Correct. It would be a good deal of work to boot FreeDOS that way. Alternatively, it might be easier to just create a custom “Thin” version of linux to host a VM using QEMU or DOSBox. Then run FreeDOS under that VM. Although performance would not be as good as running on bare metal, it solves several other issues. For instance, network and sound cards could be supported through the linux host providing generic support under DOS. Although less work, that is not a small task to create or maintain either. They are the primary reasons there is only BIOS support at present and for the foreseeable future. Maybe someday. But, not likely anytime soon. :-) Jerome _______________________________________________ Freedos-user mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/freedos-user
