Board BIOS
The Processor Board uses a Phoenix BIOS, which is stored in Flash ROM. The

and APM 1.2. The board also supports system BIOS shadowing, allowing the
BIOS to execute from onboard write-protected DRAM.

Advanced Power Management

The Processor BIOS has support for both 1.1 and 1.2 Advanced Power
Management (APM). The version of APM drivers loaded in the operating
system by the user will determine what specification the BIOS will adhere too.
In either case the energy saving Stand-by mode can be initiated by a keyboard
hot key sequence or a time-out period set by the user.
