BIOS
4.1 Features
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 test, known as power-on self tests (POST) 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
Chapter 8, Supported IPMI Commands, on page 183 .
The BIOS used on the blade is based on the Phoenix SecureCore Tiano (SCT) UEFI BIOS with
several Artesyn extensions integrated. Its main features are:
 Initialize CPU, chipset and memory
 Initialize PCI devices
 Setup utility for setting configuration data
 IPMC support
 Serial console redirection for remote blade access
 Boot operation system
