Based on my testing, it appears that bondi refuses to boot Mac OS 8.6 or later. The system hangs at the Happy Mac icon.
I believe I have narrowed the issue down to the (boot, 3) resource in the System file. The lock-up seems to occur right as the Mac OS ROM NanoKernel v1 is replaced with the on-disk NanoKernel v2. Coincidentally, I believe Mac OS 8.6 was the first version to introduce this mechanism.
