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 on 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 mainboard carton for obvious damage. Shipping and handling may cause
damage 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 damage.
Press down on all of the socket IC's to make sure that they are properly seated. Do this only
on with the board placed on a firm flat surface.
M
Do not apply power to the board if it has been damaged..
You are now ready to install your mainboard. The mounting hole pattern on the mainboard
matches the IBM-XT system board. It is assumed that the chassis is designed for a
standard IBM XT/AT mainboard mounting.
Place the chassis on the anti-static mat and remove the cover. Take the plastic clips, Nylon
stand-off and screws for mounting the system board, and keep them separate.
