4. CPU External (BUS) Frequency Selection (FS0, FS1, FS2)
These jumpers tell the clock generator what frequency to send to the CPU. These
allow the selection of the CPU's External frequency (or BUS Clock). The BUS Clock
times the BUS Ratio equals the CPU's Internal frequency (the advertised CPU speed).
5. CPU to BUS Frequency Ratio (BF0, BF1)
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.
Set the jumpers by the Internal speed of the Intel, AMD, or Cyrix CPU as follows:

*Cyrix 166+
133MHz
*NOTE: Only Cyrix Revision 2.7 or later is supported on this motherboard. See previous page for
revision identification. Bootup screen will show 6x86-P166+ -S CPU at 133MHz with the
Cyrix 166+ installed on this motherboard.

Compatible Cyrix CPU Identification

The only Cyrix CPU that is supported on this motherboard is
labeled Cyrix 6x86 P166+ but must be Revision 2.7 and later.
Look on the underside of the CPU for the serial number. The
number should read G8DC6620A or larger.
