My research will be mostly development and to test how I can switch

dev tools provided in packages as they often return DOS16/m exceptions
and hang the computer out.
With this I have few starter question as a user:
- DOS16/m is a 16bit protected mode extender. Does it mean that
FreeDOS runs in 16bit protected mode from the command line or perhaps
some driver is interfering or rather the iMac I use has hardware that
may cause some obvious incompatibilities.
I'm happy to dedicate some time for further testing and even debugging
but I need some hints how to start. Will somebody here be available to
assist me a bit with starter points?
Well, while doing some research for a totally different project, I came
about some notes stating that there might be issues with some versions
of SMM BIOS that allow to enable "legacy mode" to handle USB peripherals
(keyboard, mouse), which could result in problems switching into "long
mode". Could be that your HackinDOS machine as such issues that cause
the errors/crashes you mentioned...
