VIA 693/693A Twin Processor Mainboard
AWARD BIOS SETUP
4-10
CPU Host/ PCI Clock:
(default setting: “Default” )
This selection field is used to decide the CPU FSB clock. Basically, this mainboard
is designed by Intel VIA 693/693A AGPset and it supports both the 100MHz and
66MHz FSB frequency. When you select “default” setting, the system BIOS will
detect the CPU type and decide the FSB clock automatically. You may also use this
field to select different FSB clock and force your CPU to run at higher speed. ( be
sure to make sure your system devices are fast enough before you can change to
such setting)
When you have decided the FSB clock, you will have to use toggle switch (SW)
setting to select the CPU clock ratio and decide the CPU speed. please refer to page
3-23 for details of the switch settings..
Beside the "Default" FSB selection, this mainboard also provides the manual
option for your choice. You may use th "Page Up" and "Page Down" to select
different FSB clock, the FSB selectable in the BIOS are: 66, 75, 83, 100, 103, 112,
124, 133 and 140 MHz.
Note:
1. The higher FSB frequency will surely give you the higher
system performance. However, it is not recommended because
it may cause the system unstable, especially the component
like DRAM, HDD, Add on card is not fast enough.
2. Wrong selection of FSB clock may cause the PC system
hangup and the system can not boot, In case that it should be
happened, please use JP9 to clear the CMOS so that you can
