(Although the twin folks would like this [as, I'm sure, would terry ;)], so it may be working.) It's also an x.out program, which currently does not load (I wrote an x.out loader, once, but x.out programs wouldn't work; I don't know why). Lastly, I have been unable to find any documentation on the '286 x.out ABI, which makes things difficult. (For one thing, they don't use FP instructions, they have some sort of trap, or some of them do, anyway. I'm not sure how they enter the kernel. Things like that.) Running '286 programs would also be done differently from running a '386 program, as the "best" way to deal with it is to write a wrapper program that intercepts and translates all the system calls and arguments (otherwise, in the kernel, each system call has to check for whether the program is 16- or 32-bit -- unplesant). >What worries me more is that I can't even run a 'normal' SCO executable such as >'ls'.

It needs that as well, I believe. Sean.
