Integrated Devices
Integrated Devices
configures the following devices integrated with the system board:
l
Sound
l
Network Interface Controller
l
Mouse Port
l
Serial Port 1
and
Serial Port 2
l
Parallel Port
l
IDE Drive Interface
l
Diskette Interface
l
USB Emulation
l
PC Speaker
l
Video DAC Snoop
l
SCSI Controllers
Press <Enter> to configure these options as explained in the following subsections.
Sound
Sound
determines whether the integrated audio controller is
On
or
Off
. The default is
On
.
Network Interface Controller
Network Interface Controller
determines whether the integrated NIC is
On
,
Off
, or
On
w/ MBA
. The default is
On. On w/ MBA
means that the
NIC is enabled and set to boot the system remotely from a network server. If you select
On w/ MBA
, you are prompted to press <Ctrl><Alt><b> at
the Dell logo screen during the boot routine. A menu then appears that allows you to select
PXE
,
RPL
,
BootP
, or
NetWare
as the active boot
mode.
Mouse Port
Mouse Port
enables or disables the system's integrated Personal System/2 (PS/2)-compatible mouse port. Disabling the mouse allows an
expansion card to use interrupt request (IRQ)12.
Serial Port 1 and Serial Port 2
Serial Port 1
and
Serial Port 2
configure the system's integrated serial ports. You can set these options to
Auto
(the default) to automatically
configure a port, to a particular designation (
COM1
or
COM3
for
Serial Port 1
;
COM2
or
COM4
for
Serial Port 2
), or to
Off
to disable the port.
If you set a serial port to
Auto
and add an expansion card containing a port configured to the same designation, the system automatically remaps
the integrated port to the next available port designation that shares the same IRQ setting as follows:
l
COM1
(input/output [I/O] address 3F8h), which shares IRQ4 with
COM3
, is remapped to
COM3
(I/O address 3E8h).
l
COM2
(I/O address 2F8h), which shares IRQ3 with
COM4
, is remapped to
COM4
(I/O address 2E8h).
Parallel Port
Parallel Port
configures the system's integrated parallel port. Press <Enter> to configure
Parallel Port
options as explained in the following
subsections.
For LS-120 SuperDisk drives installed in place of a 1.44-MB diskette drive, set these options to
Not Installed
.
If your system has a 1.44-MB diskette drive as Diskette Drive A and you install an LS-120 SuperDisk drive in one of the lower externally
accessible drive bays, the system automatically assigns drive letter
B
to it.
NOTE: The link integrity and activiy indicators on the NIC remain active as long as the system is plugged into an electrical outlet. This
remains true even if the system is turned off or if the
Network Interface Controller
or
Remote Wake Up
options are disabled in
System Setup.
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. If the second port (
COM3
or
COM4
) is also in use, the integrated port is turned off.
