System BIOS

8.1Introduction

The Basic Input/Output System (BIOS) of the computer is a collection of machine language programs stored as firmware in read-only memory (ROM). The system BIOS includes such functions as Power-On Self Test (POST), PCI device initialization, Plug 'n Play support, power management activities, and the Setup utility. The firmware contained in the system BIOS ROM supports the following operating systems and specifications:

■Windows XP (Home and Professional versions)

■Windows Vista Business 32-/64-Bit

■Windows Vista Enterprise 32-/64-bit

■Windows Vista Home Basic 32-/64-Bit

■Windows Vista Home Premium 32-/64-Bit

■Windows Vista Ultimate 32-/64-Bit

■Windows 7 32-Bit Enterprise/Home Basic/Home Premium/Professional/Ultimate

■Windows 7 64-Bit Enterprise/Home Basic/Home Premium/Professional/Ultimate

■SCO Unix

■DMI 2.1

■Intel Wired for Management (WfM) ver. 2.2

■Alert Standard Format (ASF) 2.0

■ACPI and OnNow

■SMBIOS 2.5

■Intel PXE boot ROM for the integrated LAN controller

■BIOS Boot Specification 1.01

■Enhanced Disk Drive Specification 3.0

■“El Torito” Bootable CD-ROM Format Specification 1.0

■ATAPI Removeable Media Device BIOS Specification 1.0

■Serial ATA Advanced Host Controller Interface (AHCI) 1.2

■ATA with Packet Interface (ATA/ATAPI-7)

The BIOS firmware is contained in a 32 Mb flash ROM part. The runtime portion of the BIOS resides in a 128KB block from E0000h to FFFFFh.
