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.
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 con-
sole show config command (described in Chapter 2). The table in Figure 4–16
maps the physical slot numbers to the SRM logical ID numbers for the back-
plane.
For information on restriction, see http://www.compaq.com/alphaserver/.
NOTE: To take advantage of 66 MHz, all modules in that hose must be 66 MHz
capable.
