PCI Option Modules
Figure 2–14 shows a typical PCI option module and is for reference only.
Note that the PCB is fastened to the opposite edge of the bulkhead bracket
than an ISA option. Thus, the PCI option components in PCI slot 3 (J25)
occupy the same space that the ISA option in ISA slot 1 (J24) would
occupy, making the slots mutually exclusive.
