QAPLUS 4.21 Produces Errors with EMM386.EXE (76788)
The information in this article applies to:
• Microsoft MS-DOS operating system 5.0
• Microsoft MS-DOS operating system 5.0a
This article was previously published under Q76788
QAPLUS version 4.21 DMA tests do not operate correctly when EMM386.EXE is
loaded. Errors vary based upon machine type, but when running the DMA tests
the system may reboot, stop responding (hang), or never complete the DMA
tests. This is specific to an interaction between EMM386.EXE and QAPLUS.
Removing EMM386.EXE from the CONFIG.SYS file alleviates the error
If EMM386 is loaded under MS-DOS version 5.0 (parameters unimportant) and
Windows 3.0 is running, a QAPLUS DMA test will reboot the system or it will
lock it up (preventing a CTRL+ALT+DEL reboot).
