I couldn't fully understand the sentence below.
Does it means, when i flash new bios,it will have a backup for OLD bios?
Correct me if i'm wrong.

“The first instruction that is fetched and executed FOLLOWING a hardware reset is located at physical
address FFFFFFF0h. This address is 16 bytes below the processor’s uppermost physical
address.”1 The Flash ROM containing the Boot Block CODE resides at this address.
There will be one physical ROM which is 16Mbit in capacity. This ROM will contain both the primary and
the backup BIOS ROM images concatenated to create one 16Mbit image
Boot Block
Primary BIOS ROM:FFFF0000hFFFFFFFFh
Primary BIOS/DMI/ESCD:FFF00000hFFFEFFFFh
----------------------------------------
Backup BIOS ROM:
Backup BIOS Boot Block(Unused):FFEF0000hFFEFFFFFh
Backup BIOS/DMI/ESCD:FFE00000hFFEEFFFFh

When the backup BIOS EXECUTES, the primary BIOS
region for ESCD and DMI are updatedIt should, but you can't be sure...Quote from: Ryder17z on May 14, 2008, 11:05:00 AM
