3. HARDWARE SETUP

3) CPU External Frequency Setting (SW1)

This option tells the clock generator what frequency to send to the CPU, DRAM,
AGP, and the PCI bus. This allows the selection of the CPU’s External fre-
quency.

IMPORTANT:

1. In JumperFree mode, all dip switches must be set to OFF.
2. When JumperFree mode is enabled, use BIOS setup in place of these switches

(see CPU Speed in Advanced Menu in BIOS Setup).

NOTE: Only selected switches are illustrated. For a complete frequency listing,
see next page.
