I will be attempting another install tonight giving the usb drive thing a shot, as well as seeing if the partition is active. I'm sure I rebuilt the loader with "LOADER_ZFS_SUPPORT=YES", as It wouldn't even boot the kernel before I did this step. Alot of new things to try now, and Drew, I'm with you. I am actually learing alot about the boot process as well.. it just sucks to spend 10 hours in one day to have nothing work. :P Thanks again everyone, I will post back with my results. > > > -- > Be a Great Magician! > Visit The Alchemist's Warehouse > > http://www.alchemistswarehouse.com > >
