HP BIOS Overview Overview This chapter summarizes the HP x2000 Workstation's Setup program and BIOS. Chapter 4, "Tests and Error Messages," describes the POST routines. The BIOS is based on the core Phoenix BIOS, which includes 4Mbits of flash memory, support for PCI Specification 2.2, 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 Power-On Self-Test (POST) routines and the BIOS: the system BIOS, video BIOS, and low-option ROM. This chapter (and Chapter 4) gives an overview of the following: • Menu-driven Setup with context-sensitive help. • The address space, with details of the interrupts used. • POST routines, which are a sequence of tests the computer performs to ensure that the system is functioning correctly. See Chapter 4 for information. The system BIOS is identified by the version number IY.WM, where: • IY is a two-letter code indicating that it is for the x2000. • 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: IY.W1.05. See page 86 for the procedure for updating the system ROM firmware. 78 Chapter 3
