Running the Dell Diagnostics: Dell Latitude CP
Error Messages
When you run a test group or subtest in the diagnostics, error messages may result. These
particular error messages 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
Getting Help and read that section for instructions
on obtaining technical assistance.
RAM 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 that allow you to 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>:
ramtest?
Table 4-3. RAM Test Switches
Switch Description

The default value is 1.
