... It supports quite a lot types of harddisk controllers (including the A590, ofcourse) where it uses a complete partition of the drive. It also makes use of extra ram and turboboards on your A500. A turboboard significantly improves videospeed, extra ram can be used as EMS/XMS compatible memory. I don't know if it works with all turbo boards, as I never tested this myself.
I wonder if it is compatible with Supra's 500XP and with their Turbo28?
Has anyone tried FreeDos?
