PXH PCI bridge to support PCI-X /PCI-X DDR
• 4-MB flash ROM to provide BIOS code storage.
• National Semiconductor* PC87427 Super I/O to integrate Serial Ports/PS/2
KB/MS/Floppy and hardware monitor functionality.
• ATI* RAGE XL with 8-MB SDRAM support
• LSI* 53C1030 SCSI controller providing dual channel Ultra-320
• Intel® 82541PI NIC providing single channel 10/100/1000
• Marvell* “Yukon” 88E8050 NIC providing single channel 10/100/1000
3.1.4 BIOS POST
The BIOS supports one system splash screen. When the system is booting, the BIOS displays
the splash screen instead of BIOS messages. The user can view BIOS messages by pressing
the ‘ESC’ key during POST. Once the BIOS POST message screen is selected, the splash
screen is no longer accessible during the current boot sequence. The splash screen can be
customized by using the ‘Change Logo’ utility. Refer to the Change Logo for AMIBIOS User’s
Guide (Version 2.22) for details.
3.1.5 User Interface
Two types of consoles are used for displaying the user interface: graphical or text-based.
Graphical consoles are displayed in 640x480 mode. Text-based consoles are displayed in
80x25 mode.
Console output is partitioned into three areas: System State Window, Logo/Diagnostic Window,
and Current Activity Window. The System State Window displays information about the current
state of the system (i.e., is it active, hung, or requires user intervention). The Logo/Diagnostic
Window displays the OEM splash screen logo or a diagnostic boot screen. The Current Activity
Window displays information about the currently executing portion of POST as well as user
prompts or status messages.
