Using the System Setup Program: Dell OptiPlex GX1 Low-Profile Managed PC Systems

connector for EIDE CD-ROM and EIDE tape drives.

NOTES: For all devices from Dell that use the built-in EIDE controller, set the appropriate Drive option to Auto. For small computer system interface (SCSI) devices, set the appropriate Drive option to None.

You must have an EIDE device connected to the primary EIDE interface if you have an EIDE device connected to the secondary EIDE interface.

For older EIDE hard-disk drives not shipped with the system from Dell and less than 528 megabytes (MB) in capacity, you can use one of the following options if the Autodetect feature does not work:

A specific drive-type number

Usr1 or Usr2

For each drive, seven parameters can be chosen as a group by drive-type number or entered individually from the keyboard. A drive-type number specifies the parameters of a hard-disk drive, based on a table recorded in the system's BIOS.

NOTE: Operating systems that bypass the system BIOS may not obtain optimum hard-disk drive performance.

If you choose the Usr1 or Usr2 option, you must supply the following parameters for the drive:

Type is the drive-type number for the selected hard-disk drive (in this case, Usr1 or Usr2). Cyls is the number of logical cylinders.

Hds indicates the number of logical heads in the drive.

Pre (precompensation cylinder) is the cylinder number at which the electrical current for the drive head changes to compensate for differences in data density across the disk surface (this parameter has no effect for EIDE drives).

Lz is the cylinder number that is used as the drive's landing zone for the heads when the drive is not in use.

Sec is the number of logical sectors per track.

Size (automatically calculated by the system) indicates the number of millions of bytes of storage provided by the drive.

Reserved Memory

Reserved Memory allows you to designate a region of system board memory that can be supplied by an expansion card. You should not enable the reserved memory feature unless you are using an expansion card that requires special addressing.

For example, you may have a memory expansion card that needs to be addressed starting at 15 MB. Selecting the 15M - 16M option in the Reserved Memory option specifies that the base memory from 15 to

16 MB comes from the memory expansion card (the base memory below the 15-MB address comes from the dual in-line memory modules [DIMMs] on the system board).

The Reserved Memory option has the following options:

None (the default option) 512K - 640K
