or a subtest (from the Subtest menu), you set the limits
for all the subtests in that test group. When you select
Test Limits, 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
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/Infrared Ports
Test Group, you 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 for
all the test groups or subtests you run, unless you change
them. However, the values are reset to their defaults
when you restart the diagnostics.

Quit

Selecting Quit from the Main Menu exits the diagnostics
and returns you to your operating system environment.
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 System Diagnostics
To troubleshoot components or devices, run the appropri-
ate test (test group or subtest) in the diagnostics. The
diagnostics exercises the functional components and
devices of the computer system more vigorously and
thoroughly than they are exercised during normal opera-
tion. The diagnostics is organized by components into
test groups and subtests within each test group. Each sub-
test is designed to detect any errors that may interfere
with the normal operation of a specific device of the
computer.
NOTE: Some subtests requiring hardware not listed in
the System Configuration area of the diagnostics screen
appear to run, but they conclude with a status message
stating Component not present (or disabled).
Table 5-2 lists the diagnostic test groups, their subtests,
and comments concerning their use.
