The Sun Fire 4140 is a dual opteron machine. I'm getting BTX Halted and a processor register dump right after it prints the /boot/config -Dp (nothing else printed). Is there any value in trying the -current boot files to boot the 10.3 host? Are they newer? This happened as I tried to move the drives from an older failing host into the sun. The sun will boot a CD/DVD. Can I make a DVD that will boot zfs on hard drives?
