Dell 3000 manual PS/2 Mouse, IDE Controller, FDD Controller, CD-ROM Drive Speed, Plug & Play O/S

PS/2 Mouse

The default setting is Enabled. Select Disabled when you want to attach a serial mouse to the computer.

NOTE: Before connecting or disconnecting a PS/2 mouse, turn off your computer. After you connect a PS/2 mouse and turn your computer back on, the external mouse is automatically detected and the touch pad is disabled.

IDE Controller

Enables the integrated local-bus IDE adapter. Available options are Both (the default), Disabled, or Primary. If Both is selected, you can access both the hard-disk drive and the CD-ROM drive. If Primary is selected, only the hard-disk drive is accessible.

FDD Controller

Enables the diskette-drive controller. If this option is set to Disabled, the diskette drive is unavailable.

CD-ROM Drive Speed

CD-ROM Drive Speed allows you to choose between High Performance (the default) and Variable. When this option is set to High Performance, the CD-ROM drive runs at the maximum possible speed. When set to Vari- able, the CD-ROM drive slows down to avoid vibration caused by unbalanced CDs.

Plug & Play O/S

The Setup program automatically detects whether the computer is running a Plug and Play operating system such as Windows 95.

Serial Port

Serial Port lets you map the address of the serial port to avoid address conflicts with other devices or disable the port for security. The default setting is PnP OS, and the default Base I/O and IRQ address is 3F8 IRQ4. It is rec- ommended that you retain the default setting.

If you are using Windows 95 and this option is set to PnP OS, the operating system can remap the port automati- cally to avoid address conflicts with other devices. If any

other setting is used, this automatic mapping does not occur.

If for some reason you need to change the serial port address, be careful not to create a conflict with the address of the infrared port.

NOTE: If there is a conflict between two or more addresses, an asterisk appears next to the port type in the System Devices menu.

Infrared Port

Infrared Port lets you map the address of the infrared port to avoid address conflicts with other devices. The default setting is Disabled. It is recommended that you retain the default settings.

If you are using Windows 95 and this option is set to PnP OS, the operating system can remap the port automati- cally to avoid address conflicts with other devices. If any other setting is used, this automatic mapping does not occur.

If you want to use the high-speed infrared feature, see the readme.doc file on the Fast Infrared Drivers diskette that you made with the Dell Program Diskette Maker. In the Microsoft Windows 95 operating system, access the Dell Program Diskette Maker through the Dell Accesso- ries folder.

If for some reason you need to change the infrared port address in the Setup program, be careful not to create a conflict with the addresses of the serial port or the paral- lel port.

NOTE: If there is a conflict between two or more addresses, an asterisk appears next to the port type in the System Devices menu.

Parallel Port

Parallel Port controls whether the computer’s parallel port acts as an AT-compatible (unidirectional), PS/2-compatible (bidirectional), EPP-compatible, or ECP-compatible port. Options are PnP OS (the default), Disabled, Enabled, and Auto. The default mode is ECP. Other possible mode settings are Normal, EPP, and Bi- directional.

When set to PnP OS, the operating system automatically configures the parallel port. When set to Auto, the com- puter’s BIOS configures the parallel port.
