VT8501 Main Board 1
Chapter 1 Introduction
1-1 The Main Board Overview
The main board is designed based on VIA chipset, “VT8501 & VT82C686A,” which
provides a high-performance/cost index desktop solution for the Intel® Pentium®
P54C/P55C. AMD® K5/K6/K6-2(K6-III is under test), Cyrix® M1/6x86L/MX/MII/, and
other compatible Pentium® processors with 3D A.G.P. VGA system. The integrated
H/W 3D VGA controller adopts 64-bit 100MHz host bus speed and shares 2MB,
4MB, or 8MB from frame buffer memory with system which improves the
performance eminently.
The main board integrated PCI-mastering dual full-duplex direct-sound AC97-
link-compatible sound system. Hardware soundblaster-pro and hardware-assisted
FM blocks are included for Windows DOS box and real-mode DOS compatibility.
Loopback capability is also implemented for directing mixed audio stream into
USB and 1394 speaker for high quality digital audio.
The main board also implements high performance I/O Controller utilizes with
fully Plug and Play device which supports 2.88 MB Floppy, Dual 16550
Compatible (with 16 bytes FIFO, up to 460K baud rate) Serial Port, ECP
(Enhanced Capabilities Port), EPP (Enhanced Parallel Port) parallel port, Infrared
IrDA (HPSIR), and Amplitude Shift Keyed IR. (ASKIR) port.

VT8501 Main Board 2
The main board supports three 32-bit PCI & two 16-bit ISA for highest
performance I/O add-on adapter cards. The system board supports 4 PCI bus-
mastering slots (PCI 2.2 compliant) and allows synchronous CPU and PCI bus
clock frequency. The main board is also strengthened with Power Management
Wake up events like “Modem ring on,” which are the new inventions to enable
PCs to be turned on over the network or modem. These are also key benefits in
PC operation, new system setup and power conservation.
In conclusion, the main board is a combination of the highest in performance,
flexibility, efficiency, and ease of use that meets a variety of price/performance
levels. The main board is an ideal platform for the increasing requirements of
today’s and future’s desktop application.

2-3 Jumper Settings
There are 6 jumpers on this main board. Different setups have different functions.
The following pages will tell how to set the jumpers under different circumstances.
2-3-1 JP1: Single CPU Voltage Selector
JP1 is a 2-pin selector to choose CPU with 3.45V VIO, such as AMD®K6-PR300
2.2/3.45V. Set to “1-2” for 3.45V VIO, and “off” for 3.3V VIOs.

VT8501 Main Board 13
2-3-2 JBAT1: CMOS Status
JBAT1 is a 3-pin connector. Clear CMOS if system password is forgotten. Below
is details to show how to clear CMOS.
Procedure to clear CMOS:
Step 1: Shut down the system and disconnect the power supply from AC power.
Step 2: If the system uses AT/ATX power, pull out the AT/ATX cable from power
connector.
Step 3: Short the CMOS jumper by putting jumper cap on Pin 2-3 for a few seconds.
Step 4: Set JBAT1 to “off” to return normal setup.
Step 5: Link power cable to the connector & connect AC power to power supply.
Step 6: Turn on system power.
If you’d like to set password, press “DEL” Key during system bootup to enter
CMOS setup and establish a new password.

VT8501 Main Board 14
2-3-3 JP3: PS/2 Mouse Selector
JP3 is a 3-pin jumper providing PS/2 mouse function. Set “2-3” if the system uses
P/S2 mouse, and “1-2” without PS/2 mouse.
