The SPI Flash contains the BIOS Setup program, 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 initial production BIOSs are identified as CL94510J.86A. When the BIOS Setup configuration jumper is set to configure mode and the computer is powered-up, the BIOS compares the CPU version and the microcode version in the BIOS and reports if the two match. The BIOS Setup program can be used to view and change the BIOS settings for the computer. The BIOS Setup program is accessed by pressing the key after the Power-On Self-Test (POST) memory test begins and before the operating system boot begins. The menu bar is shown below. Maintenance Main Advanced Security Power Boot Exit NOTE The maintenance menu is displayed only when the Desktop Board is in configure mode. Section 2.8 on page 56 shows how to put the Desktop Board in configure mode. 65
