Introduction
The BIOS is stored in the Firmware Hub (FWH) and can be updated using a BIOS flash
programming tool. The FWH contains the BIOS Setup program, Power On Self Test
(POST), the PCI auto-configuration utility, and plug-and-play support.
The BIOS displays a message during POST identifying the type of BIOS and a revision
code.
The BIOS Setup program can be used to view and change the BIOS settings for the
CRB. The BIOS Setup program is accessed by pressing the <DELETE> key after the
POST test and memory test begins and before the operating system begins to boot.
The menu bar is shown below.
