This chapter describes the configuration guidelines that must be followed prior to adding a Pentium Pro processor as well as detailed procedures on removing and installing processor modules.

  • Page 138: Configuration Guidelines

    Processor Module Upgrades Processor Compatibility in a Multiprocessor Environment DIGITAL recommends using identical steppings/versions of processors within a multiprocessor system whenever possible, since these configurations have received the greatest amount of validation testing. Since it is not possible to validate every combination of processor steppings, each new stepping of a processor is fully validated only against the latest stepping.
