Sorry my bad. I just played with Minix a bit some time ago. You seem to be more informed then me. :)

Btw, I had success running the recent versions in qemu. That is without VT-X (sadly).

You have penguinofobia. :D

It seems to work fine. At least with what I tested. What problems did you have? I'll test it more and let you know. I did a several quick tests. Nothing too thoroughly.

I don't know. Won't play with that soon. I can't seem to get word/bit/etc definitions for 16-bit right anyway... It seemed to work fine with a simple example. But with something other than that... Still have to test.

But yes. It seems to work fine when LFN driver is loaded. Otherwise it still tries to use LFN. But that that's my experience with only one package (small untar utility) so it may be generalization.

I haven't look much into it. But it seems like a "no so easy task".

Bookmarked. :) I'll check out his lcc. Good idea for a more detailed test.

What's wrong with ld? Can it be built with Deitmar's lcc build? Have you tried any other linker with COFF support (just brainstorming)?
