Hardware Installation
This chapter provides information on how to use the jumpers and
connectors on the SBC8153 in order to set up a workable system.
3.1 CPU Installation
The SBC8153 Industrial CPU Card supports a ZIF processor socket
for Pentium-level processors.
Unlike PGA sockets, ZIF (Zero Insertion Force) sockets come with a
lever to secure the processor. Make sure the notch on the corner of
the CPU corresponds with the notch on the inside of the socket.
After you have installed the processor into the ZIF socket, check if the
jumpers for the CPU type and speed are correct.
NOTE:
Ensure that the CPU heat sink and the CPU top surface are in
total contact to avoid CPU overheating problem that would
cause your system to hang or be unstable.
3.2 Memory Installation
The SBC8153 Industrial CPU Card supports four 72-pin SIMM sockets
for a maximum total memory of 256MB. The DRAMs (5Volts) for the
SIMM sockets can be 4MB, 8MB, 16MB, 32MB, and 64MB in EDO
and FPM types.
The following should be noted when populating the SIMM sockets:
1. SIMM1/SIMM2 and SIMM3/SIMM4 should consist of the
same size SIMMs.
SIMM1/SIMM2 and SIMM3/SIMM4 should consist of the
same type SIMMs. For example, SIMM1 and SIMM2 are
both be EDO or Page Mode.
