BIOS
6.1 Introduction
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
System Boot Options Parameter #96 on page 234 .
The BIOS used on the blade is based on the Insyde UEFI BIOS with several Artesyn Embedded
Technologies 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
The BIOS complies with the following specifications:
 UEFI Specification 23.1
 Plug and Play BIOS Specification 1.0A
 PCI BIOS Specification 2.1
 SMBIOS Specification 2.8
 BIOS Boot Specification 1.01
 PXE 2.1
 Multiprocessor Specification 1.4
 ACPI 5.0
The BIOS setup program is required to configure the blade hardware. This configuration is
necessary for operating the blade and connected peripherals. The configuration data are
stored in the same flash device from which the board boots.
