As previously stated, this is not really a XP question.
BIOS manufacturers tend to create their chips fast and at the lowest
cost. Some manuafcturers do provide a downgrade path and others make
soem BIOS with a spare chip.
BIOSes are currently extremely important to motherboard as these store
how to access the PC's components correctly so updates most be done
correctly. Update applications must make sure that you the user
definiately want to do an update and must verify that the update
completes correct.
You show also note that Intel is trying to replace the BIOS chips with
a different technology but since BIOS is used on most motherboards, it
will take time.
