non-DOS (yet): an interesting project for x86-64 (Miscellaneous)

OK, there is way to switch to RM and back but question is that UEFI runtime services are compatible with it and how many time it takes this overhead (saving context, etc) when switching back and forth too often. I guess that once you switch to RM and change some HW state then it will mess up UEFI when you switch back. I don't know if UEFI design was count with such option in it's architecture.

BTW on MBs without CSM it is still a possibility to compile opensource SeaBIOS as CSM and do BIOS mod to insert it in. But I didn't read any success story about it yet.

BTW2 maybe it would be easier to compile DosBox(X) as a native UEFI application that will use UEFI SVGA, input and storage drivers that you can select at boot. Of course it wouldn't be real DOS but I guess UEFI env. is some closer to linux so porting would be easier than messing with all the low level and sometimes undocumented stuff needed for real dos64. An it remembers me there already was/is RDOS project that is not much discussed anywhere - at least it contains some attempt to handle ACPI. But I was unable to boot it on my PC.

DOS gives me freedom to unlimited HW access.
