The OptiPlex GX1/GX1p and OptiPlex NX1 systems are equipped with an integrated diskette drive controller (PIIX4e) that can support a maximum of two non-EIDE diskette and tape drives via a 34-pin DSKT connector located on the system board. The low-profile chassis can accommodate only one external drive device (diskette drive or tape drive). Other chassis configurations can accommodate two external drive devices. NOTES: If the diskette drive and tape drive are both attached to the diskette drive controller on the system board, only the diskette drive is configured in the System Setup program as Diskette Drive A or Diskette Drive B. The tape drive is then listed as Not Installed (under either the Diskette Drive A or Diskette Drive B option). The OptiPlex NX1 system contains an integrated controller and diskette drive connector, but is not equipped with a diskette drive. If you run the diskettebased diagnostics, this computer requires an external diskette-drive kit as described in Chapter 2, "Basic Troubleshooting." The OptiPlex GX1/GX1p and OptiPlex NX1 systems include an integrated high-performance 64-bit accelerated graphics port (AGP) subsystem, implemented on the system board, which drives an external SVGA monitor. The AGP contains a dedicated bus that bypasses the PCI bus and allows for interconnection of the video subsystem directly to the Pentium chip set for the extra-high performance required for 3D video subsystems. This architecture also off-loads the PCI bus, providing greater performance for devices attached to the PCI bus. The maximum supported resolution is 1600 x 1200 with 65,535 colors at 75 Hz. The SVGA subsystem consists of the following major components: ATI RAGE PRO TURBO video controller 4-MB synchronous graphics random-access memory (SGRAM) video memory (expandable to 8 MB via a video-memory upgrade kit); 8 MB standard on the GX1p 15-hole monitor port The integrated audio controller is a single chip that connects to the ISA bus. The audio controller has analog jacks for line-in and microphone input. The single line-out output jack provides stereo output for a line-level input to an external amplifier or drives stereo headphones. See "Technical Specifications" found later in this chapter for audio jack input and output specifications. System Overview 1-5

The OptiPlex GX1/GX1p and OptiPlex NX1 systems are equipped with an inte-

grated diskette drive controller (PIIX4e) that can support a maximum of two

non-EIDE diskette and tape drives via a 34-pin DSKT connector located on the

system board. The low-profile chassis can accommodate only one external

drive device (diskette drive or tape drive). Other chassis configurations can

accommodate two external drive devices.

NOTES: If the diskette drive and tape drive are both attached to the diskette

drive controller on the system board, only the diskette drive is configured in

the System Setup program as

Diskette Drive A

Diskette Drive B

. The tape

drive is then listed as

Not Installed

(under either the

Diskette Drive A

Diskette Drive B

option).

The OptiPlex NX1 system contains an integrated controller and diskette drive

connector, but is not equipped with a diskette drive. If you run the diskette-

based diagnostics, this computer requires an external diskette-drive kit as

described in Chapter 2, “Basic Troubleshooting.”

The integrated audio controller is a single chip that connects to the ISA bus.

The audio controller has analog jacks for line-in and microphone input. The

single line-out output jack provides stereo output for a line-level input to an

external amplifier or drives stereo headphones. See “Technical Specifications”

found later in this chapter for audio jack input and output specifications.
