rror Messages
When you run a test group or subtest in the diagnostics,
error messages may result. These particular error mes-
sages are not covered in this guide because the errors that
generate these messages can be resolved only with a
technician’s assistance. Record the messages on a copy of
the Diagnostics Checklist found in Chapter 5, and read
that chapter for instructions on obtaining technical
assistance.
R
AM Test Group
The RAM Test Group subtests check all the directly
addressable RAM. You should run the stand-alone RAM
Test program (ramtest.exe) from the MS-DOS prompt if, for
some reason, the diagnostics cannot load into memory.
The RAM Test program has switches so that you can set
both test limits and options for the subtests from the
MS-DOS prompt. The switches listed in Table 4-3 can be
added to the end of the ramtest command line.
The switches can be used in any order, but they must be
separated by a space.
For example, to run the RAM comprehensive subtest
10 times without pausing, stopping at a maximum of
20 errors, and outputting the results to a file named
ramtst.rpt, type the following command line at the MS-DOS
prompt and press <
ENTER
>:
ramtest -r10 -np -m20 -oframtst.rpt
To view the Help screen that lists all of the ramtest
command-line switches, type the following command at the
MS-DOS prompt and press <
ENTER
>:
