Serial Port 1 and Serial Port 2 — Settings are Off and Auto (default). (Serial Port 2 appears as an option if you have a serial port
card installed.)
Auto automatically configures a connector to a particular designation ( COM1 or COM3 for Serial Port 1 ; COM2 or COM4 for Serial
Port 2 ).
If you set a serial connector to Auto and add a card containing a connector configured to the same designation, the computer
automatically remaps the integrated port to the next available connector designation that shares the same IRQ setting as follows:
COM1 (I/O address 3F8h), which shares IRQ4 with COM3 , is remapped to COM3 (I/O address 3E8h).
COM2 (I/O address 2F8h), which shares IRQ3 with COM4 , is remapped to COM4 (I/O address 2E8h).
NOTE: When two COM connectors share an IRQ setting, you can use either connector as necessary, but you may not be able to use them
both at the same time. If you are running the Windows 95 or IBM ® OS/2 ® operating system, you cannot use both serial connectors at the
same time. If the second connector (COM3 or COM4) is also in use, the integrated connector is turned off.
l
Parallel Port — Settings are Mode , I/O Address , and DMA Channel .
Mode settings are PS/2 , EPP , ECP , AT , or Off . Set the Mode option according to the type of device connected to the parallel
connector. To determine the correct mode to use, see the documentation that came with the device.
I/O Address settings are 378h (default), 278h , or 3BCh . The settings are not available when Mode is set to Off .
NOTE: You cannot set the parallel connector to 3BCh if Mode is set to EPP .
DMA Channel appears only when Mode is set to ECP. Settings are DMA 1 , DMA 3 , or Off .
l
IDE Drive Interface — Settings are Off and Auto (default).
Auto turns off the IDE interface when necessary to accommodate a controller card installed in an expansion slot.
l
Diskette Interface — Settings are Auto (default), Read Only , and Off .

Read Only prevents the computer's integrated floppy drive controller from writing to floppy drives and activates Auto .
