Thanks, > -Nathan Nathan, It's been a while since you've sent the email out, but I just wanted to let you know that I can't even seem to get a Powerpc snapshot CD of 8-CURRENT or 7-RELENG to boot on my Mac box -- basically the console "dies" after the first initial set of messages come up from the kernel. The input right prior to this line (DDB blah, KGDB blah) is displayed, but this isn't: Copyright (c) 1992-2008 The FreeBSD Project.

FreeBSD 8.0-CURRENT #0: Mon Aug 18 21:49:28 PDT 2008 I tried the June and July 8-CURRENT snapshot CDs and the July 7-RELENG one. Do you try and grab any params from OF by chance? My settings are intentionally goofed up for a reason :) (I typically boot from a target firewire drive attached to the box). I'll gladly give you more specs if you need them, but it's a G5 1.8GHz UP with 4.0GB DDR2 667 RAM. Thanks, -Garrett
