This appendix describes some information that is different in this PCI-bus-based system than in an Sbus-based Sun system.

The banner output is as follows, indicating that it is a PCI-based system by showing "UPA/PCI" in banner

Note that the output of show-devs command shows some PCI- based nodes. Also, PCI-based systems use generic names for devices. On-board network is named "network", and internal disks are named " diskn ", n representing the scsi target number for that disk.

Plug in PCI cards with their own FCodePROM may or may not be using generic names. For details on generic names, see Recommended Practices available on homepage for Open Firmware Working Group at:

The following shows the output of the devalias command on the Sun Ultra 5/10 UPA/PCI system:

The command .speed shows the speed for the processor and busses attached to the system:

The Sun Ultra 5/10 UPA/PCI system has two PCI busses, pcia & pcib . The probing of slots for those busses are controlled by the following two NVRAM configuration variables.
