2. Board Installation.
2.1 Unpacking
The mainboard package should contain the following
* The S1462 Mainboard
* User's Manual
* ECU User's Manual
* EISA CFG. Utility Diskette
The mainboard contains sensitive electric components which can be easily
damaged by static electricity, so the mainboard should be left in its original
packing until it is installed.
Unpacking and installation should be done in a grounded anti-static mat.
The operator should be wearing an anti-static wristband, grounded at the
same point as the anti-static mat.
Inspect the main board carton for obvious damages. Shipping and handling
may cause damages to your board. Be sure there are no shipping and
handling damages on the board before proceeding.
After opening the mainboard carton, extract the system board and place it
only on a grounded anti-static surface component side up. Again inspect the
board for damages. Press down on all of the socket IC's to make sure that
they are properly seated. Do this only with the board placed on an anti-
static mat.
DO NOT APPLY POWER TO THE BOARD IF IT HAS BEEN
DAMAGED!
MAKE SURE THAT THE POWER SUPPLY IS CONNECTED
TO THE PROPER 5V CONNECTOR!

2.2 Installation
You are now ready to install your mainboard. The mounting hole pattern on
the mainboard matches the IBM-AT system board. It is assumed that the
chassis is designed for a standard IBM XT/AT mainboard mounting.
Place the chassis of the anti-static mat and remove the cover. Remove the
plastic clips, Nylon stand-off and screws for mounting the system board,
and keep them separately.

3.2 DRAM Installation
The mainboard can be installed with 1/2/4/8/16/32/64 MB 72 pins/70 ns
DRAM SIMM module. The DRAM memory system consists of 4 banks
(0-3). Each bank requires 2 SIMM modules to achieve 64 bit bus transfer
and proper operation. The total memory size can be from 2MB to 512MB.
Various DRAM configurations are shown on the table following this page.
