OCPRF100 MP Server System Technical Product Specification

Revision 1.0

entered by pressing F2 during POST. BIOS Setup is further described in Section BIOS Setup Utility.1

The iFLASH utility updates the system flash ROM. It provides security features that reduce the risk of tampering.

A recovery boot block allows recovery from catastrophic problems. The recovery boot block is electrically protected from erasure by a jumper on the OPRF100 I/O carrier.

6.1System Hardware

The OCPRF100 MP server system supports eight Pentium III Xeon processors. The Profusion PCIset connects these processors in a symmetric, cache-coherent configuration. The system supports a wide range of memory configurations from a minimum of 128 MB to a maximum of 32

GB.2 Four peer PCI buses provide high-speed access to resources in 10 hot-plug, 64-bit PCI slots.

For additional information about the chip set, see the Gemini External Design Specification and the PB64 External Design Specification. For additional board set information, see the OPRF100 MP Board Set Technical Product Specification.

6.1.1Processors

The BIOS supports eight-way symmetric multiprocessing (SMP) using the Pentium III Xeon processor and the Profusion PCIset. It automatically detects and initializes each processor. The BIOS permits mixed steppings of the processor. The flash ROM contains space for four

updates.3

BIOS supports the following processor features:

•Power-on Built-in Self-test (BIST)

•Processor bus error checking and correcting (ECC)

•Processor BIOS updates

•System management mode (SMM)

•Memory type range registers (MTRRs)

•Model specific registers (MSRs)

1.BIOS Setup should not be confused with the System Setup Utility (SSU), a DOS-based pro- gram that provides the means to specially configure adapter cards and various embedded devices. See the System Setup Utility External Product Specification for more information.

2.Support for 32 GB depends upon the commercial availability of the required DIMMs.

3.Although BIOS supports mixed steppings, uncharacterized errata may exist. Intel recommends using identical steppings because other configurations receive limited, if any, testing. The sys- tem BIOS does not support combinations that have known incompatibilities. Refer to the pro- cessor literature for further information about mixing processor steppings.
