PCI Bus Numbering in a Microsoft Windows NT Environment
Appendix D, Order of Detection for Retired
Compaq ProLiant Servers
Table 18 lists the PCI bus detection order, Primary and Secondary bus locations, and slot
numbers for the several retired ProLiant servers. This matrix can help you identify how the PCI
BIOS assigns bus numbers in these servers. The ProLiant 2500 servers consist of the bridged PCI
Bus architecture, and all of the others are dual-peer PCI Bus architecture servers. In reviewing
this matrix, you will see that there are differences in the PCI bus number detection order from one
server model to another.
