procedure is provided for logging onto the NEC Bulletin Board and obtaining the latest
Flash ROM BIOS.
Section 3, Options, provides safety precautions and installation procedures for installing
options.
Section 4, Maintenance and Troubleshooting, includes a list of NEC service information
and telephone numbers that provide access to the NEC Bulletin Board System (BBS),
FastFacts, and Technical Information Bulletins. Recommended maintenance information
and solutions to possible problems that may occur, are also provided.
Section 5, Desktop Repair, provides desktop disassembly and reassembly procedures
along with an illustrated parts breakdown. NEC service and spare parts ordering
information is also provided.
Section 6, Minitower Repair, provides minitower disassembly and reassembly procedures
along with an illustrated parts breakdown. NEC service and spare parts ordering
information is also provided.
Appendix A, Connector Pin Assignments, provides a list of the system board’s internal
connector pin assignments and a list of external pin assignments for the keyboard/mouse,
serial port, parallel port, and video port.

Each system incorporates power management features, and has factory installed software to
enhance the hardware features. Systems come with a dual operating system requiring that
either Microsoft®Windows for Workgroups™ or Windows 95™ be selected when the
system is first powered on.
The following paragraphs give an overview of the desktop and minitower systems.
Differences between systems are noted as they occur.

Technical Information 1-3
DESKTOP SYSTEM CHASSIS
The desktop 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.
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.

1-4 Technical Information
MINITOWER SYSTEM CHASSIS
The minitower chassis provides an enclosure for the system board, power supply, five
useable expansion slots, a six-connector PCI/ISA backboard, and seven storage device
slots. The expansion slots include three 8-/16-bit ISA slots, one shared PCI/ISA slot, and
one 32-bit PCI slot. For network-ready configurations, one slot has a network board
installed and the remaining slots are open.
The seven storage device slots accommodate up to four accessible devices and three
internal hard disk drive devices. The accessible devices include the standard one-inch high
3 1/2-inch 1.44-MB diskette drive and up to three 1.6-inch high 5 1/4-inch storage devices.
The internal device slots support up to three 3 1/2-inch hard disks; one in the standard front
slot. The other two install into a drive bracket that ships with the system. The bracket
attaches to the inside rear of the system.
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 three accessible 5 1/4-inch storage device
slots and two internal 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 two accessible 5 1/4-inch storage device
slots and two internal slots available for optional devices.
Figure 1-2 shows the front panel features and the locations of the accessible storage devices
in a minitower system. Multimedia systems come with a CD-ROM reader installed in the
top accessible device slot.
