I have a need to run an old MSDOS 6.22 image with an application that makes use of EMS 4.0.
After some extensive testing, it seems that DOS' EMM386 driver cannot find a 64k page frame that it can use. I can manually designate the block beginning at D800 as a page frame but then shortly after start the system hangs. I have a test program that is used to determine if the system is seeing the EMS as expected and this fails. If anyone is interested in taking a look at this I'll provide the XML for the VM, a config.sys as well as the EMSTEST program which can be used to validate a proper environment. If this is not the right place to raise this issue please point me in the proper direction. Many thanks, Dan Srebnick
