Dell PowerEdge 6400 - Manual (Page 75)

Parallel Port configures the system's integrated parallel port. Parallel Port can be set to 378h (the default), to alternate addresses 278h or
3BCh, or to Off to disable the port.
Parallel Mode
Parallel Mode controls whether the system's integrated 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
Diskette controls the operation of the system's integrated diskette drive controller.
With Auto (the default) selected, the system turns off the integrated diskette drive controller 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 integrated 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 integrated diskette drive controller as
necessary) is also in effect.
Selecting Off turns off the integrated diskette controller; this option is used primarily for troubleshooting purposes.
USB
USB enables or disables the system's Universal Serial Bus (USB) ports. Disabling the USB ports makes system resources available for other
devices.
Primary SCSI and Secondary SCSI
Primary SCSI and Secondary SCSI turn the respective SCSI controller on or off. Selecting On (the default option) enables the integrated PCI
SCSI controller and scans the associated ROM. For the system to boot from a drive attached to the integrated SCSI controller, the drive must be
enabled. Selecting Off causes the BIOS to mask the presence of a device.
NIC
NIC determines whether the system's integrated network interface controller (NIC) is Enabled or Disabled (the default). Changes take effect after
reboot.
NIC MAC Address
The MAC Address field displays the address of the media access control (MAC) address used by the integrated NIC. This field has no user-
selectable settings.
System Data
The following fields, which are not selectable, display information about the system:
l The processor line displays the microprocessor type and speed.
l Level 2 Cache displays the size of the integrated cache (512 kilobytes [KB]).
l System Memory indicates the entire amount of installed memory detected in your system, except for memory on Expanded Memory
Specification (EMS) expansion cards. After adding memory, check System Memory to confirm that the new memory is installed correctly
and is recognized by the system.
l Video Memory displays the amount of video memory detected in your system.
l
Service Tag displays the system's five-character service tag number, which was programmed into NVRAM by Dell during the manufacturing
process. Refer to this number during technical assistance or service calls. The service tag number is also accessed by certain Dell support
software, including the diagnostics software.
l Asset Tag displays the customer-programmable asset tag number for the system if an asset tag number has been assigned. You can use
the
Asset Tag utility , which is included with your software support utilities, to enter an asset tag number up to ten characters long into
NVRAM.
Using the System Password Feature
NOTICE: The password features provide a basic level of security for the data on your system. However, they are not foolproof. If
NOTE: Do not set Parallel Port to 278h if you have an Extended Capabilities Port (ECP) device connected to the port.
