Pci Slot Voltages And Hose Numbers - Compaq AlphaServer ES45 Service Manual

The PCI slots are split across four independent 64-bit PCI buses, three buses at
66 MHz and one bus at 33 MHz. These buses correspond to Hose 0 through
Hose 3 in the system logical configuration. The slots on each bus are listed
below.
Some PCI options require drivers to be installed and configured. These options
come with a floppy or a CD-ROM. Refer to the installation document that came
with the option and follow the manufacturer's instructions.
There is no direct correspondence between the physical numbers of the slots
on the I/O backplane and the logical slot identification reported with the SRM
console show config command (described in Chapter 2). The table in Figure
6–7 maps the physical slot numbers to the SRM logical ID numbers for the
10-slot backplane.
