Compatible Cyrix CPU Identification

The only Cyrix 6x86-PR166+ CPU that is supported on this
motherboard must be Revision 2.7 or later. Look on the un-
derside of the CPU for the serial number. The number should
read G8DC6620A or later.

9. Voltage Regulator Output Selection (DIP 1 – Switches 6, 7, 8, 9, 10)

These jumpers set the VCORE voltage supplied to the CPU. Switching regula-
tors allow some settings to be the same for two voltages of different power
planes.

WARNING!

Because CPU designs change rapidly, the table on the following

page is only intended as a simple guideline and thus may not be true for your
CPU. Always refer to the CPU documentation for your CPU’s voltage and then
set the appropriate VID jumpers according to the CPU Vcore Voltage Selection
illustration.
