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 IBM Personal Computer models come with a SCSI adapter. For information on locating the riser card, see "Locating Components" on page 11. The riser card in your computer has three ISA slots and three PCI slots. These slots are dedicated to either the ISA or PCI bus. The following illustration shows the expansion slots on the riser card. Note: The diskette and IDE drive connectors are also on the riser card. When installing optional drives, refer to the two illustrations below for the location of the appropriate connectors.
