is selected, you can access both the hard-disk drive and the media bay device(s). If Primary is selected,

only the hard-disk drive and megabit device is accessible. When Disabled, the media bay device(s) and

hard-disk drive are disabled.

FAD Controller

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

option defaults to Disabled when an LS-120 drive is installed.

Internal Touchpad

When set to Enabled (default), allows the touch pad to continue working when an external mouse or other

pointing device is connected. Auto Disabled disables the touch pad when an external pointing device is

connected.

Serial Port

Lets you map the address of the serial port to avoid address conflicts with other devices or disable the port

for security. When set to Auto, allows the operating system or the BIOS to configure the port automatically.

When set to Customized (default), sets the Base I/O address/IRQ to 3F8 IRQ4. If there is a conflict

between two or more addresses, an asterisk appears next to the port type. Off disables the serial port to

conserve power.

Infrared Port

Lets you map the address of the infrared port to avoid address conflicts with other devices. The default is

Off. Dell recommends that you retain the default unless you are using an infrared device with the computer.

When this option is set to Customized, the Mode is SIR and the Base I/O address/IRQ is 2F8 IRQ3. If

you change the infrared port address, be careful not to create a conflict with the addresses of the serial port

or the parallel port. If there is a conflict between two or more addresses, an asterisk appears next to the port

type.

Parallel Port

Controls whether the computer’s parallel port acts as an AT-compatible (unidirectional), PS/2-compatible

(bidirectional), EPP-compatible, or ECP-compatible. When this option is set to Customized (default), the

Mode is ECP, the Base I/O address is 378, the Interrupt is IRQ 7, and the DMA channel is DMA3. The

Auto setting allows the operating system or the BIOS to configure the port automatically. When the option is

set to Off, the port is disabled and you can use its assigned LPT resources for another device. If you

change the parallel port address and/or DMA channel, be careful not to create a conflict with the address or

DMA channel of the infrared port.

Modem

Appears in the Setup program only if the computer has an internal modem. This option has no user-

selectable settings.
