Primary identifies drives attached to the primary enhanced integrated drive electron-
ics (EIDE) interface connector (labeled "IDE1") on the system board; Secondary
identifies drives connected to the secondary EIDE interface connector (labeled
"IDE2").
For both the Primary and the Secondary drive sections, the Drive 0 and Drive 1
options identify the type of EIDE hard-disk drives installed in the computer. For each
drive, seven parameters can be chosen as a group by drive-type number, entered indi-
vidually from the keyboard or set automatically. A drive-type number specifies the
parameters of a hard-disk drive based on a table recorded in the system's BIOS.
To choose a setting, type characters from the keyboard or use the left- or right-arrow
key to cycle through the choices.
The settings are:
Auto
None
Usr1 or Usr2
A specific drive-type number
NOTES: The Primary and Secondary drive sections identify only EIDE drives. If a drive
other than an EIDE drive (that is, a SCSI drive) is installed, the corresponding setting in
the Primary and Secondary drive sections should be None.
Operating systems that bypass the system BIOS may not obtain optimum hard-disk
drive performance.

For EIDE CD-ROM and EIDE tape drives that use the built-in EIDE controller, it is rec-
ommended that you use the secondary EIDE interface connector if a hard-disk drive is
attached to the primary EIDE interface connector.
For all EIDE devices, set the appropriate Drive option to Auto.

For EIDE hard-disk drives, the system provides an automatic drive-type detect feature.
To use this feature for Drive 0, highlight the Drive 0 option and type a (for automatic ).
To use it for Drive 1, type a at the Drive 1 option. In each case, the setting changes to
Auto. After you reboot the system, the System Setup program automatically sets the
correct drive parameters for each drive.
Before installing a new EIDE hard-disk drive, also check the documentation that came
with the drive to verify that all jumper settings on the drive are appropriate for your
configuration.
NOTE: If you are using a hard-disk drive that was shipped by Dell, use the Auto
setting.
