Actually no. I must say that it looks ugly to me.

The fact is that linuxboot ROM and extboot ROM are about different
things, and they only share a bit in that they both intercept int 19.

I very much like the the Unix principal, that is "Does one thing, and
does it well", so I prefer to have 2 independent ROM: one to boot
Linux, and one to do external boot. I see no problem that we have more
than one ROM, and these two can be independently loaded into the
memory.

So I think I agree with Peter here.

Thanks,
