Flash Architecture and Flash 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 Intel. A 64KB user
block is available for user ROM code or custom logos. The flash ROM also contains initialization
code in compressed form for onboard peripherals, such as NIC and video controllers. It also
contains support for the rolling single-boot BIOS update feature.
The complete ROM is visible, starting at physical address 4 GB minus the size of the flash ROM
device.
A 16KB parameter block in the flash ROM is dedicated to storing 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.
