The following shows the connection of processor memory modules (PMMs) for A1080a-E model.
Some processor memory modules cannot be connected one another or some I/O controllers
(IOHs) cannot be connected to processor memory modules directly, but can be connected via
other processor modules.

Example) In the eight-processor memory module configuration, PMM1 and IOH3 cannot be
connected directly as shown below. However, a PCI card under IOH3 can be used via
PMM5 or PMM3,PMM8 and PMM7.
For example, the PCI card under IOH3 can be used via PMM3,PMM8 and PMM7
even in the case of failure on either PMM5.
* PMMx is an abbreviation of a processor memory module.
* IOHx is an abbreviation of an I/O hub.
* ICH is an abbreviation of an I/O control hub.
