Re: [Freedos-user] 64b Dos Extender Outline
Hello, I'll give you my opinion. Perhaps more than facing on features, I see two foreseeable problems. (1) If computers are ever to boot on a 64-bit world with EFI instead of BIOS, I guess that there would be a kind of 16/32-bit API for maping BIOS into EFI, otherwise that is key to FreeDOS (or I am completely mislead). (2) DOSers are probably likely to use EMM386, what about interoperability or even some kind of emulation/mixture? Probably thougher topics than it seems.

DXF (or Drawing Exchange Format) is a common file format between computer-aided drafting programs, such as AutoCAD.
