Static Electricity Precaution
Static electricity can easily damage your SQ574 mainboard. Observing a few basic
precautions can help you safeguard against damage that could result in expensive repairs.
Follow the simple measures below to protect your equipment from static electricity damage:
Keep the mainboard and other system components in their anti-static packaging until you are
ready to install them.
Touch a grounded surface before you remove any system component from its protective antistatic packaging. Unpacking and installation should be done on a grounded, anti-static mat.
The operator should be wearing an anti-static wristband, grounded at the same points as the
anti-static mat.
After removing the mainboard from its original packing, only place it on a grounded, antistatic surface component side up. Immediately inspect the board for damage. Due to shifting
during shipping, it is suggested that the installer press down on all of the socket IC‘s to
ensure they are properly seated. Do this only with the board placed on a firm flat surface.
During configuration and installation, touch a grounded surface frequently to discharge any
static electrical charge that may have built up in your body. The best precaution is to wear a
grounded wrist strap. When handling the mainboard or an adapter card avoid touching its
components. Handle the mainboard and adapter cards either by the edges or by the adapter
card’s case mounting bracket.

3.2 Installation of the CPU
The SQ574 comes with a 321-pin ZIF socket 7 for installing the CPU. The Socket 7 will also
support future Pentium up-grade processors. It is strongly recommended that a heatsink and
CPU cooling fan be used to prevent the CPU from overheating. (Tip) Applying a thermal
jelly between the CPU and the heatsink/fan will help cool the CPU.
To install a CPU, remember to take the following precautions against static electric
discharge. The basic procedure is as follows:
NOTICE: When installing the CPU into the CPU socket, be sure that PIN 1 of the CPU is
in the same corner as PIN 1 of socket. The CPU is an extremely sensitive electrical
component and can be easily damaged by static electricity.

2) Remove the existing CPU from the ZIF socket by pulling the ZIF lever upwards at a 90
degree angle.
3) Insert the CPU with the correct orientation as shown below. Use the notched (white
dot) corner of the CPU as your guide. The notch in the corner of the CPU should
correspond with PIN 1 of the ZIF socket (Notice: Pin 1 is the blank corner of the ZIF
socket with one hole missing).
4) Once the CPU is inserted close the socket’s lever.
WARNING: Without a fan, the CPU can overheat and will cause damage to both the CPU
and the SQ574 mainboard.
3.3 Installation of Expansion Slots:
3.3.1 ISA & PCI Slots
There are two types of ISA expansion cards, design-Legacy and PnP (Plug & Play). For
Legacy cards you must set the cards’ jumpers manually. For Plug & Play cards, your system
will adjust the IRQs automatically. You can verify the IRQ allocation either by using
Microsoft’s Diagnostic (MSD.EXE) utility which is in the Windows directory or through the
Windows 95 resources menu.

4 BIOS Setup
The SQ574 mainboard uses an Award BIOS, which is stored in a Flash EEPROM and which
can be upgraded using a floppy disk-based program. The BIOS has a built-in Setup program
that allows users to modify the basic system configuration setting. The settings are then
stored in a dedicated battery-backed memory, called CMOS RAM, that retains the
information when the power is turned off. The BIOS provides critical low-level support for
the system central processing, memory, and I/O subsystems. The Award BIOS has been
customized by adding important, but nonstandard, features such as virus and password
protection, power management, and detailed fine-tuning of the chipset controlling the
system. The rest of this manual is intended to guide you through the process of configuring
your system using Setup.
Because jumper settings are no longer needed. The followings show how to clear CMOS
and CPU speed:
1.Clear CMOS:
Keep pushing “F10” until system power is on and booting messages appears on screen.
2.Clear CPU Speed:
Keep pushing “INS” until system power is on and booting messages appears on screen.
4.1 Starting Setup
The Award BIOS is immediately activated when you first turn on the computer. The BIOS
reads system configuration information in CMOS RAM and begins the process of checking
out the system and configuring it through the power-on self test (POST). When these
preliminaries are finished, the BIOS seeks an operating system on one of the data storage
devices (hard drive, floppy drive, etc.). The BIOS launches the operating system and hands
control of system operations to it.
To start Setup, press the <Del> key some time before or while a message similar to this
appears briefly at the bottom of the screen during POST:
TO ENTER SETUP PRESS DEL KEY
If the message disappears before you respond and you still wish to enter Setup, reboot the
system to try again by turning the system OFF then ON or pressing the "RESET" button on
the system case. You may also restart by simultaneously pressing <Ctrl>, <Alt>, and
<Delete> keys. If you do not press the keys at the correct time and the system does not
reboot, an error message will be displayed at the bottom of the screen and you will again be
asked to,
Press F1 to continue, DEL to enter SETUP

4.1.3 In Case of Problems
If, after making and saving system changes with Setup, you discover that your computer no
longer is able to boot, the Award BIOS supports an override to the CMOS settings that
resets your system to its default configuration.
You can invoke this override by immediately pressing Insert; when you restart your
computer. You can restart by either using the ON/OFF switch, the RESET button or by
pressing Ctrl-Alt-Delete.
The best advice is to alter only settings that you thoroughly understand. In particular, do not
change settings in the Chipset screen without a good reason. The Chipset defaults have been
carefully chosen by Award or your system manufacturer for the best performance and
reliability. Even a seemingly small change to the Chipset setup may causing the system to
become unstable.

4.3.3 Hard Disks
The BIOS supports up to four IDE drives. This section does not show information about
other IDE devices, such as a CD-ROM drive, or about other hard drive types, such as SCSI
drives.
NOTE: We recommend that you select type AUTO for all drives.
The BIOS can automatically detect the specifications and optimal operating mode of almost
all IDE hard drives. When you select type AUTO for a hard drive, the BIOS detects its
specifications during POST, every time the system boots.
If you do not want to select drive type AUTO, other methods of selecting the drive type are
available:
4-4
SQ574
1) Match the specifications of your installed IDE hard drive(s) with the preprogrammed
values for drive types 1 through 45.
2) Select USER and enter values into each drive parameter field.
3) Use the IDE HDD AUTO DECTECTION function in Setup.
Here is a brief explanation of drive specifications:
• Type: The BIOS contains a table of pre-defined drive types. Each defined drive type
has a specified number of cylinders, number of heads, write precompensation factor,
landing zone, and number of sectors. Drives whose specifications do not accommodate
any pre-defined type are classified as type USER.
• Size: Disk drive capacity (approximate). Note that this size is usually slightly greater
than the size of a formatted disk given by a disk-checking program.
• Cyls: Number of cylinders
• Head: Number of heads
• Precomp: Write precompensation cylinder
• Landz: Landing zone
• Sector: Number of sectors
• Mode: Auto, Normal, large, or LBA
• Auto: The BIOS automatically determines the optimal mode.
• Normal: Maximum number of cylinders, heads, and sectors supported are 1024,
16, and 63.
• Large: For drives that do not support LBA and have more than 1024 cylinders.
• LBA (Logical Block Addressing): During drive accesses, the IDE controller
transforms the data address described by sector, head, and cylinder number into a
physical block address, significantly improving data transfer rates. For drives with
greater than 1024 cylinders.
4.3.4 Drive A/B type
Select the correct specifications for the diskette drive(s) installed in the computer.
None No diskette drive installed
360K, 5.25 in 5-1/4 inch PC-type standard drive; 360 kilobyte capacity
1.2M, 5.25 in 5-1/4 inch AT-type high-density drive; 1.2 megabyte capacity
720K, 3.5 in 3-1/2 inch double-sided drive; 720 kilobyte capacity
1.44M, 3.5 in 3-1/2 inch double-sided drive; 1.44 megabyte capacity
2.88M, 3.5 in 3-1/2 inch double-sided drive; 2.88 megabyte capacity
SQ574

4.3.5 Video
Select the type of primary video subsystem in your computer. The BIOS usually detects the
correct video type automatically. The BIOS supports a secondary video subsystem, but you
do not select it in Setup.
EGA/VGA
CGA 40 Color Graphics Adapter, power up in 40 column mode.
CGA 80 Color Graphics Adapter, power up in 80 column mode.
MONO Monochrome adapter, includes high resolution monochrome adapters.
Enhanced Graphics Adapter/Video Graphics Array. For EGA, VGA,
SEGA, SVGA or PGA monitor adapters.
4.3.6 Halt on
During the power-on self-test (POST), the computer stops if the BIOS detects a hardware
error. You can tell the BIOS to ignore certain errors during POST and continue the boot-up
process. These are the selections:
No errors POST does not stop for any errors.
All errors If the BIOS detects any non-fatal error, POST stops and prompts
you to take corrective action.

other errors.
POST does not stop for a keyboard or disk error, but stops for
all other errors.
4.3.7 Memory
You cannot change any values in the Memory fields; they are only for your information. The
fields show the total installed random access memory (RAM) and amounts allocated to base
memory, extended memory, and other (high) memory. RAM is counted in kilobytes (KB:
approximately one thousand bytes) and megabytes (MB: approximately one million bytes).
RAM is the computer's working memory, where the computer stores programs and data
currently being used, so they are accessible to the CPU. Modern personal computers may
contain up to 64 MB, 128 MB, or more.
Base Memory
Typically 640 KB. Also called conventional memory. The DOS operating system and
conventional applications use this area.
Extended Memory
Above the 1-MB boundary. Early IBM personal computers could not use memory above 1
MB, but current PCs and their software can use extended memory.
4-6
SQ574
Other Memory
Between 640 KB and 1 MB; often called High memory. DOS may load terminate-and-stayresident (TSR) programs, such as device drivers, in this area, to free as much conventional
memory as possible for applications. Lines in your CONFIG.SYS file that start with
LOADHIGH load programs into high memory.
Total Memory
System total memory is the sum of base memory, extended memory, and other memory.

4.4.1 Virus Warning
When enabled, you receive a warning message if a program (specifically, a virus) attempts to
write to the boot sector or the partition table of the hard disk drive. You should then run an
anti-virus program. Keep in mind that this feature protects only the boot sector, not the
entire hard drive.
NOTE: Many disk diagnostic programs that access the boot sector table can trigger the
virus warning message. If you plan to run such a program, we recommend that you first
disable the virus warning.

4.4.2 External Cache
Cache memory is additional memory that is much faster than conventional DRAM (system
memory). When the CPU requests data, the system transfers the requested data from the
main DRAM into cache memory, for even faster access by the CPU. The External Cache
field may not appear if your system does not have external cache memory.
4.4.3 Quick Power On Self Test
Select Enabled to reduce the amount of time required to run the power-on self-test (POST).
A quick POST skips certain steps. We recommend that you normally disable quick POST.
Better to find a problem during POST than lose data during your work.
4-8
SQ574
4.4.4 Boot Sequence
The original IBM PCs loaded the DOS operating system from drive A (floppy disk), so IBM
PC-compatible systems are designed to search for an operating system first on drive A, and
then on drive C (hard disk). However, the BIOS now offers 10 different boot sequence
options of three drives each. In addition to the traditional drives A and C, options include
IDE hard drives D, E, and F; plus a SCSI hard drive and a CD-ROM drive.
4.4.5 Swap Floppy Drive
This field is effective only in systems with two floppy drives. Selecting Enabled assigns
physical drive B to logical drive A, and physical drive A to logical drive B.
4.4.6 Boot Up Floppy Seek
When Enabled, the BIOS tests (seeks) floppy drives to determine whether they have 40 or
80 tracks. Only 360-KB floppy drives have 40 tracks; drives with 720 KB, 1.2 MB, and 1.44
MB capacity all have 80 tracks. Because very few modern PCs have 40-track floppy drives,
we recommend that you set this field to Disabled to save time.
4.4.7 Boot Up NumLock Status
Toggle between On or Off to control the state of the NumLock key when the system boots.
When toggled On, the numeric keypad generates numbers instead of controlling cursor
operations.
4.4.8 Typematic Rate Setting
When Disabled, the following two items (Typematic Rate and Typematic Delay) are
irrelevant. Keystrokes repeat at a rate determined by the keyboard controller in your system.
When Enabled, you can select a typematic rate and typematic delay.
4.4.9 Typematic Rate (Chars/Sec)
When the typematic rate setting is enabled, you can select a typematic rate (the rate at which
character repeats when you hold down a key) of 6, 8, 10,12, 15, 20, 24 or 30 characters per
second.
4.4.10 Typematic Delay (Msec)
When the typematic rate setting is enabled, you can select a typematic delay (the delay
before key strokes begin to repeat) of 250, 500, 750 or 1000 milliseconds.
4.4.11 Security Option
If you have set a password, select whether the password is required every time the System
boots, or only when you enter Setup.
SQ574

4.4.12 Assign IRQ for VGA
Assign the IRQ# for VGA card.
4.4.13 OS select for DRAM > 64MB
Select OS2 only if you are running OS/2 operating system with greater than 64 MB of RAM
on your system.
4.4.14 Shadow
Software that resides in a read-only memory (ROM) chip on a device is called firmware. The
Award BIOS permits shadowing of firmware such as the system BIOS, video BIOS, and
similar operating instructions that come with some expansion peripherals, such as, for
example, a SCSI adaptor.
Shadowing copies firmware from ROM into system RAM, where the CPU can read it
through the 16-bit or 32-bit DRAM bus. Firmware not shadowed must be read by the system
through the 8-bit X-bus. Shadowing improves the performance of the system BIOS and
similar ROM firmware for expansion peripherals, but it also reduces the amount of high
memory (640 KB to 1 MB) available for loading device drivers, etc.
Enable shadowing into each section of memory separately. Many system designers hardwire
shadowing of the system BIOS and eliminate a System BIOS Shadow option.
Video BIOS shadows into memory area C0000-C7FFF. The remaining areas shown on the
BIOS Features Setup screen may be occupied by other expansion card firmware. If an
expansion peripheral in your system contains ROM-based firmware, you need to know the
address range the ROM occupies to shadow it into the correct area of RAM.

4.5.5 8/16 Bit I/O Recovery Time
The I/O recovery mechanism adds bus clock cycles between PCI-originated I/O cycles to the
ISA bus. This delay takes place because the PCI bus is so much faster than the ISA bus.

4.7.6 PCI IDE IRQ Map To
This field lets you select PCI IDE IRQ mapping or PC AT (ISA) interrupts. If your system
does not have one or two PCI IDE connectors on the system board, select values according to
the type of IDE interface(s) installed in your system (PCI or ISA). Standard ISA interrupts
for IDE channels are IRQ14 for primary and IRQ15 for secondary.
4.7.7 Primary/Secondary IDE INT#
Each PCI peripheral connection is capable of activating up to four interrupts: INT# A, INT#
B, INT# C and INT# D. By default, a PCI connection is assigned INT# A. Assigning INT# B
has no meaning unless the peripheral device requires two interrupt services rather than just
one. Because the PCI IDE interface in the chipset has two channels, it requires two interrupt
services. The primary and secondary IDE INT# fields default to values appropriate for two
PCI IDE channels, with the primary PCI IDE channel having a lower interrupt than the
secondary.
