The KM266-MNB Mainboard
Page 41
Auto Detect DIMM/PCI Clk
When “Enabled” is selected, the mainboard will detect the presence of devices
on DIMM and PCI slots. When there is no device present on some of the PCI or
DIMM connectors, the clock on the related DIMM and PCI slot will be disabled
to reduce the Electro-Magnetic Interference (EMI).

CPU Clock
This field allows a timing combination for the CPU to be selected. There is a
large range of possible combinations (+/- 1MHz to 132MHz). If Default is se-
lected the BIOS will use the clock values for the CPU card.
CPU / AGP / PCI Skew Adjust
The Skew Adjust fields allow you to insert clock delays between the system
and the devices (e.g. CPU, AGP or PCI). The purpose of the adjustment is to
improve the stability of a mainboard system. Skew is defined as the time be-
tween the earliest and latest signal arrival at the destination, the unit used by
Skew adjust is measured in PicoSeconds (PS). The selectable options for the
filed are 500PS, 1000PS, 1500PS and Disabled.
Normally the option of each Skew Adjust filed will automatically detect by the
system depends on what type of CPU, AGP card and PCI interface you installed
in the mainborad. If you happen to use different option in the field and the
mainboard cannot boot up properly, in order to let the mainboard to boot up
again you may clear the BIOS CMOS(
