3.12 VRM Installation

The VRM is required for the Pentium Pro to work. The CPU will program the VRM for the correct voltage needed. No jumper settings are needed, just install the VRM into the VRM socket nearest the CPU that is being installed. The VRM can only fit in the socket one way so there is no danger of installing it incorrectly. Not all VRM's will work in the S1668. Make sure you purchased a qualified VRM.
