Note the screen display and write down the beep code you hear; this information is useful for your
service representative. For a listing of beep codes and error messages that POST can generate, see
Chapter 7, “Solving Problems,” beginning on page 155.
Using BIOS Setup
This section describes BIOS Setup options. Use Setup to change the system configuration
defaults. You can run Setup with or without an OS being present. Setup stores most of the
configuration values in battery-backed CMOS; the rest of the values are stored in flash memory.
The values take effect when you boot the system. POST uses these values to configure the
hardware; if the values and the actual hardware do not agree, POST generates an error message.
You must then run Setup to specify the correct configuration.
Run Setup: you can run Setup to modify any standard PC AT† feature such as:
• Select diskette drive
• Select parallel port
• Select serial port
• Set time/date (to be stored in RTC)
• Configure IDE hard drive
• Specify boot device sequence
• Enable SCSI BIOS
Run SSU, not Setup: You must run the SSU instead of Setup to do the following:
• Enter or change information about a board
• Alter system resources (e.g., interrupts, memory addresses, I/O assignments) to user-selected
choices instead of choices selected by the BIOS resource manager

Record Your Setup Settings

Worksheets for recording your settings are in Appendix B, “Equipment Log and Configuration
Worksheets”, starting on page 197. If the default values ever need to be restored (after a CMOS
clear, for example), you must run Setup again. Referring to the worksheets could make your task
easier.

If You Cannot Access Setup

If the diskette drive is misconfigured so that you cannot access it to run a utility from a diskette,
you might need to clear CMOS memory. You must open the system, change a jumper setting, use
Setup to check and set diskette drive options, and change the jumper back. For a step-by-step
procedure, see "CMOS Clear Switch" on page 183.
