Jumper settings and functions

WARNING:

All jumper settings should be done with the PC off and the power disconnected.

VGA interrupt selection (VIRQ) and VGA setting (VEN_DIS)

Jumpers for adjusting the on-board video.

Setting the VIRQ and VEN_DIS jumpers over pins 2-3 enables the VGA port.

Setting the VIRQ and VEN_DIS jumpers over pins 1-2 disables the VGA port (use this setting when installing a video card).

Figure 3: VIRQ and VEN_DIS jumper settings

Audio line out settings

Leave these jumpers set to disabled if Audio connectors are not present on the motherboard.

Jumper pins 3-5 and pins 4-6 of LINEOUT_SW if you are using speakers that require a powered signal (sound quality signal will be less).

Jumper pins 1-3 and pins 2-4 of LINEOUT_SW if you are using speakers that are powered.

Jumper pins 2-3 of AUDIOEN to enable audio (do not enable if there are no audio connections on the motherboard).

Jumper pins 1-2 of AUDIOEN to disable the motherboard audio.

Figure 4: LINOUT_SW and AUDIOEN jumper settings

Keyboard power (wake) up (KB_UP)

Jumper pins 1-2 of KB_UP to disable wake-on-keyboard power save feature.

CPU Speed setting

1 - CPU bus frequency jumpers

2 - CPU bus frequency multiply jumpers

Jumpers set the clock generator that the CPU and chipset read. These jumper settings set the CPU external frequency (or BUS Clock) and settings will result in higher or lower processor speeds.

CAUTION:

Setting a speed rating higher than a processor is rated can damage the processor.

Figure 6: 1. CPU bus frequency jumpers

1 - CPU frequency

2 - Memory frequency - SDRAM

3 - PCI frequency

CPU bus frequency multiply jumpers

These jumpers set the frequency ratio between the internal frequency of the CPU and the external frequency (called the BUS Clock) within the CPU. These must be set together with the above jumpers CPU external (BUS) frequency selection.

CAUTION:

Setting a multiplier rating to create a freuency that is higher than a processor is rated can damage the processor.

Figure 7: CPU to BUS frequency ratio jumper settings

1 - BF - Bus frequency jumper

2 - CPU A - AMD-K62, AMD-K6

3 - CPU B - Intel Pentium P54C, AMD-K5

4 - CPU C - Intel Pentium P55C, IBM/Cyrix 6x86MX, IBM/Cyrix M II

5 - CPU D - IBM/Cyrix 6x68, IBM/Cyrix 6x86L

Voltage regulator output selection (VID0, VID1, VID2, VID3)

These jumpers set the VCORE voltage supplied to the CPU. Switching regulators allows some jumper settings to be the same for two voltages of different power planes.
