Basic Input/Output System (BIOS)

13. Basic Input/Output System (BIOS)
This chapter describes the functionality of the Basic Input Output System (BIOS) for the Intel
Server System S7000FC4UR. It is written for persons involved in design, validation, integration,
manufacture, and support. It is assumed that the reader is familiar with Intel
the standards that define server architecture.

13.1 BIOS Architecture

The BIOS is implemented as firmware that resides in the Flash ROM. It provides hardware-
specific initialization algorithms, standard PC-compatible basic input / output (I/O) services, and
®
standard Intel server board features. The Flash ROM contains firmware for certain embedded
devices. These images are supplied by the device manufacturers and are not specified in this
document.
The BIOS implementation is based on the Intel
architecture and is compliant with all Intel Platform Innovation Framework for the EFI
architecture specifications specified in the Extensible Firmware Interface Reference
Specification, Version 1.1. The Intel Platform Innovation Framework for EFI is referred to as
"Framework" in this document.
13.1.1

Data Structure Descriptions

Data structures in this document are described in "little endian" format. This means that the low-
order byte of a multi-byte data item in memory is at the lowest address, while the high-order
byte is at the highest address. In some memory layout descriptions, certain fields are marked
reserved. Software must initialize such fields to zero, and ignore them when read. On an update
operation, software must preserve any reserved field.

13.2 BIOS Identification String

The BIOS Identification string is used to uniquely identify the revision of the BIOS being used on
the server. The string is formatted as follows:
BoardFamilyID.OEMID.MajorRev.MinorRev.BuildID.BuildDateTime
Where:
BoardFamilyID = String name for this board family.
OEMID = Three-character OEM ID. "86B" is used for Intel EPSD.
MajorRev = Two decimal digits
MinorRev = Two decimal digits
BuildID = Four decimal digits
BuildDateTime = Build date and time in MMDDYYYYHHMM format:
MM = Two-digit month
-
DD = Two-digit day of month
-
96
