CAUTION. Before running the QAPlus/WIN tests, be aware of the following
software bugs.
H
The QAPlus/WIN discrete memory test fails if the computer being tested
contains more than 16 Megabytes of RAM.
If your computer contains more than 16 Megabytes of RAM, do not run the
discrete memory test from the Memory icon. Use the Run Quick Test or Run
Full Test item from the Tests menu, or use the Quick Test icon in the
QAPlus/WIN title box.
H
The QAPlus/WIN hard drive test reports an incorrect number of tracks and
cylinders for your hard drive.
This is an internal mapping problem, but has no effect on the results of the
test. Bad sectors on your hard drive are still found and marked.
H
The installation program for QAPlus/WIN stalls at the end of the installation
process.
To continue after the installation process stalls, press CTRL–ALT–DEL,
highlight the QAPlus/WIN installation program in the resulting menu, then
click on End Task.
H
The QAPlus/WIN keyboard test does not respond correctly to the Windows
95-specific keys found on Windows 95 enhanced keyboards.
Keyboards made for use with Windows 95 contain two or three keys specific
to that operating system. These are usually located on either side of the space
bar. QAPlus/WIN does not “trap” these keys when performing the keyboard
test. Do not press them.
To run the QAPlus/WIN diagnostics, do the following steps:
1. Turn off all other applications.
2. Click on START in the tool bar.
3. Select Programs from the Start menu.
4. Select Qaplusw.exe.
(Refer to the help section in QAPlus/WIN for more information on running
QAPlus/WIN).
TLA 700 mainframe diagnostics.
If the benchtop controller passes all the QAPlus/
WIN tests, the primary tree calls for you to run the TLA 700 Mainframe
Diagnostics. The TLA 700 Mainframe Diagnostics are a comprehensive software
test that checks benchtop chassis as well as benchtop controller functionality. If
the TLA 700 Mainframe Diagnostics test fails to run correctly, the benchtop
controller is defective.
