POWER3 / IBM 7028-6E1

[Любомир Григоров]

Hello Nathan and list members, I am trying to revive this issue as it
became stale for over 3/4 year. For some reason my reply to the PR (
http://www.freebsd.org/cgi/query-pr.cgi?pr=powerpc/164225 ) was not
published. Therefore, I include Nathan's comment and my reply at the bottom
of this e-mail.

I tried 'printenv' to see where load-base is mapped. Milas Obuch suggested
I remap it with 'setenv load-base 0xABCDEFGH' to the real location, but I
don't know what to set it to.

Also, I tried booting 9.1-RC2

I think this is what you needed, if not, please tell me :) BTW, I have 2x
256MB chips.
