Caution
Caution
Be sure to add some Silicone Grease between the CPU and the
heatsink to keep them fully contacted to meet the heat sink require-
ment.
Be sure to unplug the AC power supply before adding or re-
moving expansion cards, RAM or other system peripherals, other-
wise your mainboard and RAM might be seriously damaged.

This manual is suitable for mainboards of K7S746FX. Each

Introduction
K7S746FX mainboards utilize ( SIS 746FX + SIS 963/963L) chipset
providing a fully compatible, high performance and cost-effective
ATX platform. The new integrated technologies, together with AGP
8X support, AC’97 audio(2/6-channels), integrated LAN(optional),
6 USB 2.0 ports, 2 DRR 400 slots, 2 IEEE 1394 ports (optional),
and 2 SATA connectors(optional), give customers an advanced,
multimedia solution at reasonable price. It provides 200/266/
333MHz host bus speed to support AMD socket 462 processors
and the largest DDR memory capacity is up to 2GB. It also pro-
vides advanced features such as Wake-on-LAN, AntiVirus function,
ACPI function and so on. The optimal implementation of the Ad-
vanced Configuration and Power interface (ACPI) specification
makes the PC's power consumption drop to the lowest pos-
sible level and enable quick wakeup.

This mainboard utilizes ALC655chip providing 6-channel Audio, which consists of Front
Left, Front Right, Rear Left, Rear Right, Center and Woofer for a complete surround
sound effect. When 6-Channel audio is available, the front Left&Right jack can be con-
nected to the Front speakers, the Back Left&Right jack can be connected to the rear speak-
ers and the Center&Woofer jack can be connected to the center speaker and woofer.
Microphone function is offered by Microphone In or F_AUDIO Connector on the mainboard
If set 2-Channel Audio mode on -6A or -6AL mainboard, you can connect two speakers to
the Front Left&Right jack, at the same time use the Rear Left&Right jack as Line in jack, and
use the Center&Woofer jack as Microphone in jack.

ATX Power Supply Connector & Power Switch (POWER SW)
Be sure to connect the power supply plug to this connector in its proper orientation.
The power switch (POWER SW) should be connected to a momentary switch. When
powering up your system, first turn on the mechanical switch of the power supply (if
one is provided), then push once the power switch. When powering off the system, you
needn’t turn off the mechanical switch, just push once the power switch.
Hard Disk LED Connector (HD_LED)
The connector connects to the case’s IDE indicator LED indicating the activity status
of IDE hard disk. The connector has an orientation. If one way doesn’t work, try the other
way.
Reset Switch (RESET)
The connector connects to the case’s reset switch. Press the switch once, the system
resets.
If you change “Power Button Override” from default “Instant-
off” to “Delay 4 Sec” in the “POWER MANAGEMENT SETUP”
section of the BIOS, the power switch should be pressed for
more than 4 seconds before the system powers down.
