SYSTEM CHASSIS
The system chassis provides an enclosure for the system board, power supply, four
expansion slots, a five-connector PCI/ISA backboard, and four storage device slots. The
expansion slots include two 8-/16-bit ISA slots, one dedicated 32-bit PCI slot, and one
shared PCI/ISA (32-bit PCI or 8-/16-bit ISA) slot. For network-ready configurations, one
slot has a network board installed and the remaining slots are open. For multimedia
configurations without a network board, all slots are open. For multimedia configurations
with a network board, one slot has a network board and the remaining slots are open.
The four storage device slots accommodate up to three accessible devices and one internal
hard disk drive device. The accessible devices include the standard one-inch high 3 1/2-
inch 1.44-MB diskette drive and up to two 1.6-inch high 5 1/4-inch storage devices. The
non-multimedia hard disk systems ship with an accessible 3 1/2-inch diskette drive and an
internal 3 1/2-inch hard disk drive, leaving two accessible 5 1/4-inch storage device slots
available for optional devices. The multimedia systems ship with an accessible 3 1/2-inch
diskette drive, an internal 3 1/2-inch hard disk drive, and an accessible 5 1/4-inch CD-
ROM reader, leaving one accessible 5 1/4-inch storage device slot available for an optional
device.
Figure 1-1 shows front panel features and locations of the accessible storage devices in a
desktop system. Multimedia systems come with a CD-ROM reader installed in the top
accessible device slot.
