Bios Flash - Intel 5000 Series Datasheet

Functional Architecture
2.4.18.1 General Purpose Input/Output (GPIO)
The National Semiconductor* PC87427 Super I/O provides nine general-purpose input/output
pins that the server and workstation boards utilize.
Note: See the server or workstation Technical Product Specification that applies to your product
for information.
2.4.18.2 Removable Media Drives
The BIOS supports removable media devices in accordance with the Tested Hardware and
Operating System List. The BIOS supports booting from USB mass storage devices connected
to the chassis USB port, such as a USB flash drive device. The BIOS supports USB 2.0 media
storage devices that are backward compatible to the USB 1.1 specification.
2.4.18.3 Keyboard and Mouse
Dual stacked PS/2* ports on the back edge of the server board support a keyboard and mouse.
Either port can support a mouse or keyboard. Neither port supports hot plugging, or connector
insertion, while the system is turned on.
The system can boot without a keyboard or mouse attached. If present, the BIOS will detect the
keyboard during POST and displays the message "Keyboard Detected" on the POST screen.
2.4.18.4 Wake-up Control

BIOS Flash

The BIOS supports the Intel
which 2 MB is programmable. The flash ROM contains system initialization routines, a setup
utility, and runtime support routines. The layout is subject to change, as determined by Intel.
The flash ROM contains the necessary drivers for onboard peripherals such as SCSI, Ethernet,
and video controllers. The Flash Memory Update utility loads the BIOS image into the flash.
