9) CPU External Frequency Setting (DSW-1, -2, -3, -4, -5)
This option tells the clock generator what frequency to send to the CPU and the
PCI bus. This allows the selection of the CPU’s External frequency.
IMPORTANT:
1. In JumperFree mode, all dip switches (DSW-1–DSW-5) 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.
NOTE: If your processor does not have a locked Frequency Multiple, you must
use CPU Core:Bus Freq. Multiple in 4.4 Advanced Menu of the BIOS setup to
set the Frequency Multiple. If the Frequency Multiple is locked, setting the Fre-
quency Multiple in BIOS setup will have no effect.
