Since the Gigabit shipped with 9.04 your retail 9.1 CD should be fine. I own the same CD which came with my Jaguar Retail kit, it's been fine for the most part, however sometimes booting or installing has been "problematic" for unknown reasons. I've been the "Big System Morsels" error more often than "Unimplemented Trap", but I've seen both. You may have seen this Apple KBA: <http://docs.info.apple.com/article.html?artnum=18999> It says Unimplemented Trap can be "spurious" which I think means "keep trying"? I think I've had this happen once before, and I can't remember what I did, perhaps shuffle RAM or something, but since these can be "spurious" perhaps my solution was just luck? Since OS 9 needs hardly any RAM you might try a single stick? I'm assuming you're using a separate HD for OS 9 since you're talking about swapping? I think this is best myself, I hate mixing OS 9 and OS X on the same HD, but if you can't get going perhaps you could try the NetBoot OS 9.2.2 that installs from OS X. You'd need to have both HDs in the Mac together and make sure you add the OS 9 drivers to the OS 9 HD before installing, and also remove the two netboot extensions. Theoretically this should give you a bootable OS 9.2.2 System. Here's the link for the Netboot 9.2.2 download if you decide to try it: <http://docs.info.apple.com/article.html?artnum=120243#English> I'd try the 9.1 CD again before giving up. Big hassle for firmware upgrading, eh? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed Low End Mac's G3-5 List, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
