XMI Private Space
References to XMI private space are serviced by resources local to a node,
such as local device CSRs and boot ROM. The references are not broadcast
on the XMI. XMI private space is a 24-Mbyte address region located from
E000 0000 to E17F FFFF.
XMI Nodespace
The VAX 6000 platform XMI nodespace is a collection of 16 512-Kbyte
regions located from E180 0000 to E1FF FFFF. Nodes 0 and F are not
implemented. Each XMI node is allocated one of the 512-Kbyte regions
for its control and status registers. The starting address of the 512-Kbyte
region associated with a given node is computed as follows:
E180 0000 + (Node ID x 80000)
