Well, I have. I was part of the team that reviewed and exported that
code for open source. Although the motivation was more a matter of
making the source readable than buildable. That was back when we were
Sun, Oracle doesn't do this kind of thing.

Yup. Generally, you run the tools/Makefile first, which builds pieces
the individual platform builds will need. That's now an automatic part
of ordinary builds, although I don't think it was back then. Once you
have tools built, you go into arch/sun4v/ontario/release/ and make
there. That should produce an openboot.bin.

Are you running Solaris 10 or later? You might try under Solaris 9 (the
release that was current at the time we shipped it), there was a
disagreement between Solaris and Openboot's assembler code on use of a
couple of the %g registers. This caused openboot builds to break in
Solaris 10. I believe this build was snapshotted before we fixed that.
