
Note: I did not select os in selection list as bios is not os dependant.
