^It does not matter how these jumpers are set. For P54C, AMD K5, and Cyrix 6x86
CPUs, VC1 and VC2 are set to OFF, making the VID0-VID3 settings, which are only
active if VC1 and VC2 are ON, irrelevant. The VID0-VID3 settings for the Cyrix 6x86L
series will vary. Some of the CPUs in this series are 2.8V, and others are 3.3V. Check the
face of the CPU and the CPU Voltage Settings table for the proper settings for these
jumpers.
