The RM performs the following steps:
1. Scans logical addresses (0 to FF) and identifies all devices in
VXIbus Mainframe #1. Finds the VXI-MXI-2 interfaces at logical
addresses 2 and 4 and moves DC devices to the lowest unused
logical addresses (for example, 1, 3, 5, 6).
2. Enables the logical address window of the VXI-MXI-2 found at
logical address 2 for the entire outward mapping range of 0 to FF.
Scans all logical addresses, skipping all previously encountered
devices, and finds the VXI-MXI-2 in VXIbus Mainframe #3, the
VXI-MXI-2 in VXIbus Mainframe #2, MXIbus Device A, and
MXIbus Device B.
3. Enables the logical address window of the VXI-MXI-2 in VXIbus
Mainframe #3 for the entire inward mapping range of 0 to FF.
Scans all logical addresses, skipping all previously encountered
devices, and finds the VXI-MXI-2 at logical address 82. Finds the
Slot 0 device and uses it to move all DC devices in VXIbus
Mainframe #3 to the lowest unused logical addresses (for example,
81, 83, 84, 85).
