   Cis1284.386 from Canon Multipass
   Lex01.386 from Lexmark
   Lexsw2.386 from Lexmark
   Mpass.386 from Canon Multipass

   Sumovmi.386 from Panasonic KXP-6100 laser printers
   Vcpd.386
   Vecpd.386 from Netscape Navigator
   Hpypeppy.386 from Hewlett Packard

RESOLUTION

To resolve the problem, follow these steps:

Click the Start button, and then click Run.

Type the following line in the Open box, and then click OK:
system.ini

Locate any of the following lines in the [386Enh] section of the file, and then remove or disable the lines:


    - DEVICE=<path>\Cis1284.386
    - DEVICE=<path>\Lex01.386
    - DEVICE=<path>\Okiport.386
    - DEVICE=<path>\Sumovmi.386
    - DEVICE=<path>\Vcpd.386
    - DEVICE=<path>\Vecpd.386

NOTE: To disable a line, place a semicolon (;) at the beginning of the line.

On the File menu, click Save.

On the File menu, click Exit.

Shut down and restart your computer.

If the problem persists, repeat steps 1-2. Disable any lines in the [386Enh] section that list a driver with a .386 extension, and then repeat steps 4-5.
