introduction
MVE488
Board
made simply by running a program. With the MVE486
there are no chassis to open, no jumpers to set.
Simply run a DOS program that reads a BIOS
file
and then programs the new BIOS into the FLASH
memory chip.
Note:
This is an option, that depending
upon your source, a
BIOS may or may not be
installed. To determine whether a FLASH BIOS is
installed, examine location U67 on the left hand lower
edge of the board. If installed device occupies all
available pins of the socket, it is a FLASH part. If two
rows of pins are empty, then the MVE486 is equipped
with a standard EPROM BIOS.
Frequency Synthesizer:
Selecting a processor
speed is as simple as setting a couple of jumpers.
There are no oscillators to purchase, no components
to desolder and resolder. The clear benefit of this
feature is the ability to select whatever processor
speed desired. However, DX2 or
proces-
sors (known as clock doublers), with a maximum input
clock frequency of 33-MHz may be run on any stand-
ard board.
