Just a quick note: OS 9.2.x had an artificial lock-out for 60x machines, despite having all the support code needed to run still in the kernel. Although with 9.2.x, their lock-out was to remove some key info on how to boot 60x machines properly. Your method will probably lead you to the break-point quickly, although I personally still believe in the possibility of a more subversive lock-out. (And I am waiting on a 8600/200 mobo so I can use this G4/400 card I have, so I understand this user's pain... and I have software I need to fix too) |

It does not appear to be an artificial lock-out, so far as I can tell. In fact, there still is some 604 support code in the kernel. One thing I'm going to try to do is put in some printf's as early as possible, to see if I can narrow down exactly where the problem occurs. Because it does look as though the console gets initialized before the problem occurs, but nothing is printed before everything stops. |

Hmm, I personally would check on the early boot process if you haven't already. Since the lock occurs before any sort of text display happens, that gives a clue as to where it stops. I would check for any early if's in the kernel that do any sort of CPU checking. It may turn out to be an artifical lock-out from Apple to prevent use of OS X on these old machines (of course, they can't lock out the upgrades, since the CPU on those is supported). Or it could be some asm if they use any in the kernel. They might be trying to call a G3/G4-only instruction before all the trap handlers are in place. |

You're quite right--the problem is definitely in the kernel itself. So it may well be painful to fix, for the reasons you indicate. Depending on exactly what the problem turns out to be, there may be a clever solution, but I haven't even found the precise problem yet ... |

Ryan, hate to say this, but it looks like it will be darn near painful to get the 60x series going again. The lockups I was getting while trying were happening in the kernel, not really in BootX or anything else you muck with so far. You would have to probably install a hacked kernel, which would break immediately after the install, and then every time the user updates anything that hits the kernel. |

It can if you have a G3 or G4 upgrade card installed. The original 604 processor doesn't work with 10.2 (it did work with 10.0 and 10.1, however). I want to get this fixed eventually, but haven't figured out how yet. |
