JP1: Clear CMOS Jumper
This jumper enables you to reset BIOS:
1. Turn the system off.
2. Short pins 2 and 3 on jumper 1.
3. Return the jumper to the normal setting.
4. Turn the system on. The BIOS is returned to the de-
fault settings.
JP3: BIOS Flash Protection Jumper
Set the jumper to disabled if you are going to update your
BIOS. After updating the BIOS, return it to the default setting
(enabled). For instructions on updating the BIOS refer to
Chapter 3.
JP4: Onboard CODEC/AMR Slot Selection
This jumper is used to enable either the onboard codec or the
AMR slot codec (AMR1).
JP5: AMR Master/Slave Select Jumper
This jumper is used to distinguish the AMR codec from the
onboard AC 97 codec to avoid conflict.
JP6: CPU Frequency Select Jumper 1
This jumper is used to force a CPU clock running at 66 MHz
FSB to run at 100 MHz FSB. It is recommended that you
leave the jumper on the normal setting.
JP7: CPU Frequency Select Jumper 2
This jumper is similar to JP6 and is used to force a CPU clock
running at 100 MHz FSB to run at 133
MHz FSB
. It is recom-
mended that you leave the jumper on the normal setting.
Note:
The CPU speed is determined by the CPU Host/PCI
Clock speed multiplied by the CPU Clock Ratio.
Refer to the Frequency Control Option in Chapter 3
for more information. Also note that Forcing the
CPU to run at a higher clock speed then it was rated
for is called overclocking and is not recommended.
