The RAM test group, the Video test group, the Serial/
Infrared Ports test group, the Diskette Drives test group,
the Parallel Ports test group, the SCSI Devices test group,
and the Hard-Disk Drives (Non-SCSI) test group allow
you to designate limits. Whether you select Test Limits
for a entire test group (from the Main menu) or a single
subtest (from the Subtest menu), you set the limits for all
the subtests in that test group. When you select Test Lim-
its, a new screen appears and the Key Help area lists keys to
use with the new screen.
How you change a value for the limits of a test group or
subtest depends on the type of parameter associated with
it. Different keys are used to change values for different
types of parameters. For example, memory address limits
specified for the RAM test group are changed by typing
in numbers over the digits of a given limit or by pressing
the plus (+) or minus (–) key to increase or decrease the
given limit. In contrast, to set limits for the Serial Ports
test group, use the <Spacebar> to toggle between Yes and
No.
After you are satisfied with the limits, press <Page
Down> to select the next menu or submenu in the Test
Limits category. Press <Esc> to return to the main Test
Limits menu. The values you selected under Test Limits
remain in effect until you change them or exit the diagnos-
tics. The values are reset to their defaults when you restart the
diagnostics.

About

About in the Main menu displays information about the
highlighted test group, such as limits and parameters and
how to set them.

Key-Help

Key-Help displays a list of key controls available for the
selected option.

Quit

Select Quit from the Main menu (or press <q>) to exit the
diagnostics and return to an MS-DOS prompt.
After you return to the operating system environment,
remove your diagnostics diskette from drive A and reboot the
computer.
CAUTION: It is important that you quit the diag-
nostics program correctly, because the program
writes data to the computer's memory that can
cause problems unless properly cleared.
T
ests in the Dell Diagnostics
The diagnostics is organized by components into test groups
and subtests within each test group. Each subtest is designed
to detect any errors that may interfere with the normal opera-
tion of a specific device of the computer.
NOTE: Any subtest requiring hardware not listed in the
System Configuration area appears to run, but the sub-
test concludes with a status message stating Component
not available.
Table 4-2 lists the diagnostic test groups, their subtests,
and comments concerning their use.
