2. INSTALLATION
2-1 Motherboard Layout
The motherboard is designed with Intel 82430VX, PCI
chipset which is developed by Intel Corporation to fully
support Pentium Processor PCI/ISA system. The chipset
provides an integrated IDE controller with two high
performance IDE interfaces for up to four IDE devices
(hard disk driver, LS-120 floppy driver, CD-ROM device,
etc). The ITE 8680/8687 Giga I/O controller provides the
standard PC I/O function: floppy interface, two 16Byte
I O serial ports and EPP/ECP capable parallel port. Care
must be taken when inserting memory modules, inserting
CPU or even plugging PCI card into associated slots to
avoid damaging any circuits or sockets on board. A
cooling fan is strongly recommended when installing
P54C/P54CTB/P55C/K5/6x86 due to possible overheat.
The motherboard supports minimum of 8MB of system
memory and a maximum of 128MB.
L2 Cache can be 256KB/512KB Pipelined Burst SRAM
onboard to increase system performance.
The motherboard supports standard ast Page( P),
EDO(Extended Data Out). The motherboard provides four
72-pins SIMM. The socket supports 4MB, 8MB, 16MB,
32MB, mixed each bank of memory upto 128MB. The
memory timing requires 70ns ast Page devices or 60ns
EDO RAM. Memory parity generation and checking is not
supported. (DRAM Modules may be parity (x36) or non-
parity (x32).
The board also supports Onboard two PCI IDE connectors,
and detects IDE hard disk type by BIOS utility automatic.
The system also supports Award Plug & Play BIOS for the
ISA and PCI cards.
