============================================================================= AST RESEARCH, INC. TECHNICAL BULLETIN #0743 01-24-92 ============================================================================= AST PREMIUM EXEC 386 AND HEALTHDYNE SOFTWARE PROBLEM: When the Healthdyne database software accesses the math co- processor in a Premium Exec 386/SX-20 the following error message "Stack Frame Error" displays and then returns to a dos prompt. AFFECTED SYSTEMS: Premium Exec 386/SX-20 and Premium Exec 386SX-25 CAUSE: The software when started with a batch file "GO 1" mis- identifies the L.C.D. screen and the environment created is incorrect. The correct environment is created by the software if the screen is identified as color CGA, EGA, or VGA display. SOLUTION: Revision "B" of the software has been released by Healthdyne that detects the display attached thereby correcting the above problem. A temporary solution is to start the program with the "GO 2" batch file, which identifies the screen as a VGA display.
