Mainboard User’s Manual
For this mainboard, you must use 168-pin, 3.3V unbuffered
SDRAM memory modules. If the installed CPU uses a 100MHz
system bus, you must use PC100 or PC133 memory; if a 66MHz
system bus, you must use PC66 memory. You can install any size
memory module from 16 MB to 512MB, so the maximum memory
size is 2 x 512MB = 1GB.
Edge connectors on the memory modules have cut outs coinciding
with spacers in the DIMM sockets that memory modules can only
be installed in the correct orientation.
To install a module, push the retaining latches at either end of the
socket outwards. Position the memory module correctly and insert
it into the DIMM socket. Press the module down into the socket so
that the retaining latches rotate up and secure the module in place
by fitting into notches on the edge of the module.
Setting Jumper Switches
Jumpers are sets of pins connected together with caps. Jumper caps
change the way of mainboard’s operation by changing the
electronic circuits on the mainboard. If a jumper cap connects two
pins, we say those pins are SHORT; if the cap is removed, they are
OPEN.
