ClearPath Dorado 300/400/700/800/4000/4100/4200 Server I/O ...

PCI-Based I/O Hardware
All of the I/O slots in the Internal I/O Module in the Dorado 800 are PCI-X 133MHz. In
the Remote I/O Module, only three of the I/O slots are PCI-X 133MHz, the remaining
three slots are PCI-X 100MHz. The SIOP-M requires the highest bandwidth. The
configuration rules for the Dorado 800 must assign the SIOP-M first to the 133MHz
PCI-X buses and then use the 100MHz PCI-X buses.
For more information on the PCI-card slot assignments, see Section 1.3.3 I/O
Expansion Module (Internal or External) for the Dorado 800.
The IOP logical number to PCI-card slot assignments are the same in the Internal I/O
Module and the Remote I/O Module due to the software configuration based on the
PCI assignments. To keep the configurations the same for Internal I/O Modules or
Remote I/O Modules, the same rules are utilized for the Host card assignments.
