CHAPTER 2
HARDWARE INSTALLATION
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). This
mainboard uses two different Clock Generator, so before adjusting SW1,
check your clock generator. Then refer to Table 2.1 (Intel

processor/Pentium

technology), Table 2.2
(Cyrix
®
6x86/6x86L/6x86MX processor) and Table 2.3 (AMD
®

processor) for proper setting.

Note: The table provided can be used by both clock generator. The only
difference with the ICS9148-04 and IMI643 Clock Generator is the
CPU clock frequency of 50, 55, 83 MHz. Since these 3 frequencies
are not supported by the current CPUs, so the jumper settings for
both regulator are the same.
