Introduction
The 82430VX motherboard is a high performance system
hardware based on the Intel Pentium¨
processor and is
equipped with four PCI slots, four standard ISA slots, Super
Multi I/O controller, and dual ports PCI IDE connectors for
future expansion. The hardware dimension is 220mm x
280mm with four layer design technology.

2
Features
¥ Supports Intel Pentium¨ /P55C, AMD K5 CPU at 75 ~
166 MHz, and Cyrix 6x86(L)/M2 CPU at P120+~ P166+
MHz on a ZIF Socket 7
¥ Intel 82430 VX chipset, PCI 2.1 compliant
¥ Supports dual USB ports
¥ Supports SDRAM 3.3V/Unbuffered Type (Optional)
¥ Supports 256K/512K write back cache with Pipeline
Burst SRAMs
¥ Supports up to 128 MB DRAM (Min. 4MB) onboard and
BIOS AUTO SPM/EDO/SDRAM DRAM table free
configuration
¥ Supports two independent high performance PCI Bus
Master IDE interface
¥ Supports four 32 bits master PCI slots, four 16 bits ISA
slots, and an jumperless PCI INT# Control Scheme
¥ 1 floppy port, 1 parallel port (EPP, ECP port), and 2 serial
ports (16550 Fast UART compatible)
¥ Supports PS/2 mouse connector
¥ Supports Award Plug & Play BIOS with Flash Memory
¥ Supports CPU Hardware Green function.
¥ Supports Infrared interface (optional)
¥ Supports 120MHz IDE Floppy and SCSI Boot function.
Note: Make sure that the SDRAM module not only has to be
168 pin DIMM but designed for 3.3V SDRAM as well.
Double check with the SDRAM supplier before install
any SDRAMs. The mainboard manufacturer has no
obligation to any damage of the board by using the
incorrect specification of SDRAM.

Chapter 2
Hardware Setup
This chapter includes sections of setting up jumpers on the
motherboard, the system memory configuration, the cache
memory configuration, and attaching the connectors. Refer
back to this chapter when you need to upgrade or
reconfigure your system and remember to turn off the
power of the system as well as all peripheral devices before
performing any work on the system.
Symbols used in this chapter are described below:
For 2-pin jumper:
Ð Close the jumper by inserting the jumper
cap over the two pins of the jumper.
Ð Open the jumper by removing the
jumper cap.
For 3-pin jumper:
123
Ð Close pins 1 and 2 with an jumper cap.
123
Ð Close pins 2 and 3 with an jumper cap.
