Using the System Setup Program 3-7'ULYHV3ULPDU\DQG6HFRQGDU\Primary identifies drives attached to the primary enhanced integrated drive electron-ics (EIDE) interface connector (labeled “IDE1”) on the system board; Secondaryidentifies drives connected to the secondary EIDE interface connector (labeled“IDE2”).For both the Primary and the Secondary drive sections, the Drive 0 and Drive 1options identify the type of EIDE hard-disk drives installed in the computer. For eachdrive, seven parameters can be chosen as a group by drive-type number, entered indi-vidually from the keyboard or set automatically. Adrive-type number specifies theparameters 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-arrowkey to cycle through the choices.The settings are:á Autoá Noneá Usr1 or Usr2á A specific drive-type numberNOTES: The Primary and Secondary drive sections identify only EIDE drives. If a driveother than an EIDE drive (that is, a SCSI drive) is installed, the corresponding setting inthe Primary and Secondary drive sections should be None.Operating systems that bypass the system BIOS may not obtain optimum hard-diskdrive performance.(,'( 'HYLFHV 2WKHU 7KDQ +DUG'LVN 'ULYHVFor 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 isattached to the primary EIDE interface connector.For all EIDE devices, set the appropriate Drive option to Auto.(,'( +DUG'LVN 'ULYHVFor 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 (forautomatic).To use it for Drive 1, type a at the Drive 1 option. In each case, the setting changes toAuto. After you reboot the system, the System Setup program automatically sets thecorrect drive parameters for each drive.Before installing a new EIDE hard-disk drive, also check the documentation that camewith the drive to verify that all jumper settings on the drive are appropriate for yourconfiguration.NOTE: If you are using a hard-disk drive that was shipped by Dell, use the Autosetting.23205BK0.BK : 23205C30.FM Page 7 Wednesday, March 18, 1998 1:51 PM
