Previous releases would boot only sometimes, otherwise I'd be getting a hang or a crash. The frequency of the boot problems seems to increase dramatically when I boot from the hard-drive, but with 11 it has never booted correctly. I wasn't the only one seeing this type of a problem and I remember seeing a thread about it a while back. Mark Millard reported it, and someone has tracked it down to some register getting (unexpectedly) clobbered by the open firmware. I was hoping this had been fixed, but it seems that things have only gotten worse... :( CCing Mark---maybe he will know more about this. -Krzysztof
