not far off though surely ,the first PC that I built had a gigabyte board ,if I remember correctly it was a GA7-DXR+ and at the time a state of the art althon 1800xp processor .
that board had dual bios and that was around 8 years ago ,early 2003. I believe Gigabyte was using dual bios a year or two before that .
as far as Express bios is concerned I have never heard of it ,and all my PCs "around 80ish " so far have had exclusively Gigabyte boards ,and only once in that time did I ever have a corrupted bios and was able to recover .
I think Gig Thug is mistaken and that he is actually thinking of Express recovery ,that is a utility to create a backup of your OS at the end of the drive .and can be used in the event of a damaged OS to restore the OS back to the time of the Backup . this utility has nothing to do with the bios ,to the best of my knowledge .
