Adapters and the Riser Card Your computer uses a riser card for expansion. The riser card contains expansion slots that connect adapters to the industry standard architecture (ISA) and peripheral component interconnect (PCI) buses. You can install a variety of adapters in the expansion slots on the riser card. Some models come with an IBM-installed SCSI adapter. For information on locating the riser card, see "Locating Components" on page 9. The riser card in your computer has two ISA slots and three PCI slots. The third PCI connector from the top shares a slot with the ISA connector directly below it. The other slots are dedicated to either the ISA or PCI bus. You can install only one adapter in the shared slot. The following illustration shows the expansion slots on the riser card.

Adapters and the Riser Card
Your computer uses a riser card for expansion.
The riser card contains expansion
slots that connect adapters to the industry standard architecture (ISA) and
peripheral component interconnect (PCI) buses.
You can install a variety of adapters in the expansion slots on the riser card.
Some
models come with an IBM-installed SCSI adapter.
For information on locating the
riser card, see “Locating Components” on page
9.
The riser card in your computer has two ISA slots and three PCI slots.
The third
PCI connector from the top shares a slot with the ISA connector directly
below
it.
The other slots are dedicated to either the ISA or PCI bus.
You can install only one
adapter in the shared slot.
The following illustration shows the expansion slots on the riser card.
