P2 Input/Output (I/O) Modes

The MVME5100's on-board memory and optional memory mezzanines
allow for a variety of memory size options. Memory size can be 64 or
512MB for a total of 1GB on-board and mezzanine ECC memory. The
memory is controlled by the hardware which provides single-bit error
correction and double-bit error detection (ECC is calculated over 72-bits).
Either 1 or 2 mezzanines can be installed. Each mezzanine will add 1 bank
of SDRAM memory of 256MB. A total of 512MB of mezzanine memory
can be added.
The MVME5100 has two P2 I/O modes (761 and PMC) that are user-
configurable with jumpers on the board. The jumpers route the on-board
Ethernet port 2 to row C of the P2 connector.
761 mode is backwards compatible with the MVME761 transition card
and P2 adapter card (excluding PMC I/O routing) used on the
MVME2600/2700. 761 mode is accomplished by configuring the
on-board jumpers and attaching an IPMC761 PMC Card in PMC slot 1 of
the MVME5100.
PMC mode is backwards compatible with the MVME2300/MVME2400.
PMC mode is accomplished by simply configuring the on-board jumpers.
