Using System Setup 51
COM2 Mode: Sets the mode for the COM 2 port. You can
use the COM2 port for the internal infrared device.
Options are FIR (fast infrared) (default) and Disabled. If
you choose the option FIR, you can set an additional
field, FIR Channel, to DMA 0, DMA 1, or DMA 3 (default).
LPT port: Sets the base address and IRQ line for the
parallel port. The options for this field are Disabled; Auto;
378, IRQ 7 (default); 278, IRQ 7; 298, IRQ 7; 378, IRQ 5;
278, IRQ 5; and 298, IRQ 5.
If you do not have a peripheral device attached to your
parallel port, specify Disabled. This saves power and
serves as an additional security measure because a
parallel device attached to your computer will not
function.
LPT Mode: Sets the mode of the parallel port. The
options are Bi-directional, Output only, EPP, or ECP
(default). If you change this option, you must reboot
your computer before the change can take effect.
Diskette controller: Enables the on-board floppy disk
controller. The options are Enabled (default) and Disabled.
Local Bus IDE adapter: Enables the integrated IDE local
bus adapters. Options are Both (default), Disabled,
Primary, and Secondary. The Both option enables both the
primary IDE adapter (for the hard drive) and the
secondary IDE adapter (for the CD-ROM drive) on the
computer.
PS/2 Mouse: Enables (default) or disables the PS/2 mouse and
keyboard port and disables the touchpad. If you set this field to
Disabled, a device attached to the port will not function, but you
will free up an IRQ for use by another device.
Screen Expansion: Enables the expansion of the screen during
boot. When your computer starts, the screens are in 640x480
resolution during boot and then automatically change to the
resolution you have specified in the Windows settings. When
this field is enabled, the opening screens are expanded beyond
640x480. The default is Disabled.
USB Device: Enables (default) or disables the USB port.
