Introduction
BIOS (Basic Input Output System) 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 the blade

and user flash. By default the blade boots from the boot flash. It is possible to select
between boot and user flash as device to boot from. This is done via a OEM IPMI
command. For further details refer to the

The BIOS set−up program is required to configure the hardware of the blade. This
configuration is necessary for operating the blade and connected peripherals. It is stored
in the battery backed−up CMOS memory as well as in the blade’s boot flash.
