P2 I/o ModES

The MVME5500 series supports two, jumper-configurable

P2 I/O modes: PMC mode and IPMC mode. PMC mode

is backward compatible with the MVME2300/

MVME2400 and MVME5100 in PMC mode. In PMC

mode, 64 pins from PMC slot 1 and 46 pins from PMC

slot 2 are available on P2 for PMC rear I/O. In IPMC

mode, the MVME5500 series supports legacy

MVME761 or MVME712M I/O modules (with limited

PMC I/O) when an IPMC761 or IPMC712 PMC card is

populated in PMC slot 1. In this configuration, PMC

slot 2 contains some signals that are reserved for extended SCSI.
