Install Memory
The mainboard has three DIMM sockets for system memory
modules. You must install at least one memory module in order to
use the mainboard.
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. You can
install any size memory module from 8 MB to 256MB, so the
maximum memory size is 3 x 256MB = 768MB.
The edge connectors on the memory modules have cut outs, which
coincide with spacers in the DIMM sockets so 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 which can be connected together with
jumper caps. The jumper caps change the way the mainboard
operates by changing the electronic circuits on the mainboard. If a
jumper cap connects two pins, we say the pins are SHORT. If a
jumper cap is removed from two pins, the pins are OPEN.
