Motorola MVME5100, Single Board Computer manual Idsel Routing

Features Descriptions
This is accomplished by using the corresponding on-board IPMC712 or
IPMC761 connector to route the PCI/ISA Bridge interrupt signal to the
external interrupt 0 of the Hawk ASIC (MPIC).
Note The SCSI device on either the IPMC712 or IPMC761 uses the
standard INTA# pin J11-04 of PMC Slot 1.	4

IDSEL Routing

Legacy IDSEL assignment for the PCI/ISA Bridge is also maintained to ensure software compatibility between MVME5100 and the MVME2700 while in SBC mode (also called 761 or IPMC mode).

This is accomplished by using either the on-board IPMC712 or IPMC761 connector to route IDSEL (AD11) to the PCI/ISA Bridge on the IPMC712 or IPMC761.

Note The SCSI device on the IPMC712 and IPMC761 uses the

standard IDSEL pin J12-25 connected to AD16.

When a standard PMC card (not the IPMC712 or IPMC761) is plugged into slot 1, its IDSEL assignment corresponds to the standard IDSEL pin J12-25 and shall be connected to AD16.
