Dear Customer,

To help us to troubleshoot the problem, we have 
enclosed two diagnostic test programs. Please run
TESTVB.EXE first then CHECKVB.COM.

1. TESTVB.EXE   

At DOS prompt, enter TESTVB. The test can continue to
run even when there is an error, so just hit ENTER when 
you encounter any error message prompt.

This test will first scan the hardware and a menu will
pop up which list down different test module. Use up and 
down arrow key to pick the module and hit ENTER to start 
the test.

Please list down any error messages or codes returned.

2. CHECKVB.COM

At DOS prompt, enter CHECKVB [<PortAddr>]. This PortAddr
will be the port address set in the autoexec.bat.


For example, in the autoexec.bat you will see
        VIDEOBLST=C:\VBLASTER A2AD6 I10
This means your video blaster port address is 2AD6.
Your command line will then be

        CHECKVB 2AD6

We also need the following information from you.

1. Your autoexec.bat, config.sys and system.ini.

2. Chipset of the motherboard.

3. Amount of RAM on the motherboard.

4. Type of CPU, its manufacturer and operating speed.

5. Configuration of the system. Whether are there any 
   other cards in the system.

6. The BIOS version in the system.   

7. VGA card used. 
   The VGA controller used by the card, VGA BIOS version,
   the date of the driver and the revision of the card.

8. Failure codes.

Please FAX all this information to us or CALL our tech 
support and leave a message if you can't get through.
