Chapter 1
Introduction
The PCI PENTIUM SI3 All-In- ne system board is a high-
performance personal computer system board based on a 3.3V
version of the PentiumÔ microprocessor ¾ the P54C
microprocessor. The system board supports the Peripheral
Component Interconnect (PCI) Local Bus standard with a 188-pin
PCI/ISA BUS riser slots.
A cache subsystem can be configured for 256K, 512K or 1M
cache memory to improve overall throughput.
The system board uses the highly integrated SIS 551X chipset to
support the PCI/ISA and 32-bit Enhanced PCI IDE. The ATI
mach64 and WINB ND W83787/W83768 provide all other on-
board peripherals.

Cache Size and Memory
Locations
The system board supports 256K, 512K, and 1M of cache
memory. You can configure the cache memory in the following
two ways:
1. Install 32K8 or 64K8 SRAM chips in Data RAM
sockets U2 - U9.
2. Install 8K8, 16K8, or 32K8 SRAM chips in Tag
socket U27.

Chapter 2 ¾ Installation
Cache Selection: JS1, JS2
You can then set jumpers JS1 and JS2 as shown in the table
below. Note that the speed required for SRAM chips is 15ns.

µ § 1. Tag RAM (U27) uses 128AK.
2. Tag RAM (U27) uses 129AK.
µ § All Data SRAM used on the system board are special
SRAM that use 5 volts for power input. However, all
other I/O pins use 3.3 volts level for access interface.
Suitable SRAM include:
1. WINB ND W24M257AK-15 (32K8 mixed
mode)
2. WINB ND W24M512AK-15 (64K8 mixed
mode)

4. WINB ND W24257AK-15 (32K8)
5. WINB ND W24M257AK-15 (32K8)
Memory Bank Configuration
The system board supports four memory banks and provides four
72-PIN, single in-line on-board memory module (SIMM) sockets,
numbered SIMM1 ¾ SIMM4.
Each socket accepts single density or double density (D)SIMM in
the following sizes: 4M(S), 8M(D), 8M(S), 16M(S), 32M(D),
64M(S), and 128M(D).
You can use one piece of 72 PIN SIMM (32 bits DRAM) in
SIMM1 or SIMM3.
The maximum memory configuration is: 512M=SIMM1/2 (128M
x 2) + SIMM3/4(128Mx2)
µ § You must install two of the same type of EDO or FP in
the SIMM sockets SIMM1/SIMM2 or SIMM3/SIMM4
when you mix the EDO and fast page DRAM. For
example:
SIMM1 SIMM2 SIMM3 SIMM4

ED ED FP FP
FP FP ED ED

Serial Port
Connector:COM1,COM2
The system board provides two 9-pin male serial port connectors.
The interrupt request of C M1 is fixed to IRQ4. Interrupt of
C M2 and the selection of I/ ports (3F8,2F8,3E8,2E8) can be
set by BI S SETUP program. Please refer to chapter 3 -
Peripheral Setup.
Parallel Port Connector: PRN
The system board provides a standard 25-pin female connectors.
The printer port also supports Enhanced Parallel Port (EPP) and
Extended Capabilities Port (ECP).

Case Connector Block: JFP
The Turbo LED, Turbo Switch, Hardware Reset, Keylock, Power
LED, Sleep Switch, Speaker and HDD LED all connect to the JF
Connector Block as shown below. See figure 1-1 for JF’s
location.
Figure 2-4: Case Connector Block - JF.
Power Supply Connector: J 1
The power supply connector is a twelve-pin male connector. Dual
connectors from the power supply can fit in only one direction.
