SUMMARY
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 condition.



MORE INFORMATION
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).
