Parallel Port; Parallel Mode; Hard Disk; Diskette - Dell OptiPlex GXi Reference And Installation Manual

NOTE: When two COM ports share an IRQ setting, you
can use either port as necessary, but you may not be able
to use them both at the same time.
For more information about built-in ports, port designa-
tions, IRQs, and the remapping of ports, see "Connecting
External Devices" in your online System User's Guide.

Parallel Port

configures the system's built-in parallel
PARALLEL PORT
port. This category can be set to
alternate addresses
278H
port.
NOTE: Do not set
PARALLEL PORT
an Extended Capabilities Port (ECP) device connected to
the port.

Parallel Mode

controls whether the system's built-in
PARALLEL MODE
parallel port acts as an AT-compatible (unidirectional) or
PS/2-compatible (bidirectional) port.
Your system also supports ECP mode, which can be used
by the Windows 95 operating system. Windows 95 uses
ECP protocol automatically if it detects an ECP-capable
device.
Set this category according to the type of peripheral
device connected to the parallel port. To determine the
correct mode to use, see the documentation that came
with the device.

Hard Disk

enables or disables the system's built-in EIDE
HARD DISK
hard-disk drive interface.
With (the default option) selected, the system turns
AUTO
off the built-in EIDE interface when necessary to accom-
modate a controller card installed in an expansion slot.
As part of the boot routine, the system first checks for a
primary hard-disk drive controller card installed in an
expansion slot. If no card is found, the built-in EIDE
interface is enabled, using IRQ14 and IRQ15.
If a primary controller is detected on the expansion bus,
the built-in EIDE interface is disabled.
Selecting disables the built-in EIDE interface.
OFF
(the default), to

, or to

Diskette

controls the operation of the system's built-in
DISKETTE
diskette/tape drive controller.
With (the default option) selected, the system turns off
AUTO
the built-in diskette/tape drive controller when necessary to
accommodate a controller card installed in an expansion slot.
With selected, nothing can be written to dis-
WRITE-PROTECT
kette drives and tape drives using the system's built-in diskette/
tape drive controller. (The system can still read from the
drives.) When this option is selected, the

code (ECC) capability is turned
Your system supports ECC only if all the installed
DIMMs are ECC DIMMs. If any of the installed DIMMs
are not ECC DIMMs, this category does not appear.
