Memory Sockets & Modules
There are six memory module sockets on the mainboard. Two
are for 168-pin DIMM memory modules. The DIMM sockets
function independently of each other. The other four sockets are
for 72-pin SIMM memory modules. The SIMM sockets are paired
into two ‘banks.’ This means you must install two modules at a
time to fill one bank. You cannot use DIMM and SIMM modules
at the same time on this mainboard.
This mainboard has a very flexible memory design that al-
lows the use of a variety of memory options up to a total of
384MB. There is more information about this in Adding System
Memory section of Section 3: Reconfiguring Your Mainboard.
CPU Socket & CPU
The Socket 7 CPU socket supports the full range of Pentium
®
-
class CPUs including MMX Pentiums
®
. Installing a CPU in the
socket is easy. The lever at the side of the socket latches the CPU
in place when it is down and releases it when raised.
If you want to install a CPU upgrade or are installing a CPU
on the board for the first time, please refer to ‘Installing a CPU’ in
Section 3: Reconfiguring Your Mainboard.
Port & Controller Connections
There are several ports and connectors on the mainboard. Some
are external ports and others are internal connectors that connect
to other parts of the computer or internal options.
External Ports
This mainboard has several external ports including the COM1
and COM2 serial ports, a Parallel port, dual USB ports and PS/2-
type keyboard and mouse ports. All but the keyboard and mouse
ports use external port brackets which mount in expansion card
slot openings and attach to connectors on the mainboard. These
external ports are all accessible at the rear of the computer when
the mainboard is installed.
