Running the Dell Diagnostics 4-9
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, return to the main
screen of the diagnostics by pressing the <Esc> key. The
values you selected under Test Limits remain in effect
until you change them or exit the diagnostics. The values
are reset to their defaults when you restart the
diagnostics.
Press <Page Down> to select the next menu for the test
limits in a category.
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 to exit the diagnostics
and return to an MS-DOS prompt. Remove your diagnos-
tics diskette from drive A, and reboot the computer by
pressing <Ctrl><Alt><Del>.

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 operation 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.
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.
