- flash utility. -
Setup Utility — | ;
The ROM-based Setup utility allows the configuration to be modified without opening the system for
most basic changes. The motherboard also incorporates many new capabilities into the Flash
EEPROM, including:
e Auto configuration of IDE hard disk.
e Support for four IDE disk interfaces.
» An option allowing the user to assign a block of addresses below the 1 MB boundary as non-
shadowed, non-cached. This area is primarily used for expansion card ROM which causes timing
problems when shadowed and cached. i
« ISA interrupts assigned to add-in card ISA adapters, thereby informing the PCI configuration
utility which interrupts not to use.
The Setup utility is accessible only during the Power-On Self Test (POST) by pressing the <Del> key
after the POST memory test has begun and before boot begins. A prompt may be enabled that
informs users to press the <Del> key to access Setup utility.
Security features
BIOS Password
A BIOS password feature provides security during the boot process. A password can be entered
using the Setup utility and must be re-entered prior to disk boot each time the system is reset.

Section 3: System Setup
This section provides the information for the system setup procedure and also briefs the setup
procedures for system BIOS.
The system BIOS supports an internal ROM-based system setup utility. When the first time you
power up the system, the system CMOS memory contains incorrect configuration information and the
BIOS prompts you to get into the SETUP utility. The system requires correct configuration
information stored in the CMOS memory. The SETUP utility will guide you to properly configure the
system in a simple and straightforward way. A typical setup procedure is as follows:
1. Properly install the system.
A basic system should include at least
- the SQ588 Pentium motherboard with CPU installed,
- a heat sink and cooling fan for CPU,
- a standard AT case,
- an AT compatible keyboard,
- a floppy drive/controller,
- a monitor/controller,
- two megabyte memory(two 256K x 36 SIMMs), and
- a power supply that provides good airflow.
2. Turn the system power on.
3. The system BIOS will run Power-On-Self-Test(POST). When the test is completed, the system
prompts you to go through the system SETUP utility. You can ignore the prompt if system setup has
been configured correctly.
4. Follow the on-screen instructions provided by the SETUP utility to
- Set Date and Time
- Select correct floppy disk type and number
- Select correct hard disk type and number
- Set the advanced features if necessary
3. Exit the SETUP utility when done
6. System starts to reboot.
7. The system should have correct configuration information by now and should have no problem
booting up the operating system from floppy or hard disk. If not, check the peripheral types, memory
size and connections and go through the SETUP utility again.
PCI device setup allows user to allocate IRQs and specify IRQ's sensitivity for PCI and ISA devices
Follow the on-screen setup instructions and refer to the manual provided with the PCI device for
proper installation.

Appendix G: AMI BIOS Error Messages
During the POST (Power-On-Self-Test) routines, which are performed each time the- system is
powered on, error may occur.
Non-fatal errors are those which, in most cases, allow the system to continue the boot up process.
The error messages normally appear on the screen.
Fatal errors are those which will not allow the system to continue the boot-up procedure. If a fatal
error occurs, you should consult with your system manufacturer for possible repairs. These fatal
errors are usually communicated through a series of audible beeps. The numbers on the fatal error
listed below correspond to the number of beeps for the corresponding error. All errors listed, with
exception of #7, are fatal errors.
Beeps Error Message Description
1 Refresh Failure The memory refresh circuitry on the motherboard is faulty.
2 Parity Error Parity error in the first 64 KB of memory
3 Base 64 KB Memory Failure Memory failure in the first 64 KB.
