How might I make ld produce an absolute runtime image, ie a binary
file already relocated, just requiring copying to the given address
and executing?

I am hoping to make a kind of Linux-kernel-like bootstrap, where the
realmode strapper loads an image from disk into the first 640k,
switches into protmode, and jumps to it.

The realmode loader is not a problem.

It would be nice if I could use gas and C to write my image! I know
the runtime libraries and all that will be completely useless, but
hey, we're not trying to do anything complex!

Regards,


ABW
