Flash Architecture and Flash Update Utility

The flash ROM contains system initialization routines, the BIOS Setup Utility, and runtime
support routines. The exact layout is subject to change, as determined by Intel. A 64-KB user
block is available for user ROM code or custom logos. The flash ROM also contains initialization
code in compressed form for onboard peripherals, like SCSI, NIC and video controllers. It also
contains support for the rolling single-boot BIOS update feature.

BIOS Power On Self Test (POST)

The BIOS Power On Self Test (POST) begins when the system is powered on. During POST,
the BIOS initializes and tests various sub-systems, sets up all major system operating
parameters, and gives the opportunity for any optionally installed add-in cards to execute setup
code. When complete, and if no errors are encountered, BIOS turns control of the system over
to the installed operating system.
As video is initialized during POST, the opportunity to view and alter the POST process is made
available through either a locally attached monitor or through remote console redirection.
4.3.1

User Interface

During the system boot-up POST process, there are two types of consoles used for displaying
the user interface: graphical or text based. Graphics consoles are in 640x480 mode; text
consoles use 80x25 mode.
The console output is partitioned into three windows: the System Activity/State, Splash
Screen/Diagnostic, and POST Activity. The POST Activity window displays information about
the current state of the system. The Splash Screen / Diagnostic window displays the OEM
splash screen or a diagnostic information screen. The POST Activity window displays
information about the currently executing portion of POST as well as user prompts and status
messages.
