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.

Introduction
K7VM400M series of mainboards utilize VIA KM400+VIA
8235 or 8237 chipset, providing a fully compatible, high per-
formance and cost-effective mATX platform. The new inte-
grated technologies, together with AC’97 audio(2/6-
channel), 6 USB 2.0, 2 SATA(with 8237 only), and ATA133/
100/66/33, give customers an advanced, multimedia solu-
tion at reasonable price. It provides 200/266/333MHz host
bus speed to support AMD Athlon/Athlon XP/Duron socket
A processors and the DDR200/266/333 memory. It also pro-
vides advanced features such as Wake up by USB devices,
Wake-on-LAN, Wake-on-Modem(optional) and Keyboard
Password Power-on functions. Suspending to RAM, the op-
timal implementation of the Advanced Configuration and
Power Interface (ACPI) specification, makes the PC’s power
consumption drop to the lowest possible level and enable
quick wakeup.

The Line-in jack can be connected to devices such as a cassette or minidisc player to playback or
record. The Microphone-in jack can be connected to a microphone for voice input. The Speaker-
out jack allows you to connect speakers or headphones for audio output from the internal amplifier.
6-Channel Audio
This mainboard utilizes VT1616 chip 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 connected to the Front speskers, the
Back Left&Right jack can be connected to the rear speakers and the Center&Woofer jack can be

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.
ATX Power Supply Connector & Power Switch (POWER SW)
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.
If you change “Soft-off by PWR-BTTN” from default “Instant-off” to
“Delay 4 Sec” in the “POWER MANAGEMENT SETUP” section of
the BIOS, the power switch should be pressed for morethan 4
seconds before the system powers down.

Wake-Up On LAN (WOL1)(available on -L mainboard)
Through the Wake-Up On LAN function, a wake event occurring from the network can wake up
the system. If this function is to be used, please be sure an ATX power supply and a LAN
adapter which supports this function are used. Then connect this header to the relevant con-
nector on the LAN adapter, set “Power on by Ring/LAN” as Enabled in the “POWER MAN-
AGEMENT SETUP” section of the CMOS SETUP. Save and exit, then boot the operating
system once to make sure this function takes effect.
Wake-Up On Internal Modem (WOM1)(optional)
Through this function, the system which is in the suspend or soft-off status can be waked up by
a ring signal received from the internal modem. When this function is used, be sure an internal
modem card which supports this function is used. Then connect this header to the relevant
connector on the modem card, set “Power on by Ring/LAN” as Enabled in the “Power Manage-
ment Setup” section of the CMOS SETUP. Save and exit, then boot the operating system once
to make sure this function takes effect.
