System Bios; Bios Identification String - Intel SE7525GP2 Technical Manual

System BIOS

4. System BIOS
This section describes 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
features. The Flash ROM also contains firmware for embedded PCI devices.
The 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.

Dxx = Development
Xxx = Power On
Axx = Alpha BIOS
Bxx = Beta BIOS
RCxx= Release Candidate
P = Production
xx = 2 digit number N/A for Production
Three characters:
N character ID: 86A = Intel DPG
AN430TX, etc. 86B = Intel EPG
10A = Some OEM, etc.
