2.5 – Force 33MHz Click for PCI Bus 2 (JP13)
1 2 Closed: All devices on PCI Bus2 (slots J35 and onboard SCSI) will run at 33MHz
Only.
Open (default): PCI Bus1 can run at 66MHz or 33MHz. Actual speed is determined
by the PCI card plugged into J33. If any card is only 33MHz capable, all cards in Bus1
will run at 33MHz. If all cards support 66MHz, or if no cards are installed, then Bus1
will run at 66MHz.
2.6 – Host Bus (FSB) Clock Frequency Select (JP5)
1
2
Closed: Host Bus clock frequency is fixed at 100 MHz, regardless of processor type.
Use this setting to force Host Bus clock to 100 MHz when using 133 MHz FSB
CPU(s).
Open (default): Host Bus clock frequency is determined by the type of processor(s)
installed. For CPUs that support 133 MHz Front Side Bus (FSB), Host Bus clock will
be automatically set at 133 MHz, but can be over-ridden to 100 MHz if JP5 is closed.
For CPUs that are only capable of operating at 100MHz FSB, Host Bus frequency will
be auto-configured to 100MHz, and 133 MHz is NOT possible.
2.7– CPU Core-to-Bus Frequency Multiplier Select (JP1-4)
These jumpers allow you to adjust the processor core multiplier. However, retail processors will
not allow multiplier adjustment.

4.0x is the default setting.
Note: Whatever the multiplier is set to, the setting will apply to both CPUs. These settings only
affect non-retail (engineering sample, Q-spec) CPUs. For a production (S-spec) CPU, the
multiplier is fixed inside the CPU, and these jumpers will not have any affect regardless of their
setting.
