For the onboard VGA device, the VGA BIOS is combined with
the SYSTEM BIOS. If you want to update the VGA BIOS, you
must update the SYSTEM BIOS as well (you cannot update
the VGA BIOS only). However, Intel chipsets support the
"Video BIOS Update" specification, which provides two VGA
BIOS in the SYSTEM BIOS. One is the original, and the other
is a space for future (VBU Block) VGA BIOS; you can select
one of them to be active.
