Introduction  
Unpacking the Mainboard  
The mainboard package contains:  
¥ The EQ82C661X Mainboard  
¥ This UserÕs Guide  
Note: Do not unpack the mainboard until you are ready to install it.  
Follow the precautions below while unpacking the mainboard.  
1. Before handling the mainboard, ground yourself by grasping an  
unpainted portion of the systemÕs metal chassis.  
2. Remove the mainboard from its anti-static packaging and place it on  
a grounded surface, component side up.  
3. Check the mainboard for damage. If any chip appears loose, press  
carefully to seat it firmly in its socket.  
Do not apply power if the mainboard appears damaged. If there is  
damage to the board contact your dealer immediately.  
Electrostatic Discharge Precautions  
Make sure you ground yourself before handling the mainboard or other  
system components. Electrostatic discharge can easily damage the  
components. Note that you must take special precaution when handling  
the mainboard in dry or air-conditioned environments.  
Take these precautions to protect your equipment from electrostatic  
discharge:  
¥ Do not remove the anti-static packaging until you are ready to install  
the mainboard and other system components.  
¥ Ground yourself before removing any system component from its  
protective anti-static packaging. To ground yourself grasp the  
expansion slot covers or other unpainted portions of the computer  
chassis.  
¥ Frequently ground yourself while working, or use a grounding strap.  
¥ Handle the mainboard by the edges and avoid touching its  
components.

Introduction

Remarks on the Cyrix and IBM P200+ CPUs  
Please note that if you use a Cyrix or IBM P200+ CPU, you will have to set the  
frequency to 75MHz. You will also have to set JP16, the PCI bus frequency  
jumper to asynchronous to have the PCI bus run on 32MHz, in order to avoid  
problems with add-on cards. If you choose to run the PCI bus on a higher  
frequency, please use only high-end add-on cards that are specified to function  
on higher bus frequencies. Please note that using a 75MHz bus clock also places  
higher demands on the DRAM main-memory, therefore only use high-end  
SIMM/DIMM modules when this is the case.  
Voltage settings list  
Jumpers 30, 31 and 32 set the processor voltage. If you are using a single voltage  
processor close jp31 and open jp30. Jp31 shorts the processor Vcore voltage pins  
to the Vio pins when closed. If you use a dual voltage CPU, open jp31 and close  
jp30.  
Jp 32 sets the voltage, please refer to the following table:

2 Hardware Setup  
This chapter is designed for Normal edition mainboard use only and it  
explains how to configure the mainboardÕs hardware. After you install  
the mainboard, you can set jumpers, install memory on the mainboard,  
and make case connections. Refer to this chapter whenever you upgrade  
or reconfigure your system.  
CAUTION: Turn off power to the mainboard, system chassis, and  
peripheral devices before performing any work on the  
mainboard or system.

If default I/O port addresses conflict with other I/O cards (e.g. sound cards  
or I/O cards ) , you must adjust one of the I/O addresses to avoid address  
conflict. (You can adjust these I/O addresses from the BIOS)  
Note: Some sound cards have a default IRQ setting for IRQ7, which  
may conflict with printing functions. If this occurs do not use sound  
card functions at the same time you print.  
Connectors  
Attach the mainboard to case devices via connectors on the mainboard. Refer to  
Figure 1-1 for connector locations and connector pin positions.  
COM1, COM2 – COM1/COM2 Connectors

Video Off Option  
Susp, Stbyoff:Video off when the system

Video Off Method Choose V/H Sync+Blank (default), Blank  
screen, or DPMS for the selected PM mode.  
Conserve Mode  
Use the default setting.  
HDD Power Down When the set time has elapsed, the BIOS sends a  
command to the HDD to power down, which  
turns off the motor. Time is adjustable from 1 to  
15 minutes. The default setting is Disabled.  
Some older model HDDs may not support this  
advanced function.  
Doze Mode  
When the set time has elapsed, the BIOS sends a  
command to the system to enter doze mode  
(system clock drops to 33MHz). Time is  
adjustable from 10 seconds to 1 Hour.  
Suspend Mode  
The default is Disabled. Only an SL-Enhanced  
(or SMI) CPU can enter this mode. Time is  
adjustable from 10 seconds to 1 Hour. Under  
Suspend mode, the CPU stops completely (no

NONE to disable the power management timer.

DMA/master  
Choose On (default) to enable the power  
management timer, or Off to disable the power

Choose Off (default) or On. If you choose the  
system ÒOffÓ, will not monitor the signal of  
DMA/master; and when you choose ÒOnÓ, the  
system will not have SMI signal until the master  
is finished while the master is working.  
Primary INTR  
IRQ#  
When On (default) is chosen, you can choose  
any IRQ #.  
When set at ÒPrimaryÓ the processor will power  
down only after the BIOS detects a Òno IRQ  
activityÓ during the time specified by the  
Suspend time. If set at ÒSecondary eventÓ the  
system will distinguish whether an interrupt  
accesses and I/O address or not. If it does, the  
system enters the standby mode. If not, the  
system enters the dreaming mode; that is the  
system goes back full-on status but leaves the  
monitor blank. For instance, if the system  
connects to a LAN and receives an interrupt  
from its file server, the system will enter the  
dreaming mode to execute the corresponding  
calling routine.

Jumper for Cyrix/IBM CPU (J100)  
The SY-5EAS mainboard has a new jumper (J100) for better  
performance with Cyrix/IBM CPUs. Here is explaination  
for you on how to use this jumper correctly.  
l Leave J100 open when you want to install a non-Cyrix  
/IBM CPU (default setting), or short J100 when you want to  
install a Cyrix CPU.  
If you use a Cyrix/IBM CPU, do the following steps :  
(1) Press [DELETE] to enter BIOS setup menu during boot-up.  
(2) Select “ Chipset Features Setup ”  
(3) Set “Linear Burst” to “Enabled” then choose “SAVE &  
EXIT SETUP”
