Compatible Cyrix CPU Identification
The only Cyrix CPU that is supported on this motherboard is
labeled Cyrix 6x86 PR166+ but must be Revision 2.7 or later.
Look on the underside of the CPU for the serial number. The
number should read G8DC6620A or later.
5. Voltage Regulator Output Selection (VID0, 1, 2, 3)
These jumpers set the voltage supplied to the CPU. VID1 for 3.4V(STD) is
ignored, therefore, the jumper setting for 2.8V(Dual) may work for both
3.4V(STD) and 2.8V(Dual).
Intel Pentium (P54C)
(75MHz-200MHz)
Pentium MMX (P55C)
(150MHz-233MHz)
AMD-K6
(PR166 and faster)
AMD-K5
(PR75-PR133)

WARNING! Because CPU designs change rapidly, the following chart is only
intended as a simple quideline and is not intended to be true for your CPU.
Look for the CPU voltage included with your CPU and follow the Voltage
setting diagramed below the chart.
