When you look at properties for a device node of a PCI device, you will see a few properties that are unique to PCI devices and a few properties that have a different format than that of a SBus device. For example, the output of .properties for a PCI device:
ok cd /pci@1f,4000/scsi@3 ok .properties target6-scsi-options 00 00 05 f8 target5-scsi-options 00 00 05 f8 target4-scsi-options 00 00 05 f8 target3-scsi-options 00 00 05 f8 target2-scsi-options 00 00 05 f8 target1-scsi-options 00 00 05 f8 latency-timer 00000011 assigned-addresses 81001810 00000000 00000400 00000000 00000100 82001814 00000000 00010000 00000000 00000100 82001818 00000000 00011000 00000000 00001000 device_type scsi-2 fru motherboard clock-frequency 02625a00 reg 00001800 00000000 00000000 00000000 00000000 01001810 00000000 00000000 00000000 00000100 02001814 00000000 00000000 00000000 00000100 02001818 00000000 00000000 00000000 00001000 model Symbios,53C875 compatible 70 63 69 31 30 30 30 2c 66 00 67 6c 6d 00 70 63 name scsi devsel-speed 00000001 class-code 00010000 interrupts 00000020 max-latency 00000040 min-grant 00000011 revision-id 00000014 device-id 0000000f vendor-id 00001000
The following example shows generic names for devices under /pci@1f,4000/scsi@3:
