SUMMARY

Compaq DOS MODE allows access to a 132-column mode. This is incompatible with the MS-DOS Editor and MS-DOS QBasic.

When EDIT.COM or QBASIC.EXE are invoked, the top menu bar and the bottom status bars are visible, but no text is visible.

Compaq DOS versions 3.31 and 4.01 allow access to this video mode.

Compaq machines that support this mode are the following:
    DESKPRO 386/20s
    Models ending with n, or l
    New 386/20e and 386/25e with the enhanced video board. To determine which video board is installed, check the serial number plate on the back of the machine.
Microsoft has confirmed this to be a problem with MS-DOS version 5.0, 5.00a, 6.0, and 6.2. We are researching this problem and will post additional information here as it becomes available.
