INTRODUCTION
The Baby AT SI19 mainboard is a high-performance personal computer
mainboard. This mainboard supports Intel®Pentium®processor/Pentium®
processor with MMXTM technology,Cyrix®6x86/6x86L/6x86MX,and AMD®
K5/K6 processors. The mainboard also supports three 32-bit PCI (Periph-
eral Component Interconnect) Local Bus standard slots.
The mainboard uses the highly integrated SiS®5591 chipset to support the
AGP/PCI/ISA and Green standards, and to provide the Host/AGP bridge.
The SiS®5591 chipset integrates all system control functions such as ACPI
(Advanced Configuration and Power Interface). The ACPI provides more
Energy Saving Features for the OSPM(OS Direct Power Management)
function. The SiS®5595 chipset also improves the IDE transfer rate by
supporting Ultra DMA/33 IDE that transfer data at the rate of 33MB/s. In
addition to this, it also offers hardware monitor function as an optional
function.

HARDWARE INSTALLATION
2.1 Central Processing Unit: CPU
The Baby AT SI19mainboard operates with Intel® Pentium®processor/
Pentium®processorwith MMXTMtechnology,Cyrix® 6x86/6x86L/6x86MX
and AMD® K5/K6 processors. It could operate with 2.1V to 3.5V proces-
sors. The mainboard provides a 321-pin ZIF Socket 7 for easy CPU
installation, a switch (SW1/SW2) to set the proper speed for the CPU. The
CPU should always have a cooling fan attached to prevent overheating.

3. Press the lever down to
complete the installation.
2. Locate Pin 1 in the socket
and look for the white dot or
cut edge in the CPU. Match
Pin 1 with the white dot/cut
edge. Then, insert the CPU.
It should insert easily.

To adjust the speed and voltage of the CPU, you must know the specifica-
tions of your CPU (always ask the vendor for CPU specifications). Then
refer to Table 2.1 (Intel® processors),Table2.2 (Cyrix® processors)and
Table 2.3 (AMD® processors)for proper setting.

Cyrix® processor uses PR to rate the speed of their processors based on
Intel® Pentium®processor core speed. For example PR150 (120MHz) has
150MHz core speed of Intel®Pentium®processor but has 120MHz core
speed in Cyrix®processor. Cyrix® processor should always uses a more
powerful fan (ask vendor for proper cooling fan).
