DMA Channel
: This option determines the direct memory access
(DMA) channel used by the parallel connector and appears only
when
Mode
is set to
ECP
. The available options are
DMA 1
,
DMA 3
, and
Off
.
–
IDE Drive Interface
: enables or disables the computer's
integrated device electronics (IDE) hard drive interface. With
Auto
(the default) selected, the computer turns off the IDE
interface when necessary to accommodate a controller card
installed in an expansion slot. As part of the boot routine, the
computer first checks for a primary hard drive controller card
installed in an expansion slot. If no card is found, the computer
enables the IDE interface to use IRQ14 and IRQ15. If a primary
controller is detected on the expansion bus, the IDE interface is
disabled. Selecting
Off
disables the IDE interface.
–
Diskette Interface
: controls the operation of the computer's
integrated floppy drive controller. With
Auto
(the default)
selected, the computer turns off the integrated floppy drive
controller when necessary to accommodate a controller card
installed in an expansion slot.
With
Read Only
selected, nothing can be written to any floppy
drive using the computer's integrated floppy drive controller. (The
computer can still read from the drives.) When
Read Only
is
selected,
Auto
is also in effect, meaning that the computer turns
off the integrated floppy drive controller as necessary.
Selecting
Off
turns off the integrated floppy drive controller; this
setting is used to control the use of this legacy device or for
troubleshooting purposes.
–
USB Emulation
: determines whether the computer's basic
input/output system (BIOS) controls Universal Serial Bus (USB)
keyboards and mice. When
On
is selected (the default), the BIOS
controls USB keyboards and mice until a USB driver is loaded by
the operating system. When
Off
is selected, the BIOS does not
control USB keyboards and mice, although they function during
the boot routine. Set USB Emulation to
Off
if you are using a
PS/2-compatible keyboard and mouse.
NOTE:
For Windows NT
®
,
Off
is the default setting.
