HP BIOS

This chapter summarizes the Setup program and BIOS of the HP Kayak XU700 PC Workstation. The POST routines are described in the next chapter.

The BIOS is based on the core Phoenix BIOS, which includes 4 M/bits of flash memory, support for PCI 2.2 Specification, suspend to RAM, and RIMM or DIMM memory modules.

The BIOS includes a Boot ROM for the 3COM 3C905C and HP LAN cards.

The System ROM contains the POST (Power-On Self-Test) routines, and the BIOS: the System BIOS, video BIOS, and low option ROM. This chapter, together with the subsequent chapter, gives an overview of the following aspects:

•Menu-driven Setup with context-sensitive help, described next in this chapter.

•The address space, with details of the interrupts used, described at the end of this chapter.

•The Power-On Self-Test or POST, which is the sequence of tests the computer performs to ensure that the system is functioning correctly, described in the next chapter.

The system BIOS is identified by the version number IX.WM, where:

•IX is a two-letter code indicating that it is for the Kayak XU700.

•W is a one-digit code indicating the HP entity.

•M is the major BIOS version.

An example of a released version would look similar to the following the example: IX.W1.05.

The procedure for updating the System ROM firmware is described on page 87.
