4.1
UNPACKING
The system board package should contain the following parts :
The PT-5IVL system board.
OPERATION MANUAL.
Cable set for IDE and I/O device.
4.2
HARDWARE CONFIGURATION
Before the system board is ready to operate, the hardware must be configured to allow for various functions
within the system. To configure the PT-5IVL system board is a simple task, only a few jumpers, connectors,
cables and sockets needs to be selected and installed. (For the detailed locations of each component please refer
to the "system board layout figure" which appears in page 3-1.)
4.2.1 DRAM INSTALLATION
The PT-5IVL system board will support two banks main memory (bank 0 and bank 1) on board (using four 72-
Pin SIMM socket, SIMM 1-4), each bank could be single-sided or double-sided, 8MB up to 128 MB of local
memory can be attained. Supports both standard fast page mode (FPM) and Extended Data Out (EDO) memory.
(
Note that this system board doesn't support 3.3V SDRAM
) The speed of FPM DRAMs must be used 70ns or
faster than 70ns, the speed of EDO DRAMs must be used 60ns or faster than 60ns.
The usable SIMM modules are :
(Note : S = Single-sided , D = Double-sided)

Bank can be populated in any order (bank 0 does not have to be populated before bank 1). Within any given
bank, the SIMMs must be the same size. Among the two banks, SIMM densities can be mixed in any order.
EDO and FPM can be mixed between SIMMs, a given SIMM must contain only one type of DRAM. When
DRAM types are mixed each SIMM runs optimized for that particular type of DRAM.
