Parallel Port; Parallel Mode; Diskette; Primary Scsi A, Primary Scsi B And Secondary Scsi - Dell PowerEdge 6350 User Manual

NOTE: When two COM ports share an IRQ setting, you can use either port as neces-
sary, 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 built-in port is turned off.
Parallel Port configures the system's built-in parallel port. Parallel Port can be set to
378h (the default), to alternate addresses 278h or 3BCh, or to Off to disable the port.
NOTE: Do not set Parallel Port to 278h if you have an Extended Capabilities Port
(ECP) device connected to the port.
Parallel Mode controls whether the system's built-in parallel port acts as an
AT-compatible (unidirectional) or PS/2-compatible (bidirectional) port.
Set Parallel Mode 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.
Diskette controls the operation of the system's built-in diskette drive controller.
With Auto (the default) selected, the system turns off the built-in diskette drive con-
troller when necessary to accommodate a controller card installed in an expansion
slot.
With Write Protect selected, nothing can be written to diskette drives using the
system's built-in diskette drive controller. (The system can still read from the drives.)
When this option is selected, the Auto option (whereby the system turns off the
built-in diskette drive controller as necessary) is also in effect.
Selecting Off turns off the built-in diskette controller; this option is used primarily for
troubleshooting purposes.
Primary SCSI A, Primary SCSI B, and Secondary SCSI turn the respective SCSI
controller on or off. Selecting On (the default option) enables the built-in PCI SCSI con-
troller and scans the associated read-only memory (ROM). For the system to boot
from a drive attached to the built-in SCSI controller, the drive must be enabled. Select-
ing Off causes the BIOS to mask the presence of a device.
The following fields, which are not selectable, display information about the system:
The processor line displays the microprocessor type and speed.
Level 2 Cache displays the size of the integrated cache (512 kilobytes [KB]).
