Disk Format Fails in Enhanced Mode with GSI Drive Controller (101359)

SYMPTOMS

If you try to format a disk either from a virtual machine in 386 enhanced mode or by using File Manager, Microsoft Windows may stop responding (hang) with some drive controllers manufactured by Great Software Ideas (GSI).

In 386 enhanced mode, the File Manager or MS-DOS FORMAT process appears to begin normally, but then the computer hangs and requires a warm boot. The same process works correctly in standard mode.

CAUSE

This problem occurs on the GSI Drive Controller Model 11 with BIOS versions 1.14 and earlier and on the Model 21 with BIOS versions 2.0 and earlier. GSI has confirmed the incompatibility of these BIOS versions with Windows 3.0 and 3.1 in 386 enhanced mode and has BIOS upgrades available.

RESOLUTION

To correct this problem, order the appropriate update version for the GSI Flash BIOS.

   Model  BIOS version
   -------------------

   11     1.15 or later
   21     2.01 or later

You can work around this problem by doing either of the following:

Format the disk using File Manager or MS-DOS in standard mode.

-or-
Quit Windows and format the disk using MS-DOS.
