Description:

Mac OS ROM 2.5.1 This Rom allows you to run Mac OS 8.6 (The Earliest OS you can run on this model without the need for emulators) BUT it is specific to only a G4 400Mhz PPC AGP Graphics "Sawtooth" (The Graphite Tower) http://www.everymac.com/systems/apple/powermac_g4/stats/powermac_g4_400_agp.html Having said that, it may work on the 450mhz AGP too. WHY 8.6, you may well ask, the answer is I have some games that only run OS 8.6 You have NO idea, the depths and dark corners of the net I trawled to find this ROM. To Run 8.6 you need: OS 9.x OS 8.6 retail OR Mac OS 8.5.1 AND Mac OS 8.6 Update (Free From Apple.com) Wish I Were... (A Mac Control Panel to change the Gestalt ID of the machine) (http://reviews.cnet.com/8301-13727_7-10341098-263.html) Partition a space on your hard disk or external hard disk for Mac OS 8.6 i) Install a copy of OS 9.04, or 9.2 or 9.2.1 or 9.2.2 ii) Intall Wish I Were... On the Mac OS 9 Side. iii) On the OS9 side Run Wish I Were... iv) Set wish I were to PPC 54xx 64xx v) Restart. vi) Instal Mac OS 8.6 OR 8.5.1 AND Mac OS 8.6 Update After. *Note take care when installing System 8 NOT to update Hard Disk drivers. as it will cause an error. vii) Replace MAC OS ROM from The Mac OS 8.6 Folder with Mac OS ROM 2.5.1. viii) Go to Control Panel System Startup And Select Mac OS 8.6, Restart Voila !

Thank you - I'll try with vMac

vMac only works with a Mac Plus ROM (as it only emulates that one machine). The PowerMac G4 is a completely different architecture. You can use this ROM with SheepShaver, however.

I'll second rspeeds' comment.
The very first G4 PPC AGP 400mhz machines shipped with O.E.M CD's 8.6, but very specifically with it's own ROM (version 2.5.1) Hence I had a hard time finding it.
On another note and off topic, (and no I am NOT trying to promote anything or any site)
If your into old games and anything assocoated with abadonware 6k and/or PPC.
