100Mhz Cpu Host Frequency Force Selector: Jp7; 133Mhz Cpu Host Frequency Force Selector: Jp10; Clear Cmos Select: Jp4 - TMC TI6NBF+ User Manual

Chapter 4 Configuring the Motherboard

4.2 100MHz CPU Host Frequency Force Selector: JP7

The TI6NBF+ is able to detect the host frequency (66MHz or 100MHz)
of the installed CPU. The JP7 jumper, however, can be set to
override the detection and force the host frequency to run at 100MHz.

The JP10 jumper on the TI6NBF+ motherboard is the 133MHz CPU
Host Frequency Force Selector. When it is short, the host frequency
(bus speed) is auto detected by the system. When it is open, the host
frequency is set to 133MHz. The 133MHz forced setting applies only to
the TI6NBFV+ motherboard that uses the VIA Apollo Pro Plus chipset.
When JP10 is open, both the CPU and memory implements 133MHz
frequency. The memory module used should therefore be PC133
compatible. With a motherboard integrating the Intel 440BX AGPset,
setting JP10 to OPEN will have no effect, because the host frequency has
been fixed to 100MHz during shipment.

4.4 Clear CMOS Select: JP4

Use JP4, a 3-pin header, to clear the contents of the CMOS RAM. Do not
clear the CMOS RAM unless it is absolutely necessary. You will lose
your password, etc. To clear CMOS, the ATX-power connector should
be disconnected from the motherboard
