3.2 BIOS Update Utility

The flash ROM contains system initialization routines, the BIOS
Setup Utility, and runtime support routines. The exact layout is
subject to change, as determined by BIOS. The flash ROM also
contains initialization code in compressed form for onboard
peripherals, like SCSI, NIC and video controllers. The complete
ROM is visible, starting at physical address 4 GB minus the size
of the flash ROM device.
A 16-KB parameter block in the flash ROM is dedicated to stor-
ing configuration data that controls the system configuration
(ESCD). Application software must use standard APIs to
access these areas; application software cannot access the
data directly.
