BIOS

Overview
The Basic Input Output System (BIOS) provides an interface between the operating system and
the hardware of the blade. It is used for hardware configuration. Before loading the operating
system, BIOS performs basic hardware tests and prepares the blade for the initial boot-up
procedure.
During blade production, identical BIOS images are programmed into both boot flash banks.
It is possible to select boot flash as device to boot from. This is done via an IPMI command. For
further details refer to section

The BIOS used on the blade is based on the AMI UEFI BIOS with several Artesyn extensions
integrated. Its main features are:
Initialize CPU, chipset and memory
