Identifies type of diskette drives installed. Category options always match physical locations of drives in computer. Tape drives are not reflected in these categories. NOTE: For OptiPlex NX1 chassis, a single diskette drive can be used for service purposes only. Identifies drives attached to the IDE1 and IDE2 connectors on system board. Each EIDE connector supports two EIDE drives (Drive 0 and Drive 1). For EIDE hard-disk drives, the system provides an automatic drive-type detect feature. To use this feature, highlight the appropriate Drive category and type a (for automatic). If none of the supported drive types matches the parameters of the new drive, enter parameters directly. To do so, highlight the appropriate Drive category (Drive 0 or Drive 1) and type u to display . Press to highlight each of the parameter fields in suc- cession, and enter the appropriate number for each field. NOTES: For EIDE devices such as EIDE CD-ROM drives and EIDE tape drives that are using the built-in EIDE controller, set the appropriate Drive category to Auto. OptiPlex NX1 chassis supports only one harddisk drive and no CD-ROM drive or tape drive. Designates a region of system board memory that can be supplied by an expansion card. This feature should not be enabled unless an expansion card that requires special addressing is installed. Indicates processor speed at which system boots-the processor's rated speed or a slower compatibility speed, which disables cache. Determines whether keyboard's Num Lock mode is activated. A-4

NOTES: For EIDE devices such as EIDE
CD-ROM drives and EIDE tape drives that are
using the built-in EIDE controller, set the
appropriate Drive category to Auto.
OptiPlex NX1 chassis supports only one hard-
disk drive and no CD-ROM drive or tape drive.
Reserved Memory
Designates a region of system board memory
that can be supplied by an expansion card.
This feature should not be enabled unless an
expansion card that requires special address-
ing is installed.
CPU Speed
Indicates processor speed at which system
