bridge). This function is used to meet latency of PCI
cycles to or from ISA bus. Try to enable or disable it,
if you have ISA card compatibility problem.

system reliability reason. However, this microcode
may slightly reduce CPU performance. We provide
this option for your convenience if you like to test it.

frequency while clearing CMOS or pressing "Home"
key. The default setting is 233 MHz, you can modify it
to match the actual CPU frequency by using the utility

This item is used to set clock spread spectrum for
EMI testing. Normally, you don't need to change the
default setting.
