Introduction
System Board
Overview
General Description:
The MVE486 is a Baby AT
form factor
system board based upon the
Intel 80486 series CPU. The highly integrated
design provides high performance coupled with a long
list of features including: 4 bus master
slots, 2
EISA-VL
bus master slots,
and future upgrade processor support, up to
of direct-map adaptive write-back cache, up to
128MB of DRAM, integrated
for serial, parallel,
IDE and high speed floppy drive control, FLASH ROM
BIOS,
(Zero Insertion Force) CPU socket and
frequency synthesizer. A brief description of major
feature follows:
BUS Architecture:
has emerged as the
defacto standard for a 32-bit PC BUS. Backward
compatible with the original AT BUS, as well as pro-
viding the highest performance available from a PC
standard bus 33
is the architecture
of choice, All slots on the MVE486 are “Bus Master”
and “Burst Mode” compatible ensuring
adapter
compatibility.
VESA Bus Architecture:
VESA emerged as the
facto standard local bus for PC systems. VESA-VL
bus works at
so the highest data transfer
rates can be achieved. MVE486 supports two VESA
slots up to speeds of
Both the slots are bus
master, non-DMA slots.
CPU:
The MVE486 includes a special
ZIF (Zero Insertion Force) socket that allows easy
processor changes. The MVE will handle the full
spectrum of the i486 series of processors from the
through the
as well as
the available speeds of the
and the new
processors. Installation of a processor is
easy with the special
(Zero Insertion Force)
socket; simply lift the tension
remove the old
CPU and drop in the new processor. There are no
special tools required. A series of jumpers are clearly
marked to select the processor type.
