With this change the MPC750 iMac G3 PowerMac4,1 example boots and runs in *BOTH* non-usefdt mode and usefdt mode. It also means that every PowerMac that I have access to that non-usefdt mode historically worked on now also works for *BOTH* non-usefdt mode and usefdt mode: G3, G4, and G5. Textually the patches would need adjustments to be acceptable for FreeBSD check-in. Also it is possible that some things might have other directions things could instead be taken. But they give solid evidence about what needs to be addressed. Note: There are list messages with notes about other things I ran into while trying to find what would make things work again for both non-usefdt mode and usefdt mode. From what I observe, none are important for this bugzilla (beyond what the various attached patches deal with). -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ [email protected] mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-ppc To unsubscribe, send any mail to "[email protected]"
