3. INSTALLATION
Precaution Before Start
Static Electricity Damage:
Static electricity can easily damage your motherboard.
Observing a few basic precautions will help safeguard
against damage that could result in expensive repairs.
Please read the following before you begin installation.
1. Keep the motherboard and other system components in their anti-static
packaging until you are ready to install them.
2. Touch a grounded surface before you remove any system component from its
protective anti-static 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.
3. After removing the motherboard from its original packaging, place only on a
grounded, anti-static surface, component side up. Immediately inspect the
board for damage. Due to shifting during shipping it is suggested that the
installer press down on the entire socket ICs to ensure they are properly
seated. Do this only with the board placed on a firm flat surface.
4. 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, as stated above, is to wear a grounded wrist strap. When
handling the motherboard or an adapter card avoid touching its components.
Handle the motherboard and adapter cards either by the edges or by the
adapter card case-mounting bracket.
Misplaced Jumper Damage:
There are critical headers used for connectors or power
sources. These are clearly marked separately from the
jumpers listed in “Motherboard Layout”. Incorrectly setting
jumpers and connectors may lead to damage to your
motherboard. Please pay special attention to avoid
connecting these headers in the wrong directions.
3. INSTALLATION
3.1 Slots and Connectors

DIMM (Asymmetrical single and double sided). The DRAM interfaces on a 64-bit
wide, data path. Also supported is 3.3 volts 66.67Mhz unbuffered Synchronous DRAM
(SDRAM) and 3.3 volts 60ns or faster unbuffered EDO DRAM. The EDO DRAM and
SDRAM are defined above.
3. INSTALLATION
3.4 Expansion Slots ( J17 )
The SL5598 system will support an ISA only, PCI only or shared ISA-PCI slots riser
card. The ISA/PCI I/O riser card contains decoupling capacitors between the voltage
planes and ground to assist in both EMI and general voltage plane noise reduction.
The ISA/PCI I/O riser will be inserted into the system PWA during the system
assembly process. The riser connects to the system PWA through the J17 connector.
ISA Interface
The SL5598 incorporates a fully ISA bus compatible master and slave interface. It is
capable of driving Max. five (5) ISA slots without external data buffers. This drive
capability is required to ensure signal integrity for the ISA bus under loading
conditions with the ISA/PCI I/O riser and expansion cards installed. The ISA interface
also provides byte swap logic and I/O recovery support.
ISA Bus Speed
Dividing the PCI clock by 3 or 4 generates the ISA system clock. The division by 3
setting is used for 25MHz PCI bus speed, division by 4 is used for 30 and 33MHz. The
frequencies supported are 8.25MHz, 7.5MHz and 8.33MHz respectively. The ISA bus
frequency is selected during the system’s power up or hard reset through a hardware
strapping option (Divide x3 or x4) and the selected PCI bus clock speed.
AT Bus Refresh
The SL5598 system board supports hidden refresh cycles which allows the CPU to
continue to execute unless an AT bus cycle is attempted coincident with the AT bus
refresh cycle (ISA Bus refresh cycles are completely decoupled from DRAM Refresh).
Transactions driven by PCI masters that target ISA or IDE resources while refresh is
active are held off with wait states until the refresh is complete.
ISA / PCI /I/O Riser
3. INSTALLATION
PCI Interface
The main function of PCI arbiter is to take charge of the PCI bus ownership
assignment. This PCI arbiter supports at most 4 external PCI masters and 4 internal
PCI masters This arbitration operation is applied to the Host Bridge and CPU.
The arbitration scheme, which we design, is done at two layers. CPU has the highest
priority (i.e. CPU will be the PCI bus owner if there is a request from the Host Bridge.
If there is no request from the Host Bridge, rotational priority scheme will be applied
to these masters).
The SiS5598 Pentium PCI/ISA chipset provides high performance PCI Arbiter. The
SL5598 supports up to 2 PCI Masters, fully compliant to PCI2.1.
3. INSTALLATION

Are all the DRAM modules installed properly? (Sec. 3.3)
Are all expansion card (Riser Card,VGA, Sound…. etc.)
inserted? (Sec. 3.4)
Are all the connectors described in Sec 3.5 properly
connected to their variable devices? (Sec. 3.5)
l Yes, I have checked and completed the above steps!
Now get ready to turn on your device by following these steps.
Mount your motherboard to the chassis frame and close the
chassis cover.
Switch off all power.
Connect the power supply cord to inlet of the system case.
Connect the power supply cord into an outlet of power
supply.
Connect monitor signal cable to system VGA port, and the
monitor power cord to power outlet.
6. Turn on monitor and system power.
Once Powered on, the power LED on the front panel of the system case will light. For
ATX power supplies, the system LED will light when the ATX power switch is
pressed.
The system will then perform a power-on test on each item one at a time. Additional
messages will appear on screen at this time. If the screen blinks or the tests stops
more than 30 seconds, the system may have failed
the power-on test. If this happens, please recheck
the above steps or call your retailer for assistance.
If all the “power-on” tests pass you are ready to
enter BIOS setup. Do this now by holding down the
<Delete> button on the keyboard. Follow the
instructions in the next chapter, BIOS SETUP.
3. INSTALLATION

The SL5598 motherboard uses AWARD
BIOS, which is stored in a Flash EEPROM
and can be upgraded by a floppy disk-based
program. The BIOS has a built-in Setup
Program which allows users to modify the
basic system configuration settings. 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’s
central processing, memory and I/O subsystems. The AWARD BIOS has been
customized by adding important, nonstandard, features such as virus and password
protection, power management, and detailed fine-tuning of the chipset which controls
the system. The remainder of this manual is intended to guide you through the process
of configuring your system using the BIOS Setup.
4.1 How To Enter BIOS 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 the system and configuring it through the power-on self test (POST). When
these preliminaries are completed, the BIOS searches for an operation system on the
data storage devices (hard drive, floppy drive, etc.). The BIOS launches the operating
system and hands over control of system operation to it.
To begin Setup, press the <Delete> key during boot-up before or while a message
similar to this appears briefly at the bottom of the screen during POST (Power On Self
Test):
Press DEL if you want to enter SETUP
If the above message disappears before you have responded and you still wish to enter
Setup, reboot the system to try again by pressing the “RESET” button on the system
case. You may also restart by simultaneously pressing the <Ctrl>, <Alt> and <Delete>
keys.
Press F1 to continue, DEL to enter SETUP

the F1 key again.
4.1.3 In Case of Problems
If after making and saving system changes with Setup, you discover that your computer
is no longer able to boot-up, the Award BIOS supports an override to the CMOS
settings that resets your system to its default configuration.
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. Your system
manufacturer has carefully chosen the Chipset defaults for the best performance and
reliability. Even a seemingly small change to the Chipset setup may cause the system
to become unstable.

4.2 Main Setup Menu
When you enter the Award BIOS CMOS Setup Utility, a Main Menu (Figure 1)
appears on the screen. The Main Menu allows you to select from several Setup
functions and two exit choices. Use the arrow keys to select among the items and press
Enter to accept and enter the sub-menu.

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, each time the system boots.
If you do not want to select drive type AUTO, other methods of selecting the drive type
are available:
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.
The following 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.

2.88M, 3.5 in 3-1/2 inch double-sided drive; 2.88 megabyte capacity
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 is not selected during Setup.
EGA/VGAEnhanced Graphics Adapter/Video Graphics Array. For EGA, VGA,
SEGA, SVGA or PGA monitor adapters.
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.
Halt on
During the “power-on self-test” (POST), the computer stops if the BIOS detect any
hardware errors. You can instruct 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 detect any non-fatal error, POST stops and
prompts you to take corrective action.
All, But keyboard
POST does not stop for a keyboard error, but stops for all
other errors.
All, But Diskette
POST does not stop for diskette drive errors, but stops for all
other errors.
All, But Disk/Key
POST does not stop for a keyboard or disk error, but stops for
all other errors.
43
Memory
Values in the Memory field cannot be changed and 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
Base Memory is typically 640 KB. It is also referred to as conventional memory.
The DOS operating system and conventional applications utilize this type of
memory.
Extended Memory
Extended Memory is 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.
Other Memory
Between 640 KB and 1 MB; which is often called High memory, DOS may load
Terminate-and-Stay-Resident (TSR) programs, such as device drivers, to free as
much conventional memory as possible for applications. Lines in your
CONFIG.SYS files that begin with LOADHIGH will load programs into high
memory.
Total Memory
System total memory is the sum of base memory, extended memory, and other
memory.

4.4 BIOS Features Setup Menu
This screen (Figure 3) contains industry-standard options additional to the core PC AT
BIOS. This section describes all fields offered by Award Software in this screen. Some
fields may vary from those in your Setup program. Your system board designer may
omit or modify some fields.
Virus Warning
When enabled, you will 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.
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.
Boot Sequence
The original IBM PCs loaded the DOS operating system from drive A (floppy disk).
Because of this, IBM PC-compatible systems are designed to search for an operating
system first on this drive, 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; as well as an
SCSI hard drive and a CD-ROM drive.
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.
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.
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.
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.
Typematic Rate (Chars/Sec)
When the Typematic Rate setting is Enabled, you can select a Typematic rate (the rate
at which characters repeat when you hold down a key) of 6, 8, 10,12, 15, 20, 24 or 30
characters per second.
Typematic Delay (Msec)
When the Typematic Rate setting is enabled, you can select a Typematic Delay (the
delay before keystrokes begin to repeat) of 250, 500, 750 or 1000 milliseconds.
Security Option
If you have set a password, select whether the password is required each time the
System boots, or only when you enter Setup.
PCI/VGA Palette Snoop
Some display cards that are not standard VGA such as graphics accelerators or MPEG
cards may not show the correct colors. This setting can correct the problem once it is
set to Enabled. For default setting leave at Disabled.
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.
46
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, an SCSI adapter.
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
hard-wire 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.

PCI IRQ Activated By
Leave the IRQ trigger set at Level unless the PCI device assigned to the interrupt
specifies Edge-triggered interrupts.
PCI IDE 2nd Channel
The IDE standard supports two channels (interfaces) with two devices on each. Enable
the second channel if your system has two PCI IDE connectors in use, either on the
system board or on expansion boards. Disable the second channel if a second IDE
connector is not present or not in use.
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.
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.

4.8 Integrated peripherals Menu
Internal PCI/IDE
The SiS 5598 chipset contains a PCI IDE interface that supports two IDE channels:
Primary (IRQ14) and Secondary (IRQ15). Each channel supports two IDE devices so
the system is capable of supporting a total of four IDE devices. Select Primary,
Secondary, or both to activate chipset IDE interface(s) installed on your system board.
IDE Primary/Secondary Master/Slave PIO
The four IDE PIO (Programmed Input/Output) fields allow you to set a PIO mode (0-4)
for each of the four IDE devices that the onboard IDE interface supports. Modes 0
through 4 provide successively increased performance. In Auto mode, the system
automatically determines the best mode for each device.
IDE Primary/Secondary Master/Slave UDMA
Ustra DMA/33 implementation is possible only if your IDE hard drive supports it and
the operating environment includes a DMA driver (Windows 95 OSR2 or a third-party
IDE bus master driver). If your hard drive and your system software both support Ultra
DMA/33, select Auto to enable BIOS support.
IDE Burst Mode
Selecting Enabled reduces latency between each drive read/write cycle, but may cause
instability in IDE subsystems that cannot support such fast performance. If you are
experiencing disk drive errors, try setting this value to Disabled. This field does not
appear when the Internal PCI/IDE field, above, is Disabled.

IDE Data Port Write
Selecting Enabled speeds up processing of drive reads and writes, but may cause
instability in IDE subsystems that cannot support such fast performance. If you are
experiencing disk driver errors, try setting this value to Disabled. This field does not
appear when the Internal PCI/IDE field, above, is Disabled.
IDE HDD Block Mode
Block mode is also called block transfer, multiple commands, or multiple sector
read/write. If your IDE hard drive supports block mode (most new drives do), select
Enabled for automatic detection of the optimal number of block read/writes per sector
the drive can support.
Onboard FDC Controller
Select Enabled if your system has a floppy disk controller (FDC) installed on the system
board and you wish to use it. If you install an add-in FDC or the system has no floppy
drive, select Disabled in this field.
