Dell 7500 manual Base I/O address is 378, the Interrupt is IRQ 7

Table B-2. System Devices Menu Options (continued)

Option	Function
Parallel Port	Controls whether the computer’s parallel port acts as an
	AT-compatible (unidirectional), PS)/2-compatible (bidirec-
	tional), 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 operat-
	ing 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
	interal modem. This option has no user-selectable settings.
