With Auto (the default option) selected, the system turns off the built-in 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 and tape 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/tape drive controller; this option is used pri- marily for troubleshooting purposes.

Speaker determines whether the on-board speaker is On (the default) or Off. A change to this option takes effect immediately (rebooting the system is not required).

The following options, which are not selectable, display information about the system. The microprocessor type is also listed in the System Data box.

‡Level 2 Cache displays the size of the integrated cache (512 kilobytes [KB]).

‡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 this option to confirm that the new memory is installed correctly and is recognized by the system.

‡Video Memory displays the amount of video memory detected in your system.

‡Service Tag displays the system’s five-character service tag number, which was programmed into nonvolatile random-access memory (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.

‡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 num- ber up to ten characters long into NVRAM. For information on using the utility, see “Using Drivers and Utilities” in your online System User’s Guide.
