     I need some information dealing with hardware and am at a lost to
finding the right source of information for finding it.

I own an 8088 ibm pc clone xt which is allegedly upgradable to 1 Meg
unfortunately I no longer own the manual and there-fore do not know
which jumpers to switch.

I put in the ram on and tried going through the combinations of pins 3-4 which 
normally select memory but nothing work. However, when i put the 64 K ram back 
I got errors I lost use of the 64K ram and therefore I have 512 K ram now

The motherboard has a sticker that says BESTEK on it and another sticker
that says SAN-8790606.

The 64K chips are aligned the same way as the 256K chips on the other two
banks which were not moved and the new set of 256 K chips have a notch
centered on the top and were also aligned the same way...

but it is possible that somehow I got confused and the bottom two
banks were originally facing the other direction.

This kind of an emergency situation and ALL help would be appreciated
from anyone who knows anything about xt motherboards w/ 1 meg or someone
who may possibly have the same motherboard.

thanks
