The following table shows the Vendor ID and the Device ID for each of the planar PCI devices
on the MVME4100.
4.11.2 PCI Arbitration Assignments
The integrated PCI/X arbiters internal to the PLX PCI6520 provide PCI arbitration for the
MVME4100.
The arbitration assignments on the MVME4100 are shown in the next table so that software
may set arbiter priority assignments if necessary.
