Cannot Run MS-DOS Apps When Booting from Jaz Drive

• Microsoft Windows NT Workstation version 4.0
• Microsoft Windows NT Server version 4.0

SYMPTOMS

If an Iomega Jaz drive is configured as the boot device, and you attempt to run an MS-DOS 16-bit application, you get the following error:

   Config.nt The system file is not suitable for running MS-DOS and
   Microsoft Windows Applications.

CAUSE

The pagefile cannot reside on a removable drive. This is by design. Regardless of how the drive is configured in the SCSI controllers BIOS, the system still knows that the drive is removable.

WORKAROUND

To work around this problem, relocate the pagefile to a fixed disk. If no fixed disk is available, the application cannot be run; the system cannot be made to run 16-bit MS-DOS applications.
