5)Manual CPU Ratio Settings (DSW Switches 5-10)

Set DSW switches (5-10) to use the clock multiplier to coordinate the ratio of bus speeds with CPU settings. Set the DSW switches according to the internal speed of your processor and the bus frequency (133/100MHz).

IMPORTANT:

1. To use this feature, JEN must be set to Jumper Mode, [1-2]. (See 1, JumperFree™ Mode (JEN) in 3, HARDWARE SETUP.)

2. Ensure the DSW settings are correct:

DSW switch 10 is OFF to disable the manual CPU ratio settings. DSW switch 10 is ON, for all manual CPU ratio settings.
