6. JP23 FSB/PCI Clock Ratio
8. Connecting IDE and Floppy Cable
9. Connecting Front Panel Cable
The JP23 is used to specify the relationship of PCI and FSB clock. Generally speaking, if
you are not overclockers, we recommend you to set the jumper at the default setting.
Connect 34-pin floppy cable and 40-pin, 80-wire IDE cable to floppy connector FDC and
IDE connector. Be careful of the pin1 orientation. Wrong orientation may cause system
damage.
