PCI bus information.
The “Slot” column lists the logical slots seen by the system. They are not
the physical slots into which devices are installed. See Table 2–1 for the
correspondence between logical slots and physical slots.
The NCR 53C896 on Hose 0, Bus 0 is a dual-channel Ultra2 SCSI
multifunction controller. Two controllers reside on the same chip. They
are shown as 2/0 and 2/1. The first number is the logical slot, and the
second is the function.
The Acer Labs bridge chip, which is located in PCI logical slot 7, has two
built-in IDE controllers. The CD-ROM is on the first controller.
NOTE: The naming of devices (for example,dqa.0.0.15.0) follows the
conventions described in Table 2–2.
