SYMPTOMS
After upgrading to MS-DOS on a Leading Edge Model M 8088 or a Sperry HT 8088 computer, executing QBASIC or EDIT may produce unusual video display behavior (for example, horizontal scrolling or blinking) or unusual system behavior (for example, lock-ups).



CAUSE
The Leading Edge Model M and Sperry HT are 8088 machines. They originally shipped with a color video controller that does not conform to any standard supported by MS-DOS 5.0 and later (that is, monochrome, CGA, EGA, EGA mono, VGA, or 8514).

The products included here, Leading Edge Model M and Sperry HT, are manufactured by vendors independent of Microsoft; we make no warranty, implied or otherwise, regarding these products' performance or reliability.
