3.1 How to Find a Register in XMI Address Space
Because XMI addresses correspond to slot and node numbers, you want to
determine the slot of the XMI card cage in which the module resides. The
slot number can be determined in two ways:
• By looking at the XMI card cage (numbering of slots is shown in
Figure 3–1)
• By entering at the console a SHOW CONFIGURATION command
A typical response is shown below.
>>> SHOW CONFIGURATION

1+ KA65A (8080) 0006
2+ KA65A (8080) 0006
6+ MS65A (4001) 0084
7+ MS65A (4001) 0084
8+ MS65A (4001) 0084
9+ MS65A (4001) 0084
B+ DEMNA (0601) 0003
C+ KDM70 (0C22) 0001
E+ DWMBB/A (2002) 0002

1+ DWMBB/B (2107) 0007
4+ DMB32 (0109) 210B
6+ TBK70 (410B) 0307
Assume that you want to examine the Bus Error Register (XBER) of the
DEMNA module in slot 11, which is XMI node B. From Table 3–1, XMI
Nodespace Addresses, you can see that the nodespace base address for the
XMI module at node B is E1D8 0000. From Table 6–2, XMI Required
Registers, you can see that the XBER offset is BB + 04, so you add 04 to
the base address to get the address for that module’s XBER register. You
could examine the XBER register with the command:
>>> E/L/P E1D80004
