Intel® Server Board SE7320SP2 & Intel Server Board SE7525GP2 TPS System BIOS
Revision 2.0
69
4. System BIOS
This section details the functionality and features supported of the System Basic Input/Output
System (BIOS) which is based on an AMI 8.0 core architecture. The BIOS is implemented as
firmware that resides in Flash ROM. It provides hardware-specific initialization algorithms and
standard PC-compatible basic input/output (I/O) services, and standard Intel
®
Server Board
features. The Flash ROM also contains firmware for embedded PCI devices.
The SE7320SP2 / SE7525GP2 BIOS is comprised of the following components:
• IA-32 core BIOS. This component contains most of the standard services and
components found in an IA-32 system, such as the PCI Resource manager, ACPI
support, POST, and RUNTIME functionality.
• The “EFI” is the extensible firmware interface. This is an abstraction layer between the
operating system and system hardware.
• Server BIOS extensions: Support for Baseboard Management Controller (BMC) and
Intelligent Platform Management Interface (IPMI).
• Processor Microcode Updates: The BIOS also includes latest processor microcode
updates.
4.1 BIOS Identification String
The BIOS Identification string is used to uniquely identify the revision of the BIOS being used on
the system. The string is formatted as follows:
BoardId.OEMID.BuildType.Ma
j
or.Minor.BuildID.BuildDateTime.Mod
two digits:
Dxx = Development
Xxx = Power On
Axx = Alpha BIOS
Bxx = Beta BIOS
RCxx= Release Candidate
P = Production
xx = 2 di
g
it number N/A for Production
Four digits:
Increment
on each build
Three characters:
10A = Some OEM, etc.
N character ID:
AN430TX, etc.
86A = Intel DPG
86B = Intel EPG
One digit:
non-zero if any Separately
Updateable
Module has been updated
two digits:
Build Date and time in
MMDDYYYYHHMM format
During board development, the system BIOS will have a unique BIOS ID for Intel Sever Board
SE7320SP2 and SE7525GP2. The following is a sample data string that will be displayed
during POST:
SE7320SP2.86B.P.05.00.0028.10072004
SE7525GP2.86B.P.05.00.0028.10072004
