Dell OptiPlex GX260 - Manual (Page 25)

Diskette Drive A (the boot floppy drive) is the 3.5-inch floppy drive installed in the top externally accessible
drive bay. The two options are 3.5 Inch, 1.44 MB, and Not Installed.
Tape drives are not reflected in the Diskette Drive A option. For example, if a single floppy drive and a tape
drive are attached to the floppy drive interface cable, set Diskette Drive A to 3.5 Inch, 1.44 MB.

USB Device
NOTE: To boot from a USB memory device, select the USB device and move it to make it the first device.
Integrated Devices— Configures the following devices integrated with the system board:
Sound — Settings are On (default) or Off.
USB Controller — Settings are On or Off.
Network Interface Controller — Settings are On (default), Off, or On w/ PXE. Settings for On w/
PXE are PXE, RPL, BootP, or NetWare as the active boot mode.
Mouse Port — Settings are On or Off.
Serial Port 1 and Serial Port 2 — Settings are Off and Auto (default).
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.
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.
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.
Diskette Interface — Settings are Auto (default), Read Only, and Off
Auto turns off the integrated floppy drive controller when necessary to accommodate a controller card
installed in an expansion slot.
Read Only prevents the computer's integrated floppy drive controller from writing to floppy drives and
activates Auto.
USB Emulation — Settings are On and Off (default for Windows NT®)
Primary Video Controller — When video is integrated on the system board, the options are Auto
(default) and Onboard.
