Expansion with Adapters
By installing optional adapters, you can expand the capabilities of your computer
and take advantage of a variety of peripheral devices and applications. Your
computer has a riser card for connecting adapters to the ISA or PCI bus. Examples
of adapters that can be added to your computer include graphics, SCSI (small
computer system interface), and NIC (network interface controller) adapters.
High-Capacity Hard Disk Drives
Some PC models come with a hard disk drive that has an enhanced integrated drive
electronics (EIDE) bus-master interface. The EIDE drive plugs into one of two EIDE
connectors located on the riser card in your computer. You can connect an
additional hard disk drive to the ribbon cable already attached to the riser card, or
you can purchase another cable and connect up to two hard disk drives or other
IDE or EIDE devices to the second connector on the riser card.
Notes:
1. A maximum of three internal IDE or EIDE devices can be installed—limited by
the number of available bays.
2. For models with an IBM factory-installed CD-ROM, two ribbon cables (for
connecting IDE or EIDE devices) are shipped with your computer.
Other PC models come with an ultra-wide SCSI hard disk drive that has a small
computer system interface (SCSI) interface. These PC models have a PCI SCSI
adapter installed in one of the expansion slots. If your computer has an
IBM-preinstalled SCSI adapter, refer to the SCSI documentation provided with your
computer for information on the adapter and for instructions on installing SCSI
devices.
CD-ROM Drive
A CD-ROM drive is installed in some PC models. CD-ROM (compact disc
read-only memory) technology offers quick access to enormous amounts of
information. A compact disc can store more than 650 MB of data, such as the large
files needed for audio, still and full-motion video, and still and animated graphics.
A CD-ROM drive can play back or read from a CD, but it cannot write information
on it.
