I flashed this PowerMac G3 B&W and it's rock solid with OS X 10.4 but I cannot get to boot off Mac OS Classics versions. I tried from 8.6 to 9.2.2 and it stalls with a grey screen. I removed all drives and PCI cards, put back the G3 processor but it can only boot from OS X, so its not a matter of IDE/master/slave thing. I tried also to boot of an HD where I had installed an universal version of 9.2.2 and it stalls at the grey screeen.
Any ideas?
