Q27925: EGA and VGA Graphics Are Not Supported in OS/2 Protected Mode
Article: Q27925 Product(s): See article Version(s): 6.00 6.00b 7.00 Operating System(s): OS/2 Keyword(s): ENDUSER | | mspl13_basic Last Modified: 31-JAN-1990 EGA and VGA graphics are not supported in Microsoft BASIC Compiler Versions 6.00 and 6.00b and Microsoft BASIC Professional Development System (PDS) Version 7.00 programs in the protected mode of OS/2. (Note also that COLOR is ignored in SCREEN 1.) The BASIC compiler talks directly to the hardware to perform EGA or VGA graphics. Applications that sit in OS/2 "ring 4" are not allowed to perform EGA or VGA graphics in the protected mode of OS/2. If the application needs to talk to the hardware, it must go through a device driver. There is currently not a device driver for EGA or VGA graphics in OS/2 protected mode.
