CHAPTER 2 HARDWARE INSTALLATION Chapter 2 HARDWARE INSTALLATION 2.1 Central Processing Unit: CPU The ATX AL9 mainboard operates with Intel® Pentium®processor with MMXTM technology, Cyrix®6x86L/6x86MX, and AMD®K6/K6-2/K6-III processors. It could operate with 2.1V to 3.5V processors. The mainboard provides a 321-pin ZIF Socket 7 for easy CPU installation, a jumper switch (S1) to set the proper speed for the CPU and (S2) for setting the CPU voltage.
CHAPTER 2 HARDWARE INSTALLATION 2.1-2 CPU Core Speed Derivation Procedure 1. The Jumper S1 (4, 5 & 6) is used to adjust the CPU clock frequency. 4 5 6 CPU Clock 0 0 0 100 0 0 1 75* 0 1 0 83 0 1 1 66 1 0 0 95 1 0 1 68 1 1 0 75** 1 1 1 60 * AGP = 60/PCI =30 ** AGP = 75/PCI = 37.
CHAPTER 2 HARDWARE INSTALLATION 2. The Jumper S1 (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 CPU Clock Core/Bus ratio then CPU core speed = = = = = 66MHz 3/2 Host Clock x Core/Bus ratio 66MHz x 3/2 100MHz 1 2 3 CPU 0 0 0 1.5/3.5 0 1 0 3x 1 0 0 2x 1 1 0 2.5x 0 0 1 5.5x 0 1 1 5x 1 0 1 4x 1 1 1 4.

CHAPTER 2 HARDWARE INSTALLATION Table 2.2 Cyrix® Processor Cyrix® 6x86 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 it has120MHz core speed in Cyrix®processor. Cyrix® 6x86 processor should always use a more powerful fan (ask vendor for proper cooling fan). a.
