Board BIOS
The Processor Board uses a Phoenix BIOS, which is stored in Flash
ROM and easily upgraded through the network connection or serial
port. The Flash EEPROM also contains the Setup utility, Power-On Self
Tests (POST), and APM 1.2. The board also supports system BIOS
shadowing, allowing the BIOS to execute from onboard write-
protected DRAM.
The BIOS displays a sign-on message during POST identifying the type
of BIOS and a five-digit revision code.
FLASH memory Implementation
The Intel E28F800B5-T70 Flash component is organized onboard as
1024 K x 8 (1 MB). While a typical PC BIOS image including video and
LAN boot ROM code normally fits in 256 K on the Pentium Board and
512 K in the Pentium III/Celeron board, the boards support a 1 MB
flash ROM. The current Phoenix BIOS release only requires 256 K of
this 1 MB total. The Flash device contains the PC System BIOS along
with the Video BIOS and LAN boot ROM which compresses the ROM
images into a single binary image.
