S
ystem Setup Categories
The following subsections explain in detail each of the
categories on the System Setup screens.
Time
Time resets the time on the computer’s internal clock.
Time is kept in a 24-hour format (hours:minutes:sec-
onds). To change the time, press the right-arrow key to
increase the number in the highlighted field or press the
left-arrow key to decrease the number. If you prefer, you
can type numbers in each of the appropriate fields.
Date
Date resets the date on the computer’s internal calendar.
Your system automatically displays the day of the week
corresponding to the settings in the three fields that
follow (month, day-of-month, and year).
To change the date, press the right-arrow key to increase
the number in the highlighted field or press the left-arrow
key to decrease the number. If you prefer, you can type
numbers in the month and day-of-month fields.
Diskette Drive A and Diskette Drive B
Diskette Drive A and Diskette Drive B identify the type
of diskette drives installed in your computer. With the
standard cabling configuration, Diskette Drive A (the
boot diskette drive) is the 3.5-inch diskette drive installed
in the top externally accessible drive bay; Diskette
Drive B is any drive installed in the bottom externally
accessible drive bay that is connected to the system’s
diskette/tape drive interface.
The category options always match the physical locations
of the drives in your computer—the first drive listed on
Page 1 of the System Setup screens is the top drive in
your computer.
The options are:
•
5.25 Inch, 360 KB
•
5.25 Inch, 1.2 MB
•
3.5 Inch, 720 KB
•
3.5 Inch, 1.44 MB
•
Not Installed
NOTE: Tape drives are not reflected in the Diskette
Drive A and Diskette Drive B categories. For example, if
you have a single diskette drive and a tape drive attached
to the diskette/tape drive interface cable, set the Diskette
Drive A category to match the characteristics of the
diskette drive and set the Diskette Drive B category to
Not Installed.
Drives: Primary and Secondary
Primary identifies drives attached to the primary
enhanced integrated drive electronics (EIDE) interface
connector (labeled “IDE1”) on the system board;
Secondary identifies drives connected to the secondary
EIDE interface connector (labeled “IDE2”). It is recom-
mended that you use the secondary EIDE interface
connector for EIDE CD-ROM and EIDE tape drives.
NOTE: For all devices from Dell that use the built-in
EIDE controller, set the appropriate
Drive category to
Auto.
For both the Primary and Secondary drive sections, the
Drive 0 and Drive 1 categories identify the type of EIDE
devices installed in the computer. For each drive, seven
parameters can be chosen as a group by drive-type
number, entered individually from the keyboard or set
automatically. A drive-type number specifies the parame-
ters of a hard-disk drive based on a table recorded in the
system’s BIOS.
To choose a setting for these categories, type characters
from the keyboard or use the left- or right-arrow key to
cycle through the choices. The options are:
•
Auto (use this setting for all EIDE devices from
Dell)
•
None
•
USR1 or USR2
•
A specific drive-type number
NOTE: Operating systems that bypass the system BIOS
may not obtain optimum hard-disk drive performance.
