I tried just another unusual operating system today: OpenDarwin.
I installed OpenDarwin 7.2.1 and got some tar errors, but I didn't think
that those errors were a big deal - so I went on normal.
But then I got this message on (verbose) boot process:
Panic (cpu0 caller 0xC0321D8B) unable to find driver for this X86PC
Really strange... I think I cannot handle this, so I should change to another
(broken) system. :-/
After reading a weblog about OS X on AMD64 and saw
that people there has got identically problems there with OS X. I think it's really a problem of supported
hardware, so no big deal to move OpenDarwin to /dev/zero.
Maybe I'll have a try with GNU-Darwin 2morrow. Stay interested. (-:
