INTRODUCTION
The MICRO ATX AL14 mainboard is a high-performance personal computer
mainboard. This mainboard supports Intel® Pentium® processor/Pentium®
processor with MMXTM technology, AMD®K6/K6-2/K6-III, and Cyrix®
6x86L/6x86MX/MII processors. This mainboard combines leading edge
AGPATI®3D 128VRtechnologyingraphicsandCreative®ES1373PCI
Enhanced technology in audio. The mainboard also supports three 32-bit
PCI (Peripheral Component Interconnect) Local Bus standard slots.
The mainboard uses the highly integrated Aladdin® 5 chipset to support the
PCI/ISA and Green standards, and to provide the Host/AGP bridge. The
Aladdin® 5 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 Aladdin® 5 chipset also improves the IDE transfer rate by
supporting Ultra DMA/33 IDE that transfer data at the rate of 33MB/s.

HARDWARE INSTALLATION
2.1 Central Processing Unit: CPU
TheMICROATXAL14mainboard operateswithIntel®Pentium® processor
withMMXTM technology,AMD®K6/K6-2/K6-III,andCyrix®6x86L/
6x86MX/MIIprocessors. It could operate with 2.0V to 1.3V processors.
The mainboard provides a 321-pin ZIF Socket 7 for easy CPU installation, a
DIP switch (SW1) to set the proper speed for the CPU and (JV1) for setting
the CPU voltage. It is recommended that the processor should have a
cooling fan attached to prevent from 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.

SW1 CPU
1. The DIP Switch SW1 (4, 5, & 6) is used to adjust the CPU clock frequency.
2. The DIP Switch SW1 (1, 2, and 3) is used to set the Core/Bus (Fraction)
ratio of the CPU. The actual core speed of the CPU is the Host Clock
Frequency multiplied by the Core/Bus ratio. For example:
If CPUClock = 66MHz
Core/Busratio = 3/2
then CPUcore speed = Host Clock x Core/Bus ratio
= 66MHz x 3/2
= 100MHz

To set the proper speed and voltage of the CPU, you must know the specifi-
cations of your CPU (always ask the vendor for CPU specifications).
Then refer to Table 2.1 (Intel®Processor), Table 2.2 (Cyrix®
Processor), and Table 2.3 (AMD®Processor) for proper setting.
