Menu III.
NOTE
When you enable Soft Menu III, all DIP switches must be set to OFF.

AGP Frequency
The DS9 lets you set the frequency ratio between AGP clock and the Front Side Bus (CPU
Bus). Generally, if you set the CPU FSB clock to 66MHz, you ought to set this switch to
“OFF (1/1)”. If you set the CPU FSB clock to 100Mhz or higher, you ought to set this switch
to “ON (2/3)”
