All up and running on internal drive partitions, no sound, sleep, networking, gfx accel. Running in Millions of Colors at 1920x1080. I didn't realize older OS versions could even do that!
Not sure when the next time is I'll get to hack around, but if I get some spare time between now and the end of the year, I'm going to try and hack together an enabler that pulls necessary resources from various OSes to get something stable and functional (memory fixes, HFS+, networking) and a package of other necessary extensions and panels.
I do wonder whether there are ndrvs used in the OS X context that could be rolled into the Mac OS ROM and enable the other broken bits we see in Mac OS 9 and earlier. Seems to me all the pieces are available now, if we know where to look and how/in what order to assemble them.
I also want to see if I can hack something together to get OS 8.5 through 8.6 booting properly.
Oh and in my case, all of this is on a late 2005 Mini. Experiences should be similar across the different G4 Minis though.
Plus, it was quite humourous to see my 1GB RAM actually being properly displayed on Mac OS 7.6.1 -- with the System taking up 512MB of that. That means running 7.6.1 with 512MB of RAM available for apps and RAM disks
One other thing: just to see if I could: I formatted a 4GB USB stick with 2 2GB HFS partitions. I can read/write them in 7.5.0 and later, but can't boot from them. Disk Tools says the device can't be managed by it, but Disk First Aid is able to format the partitions just fine.
