This one didn't succeed either... Sigh... It's clear I'm getting to the /boot/loader program and it's running; it just keeps looping with no indication of an error (until it runs out of heap, which is the assertion failure). Do you know if there's a method of bypassing the loader program and directly booting the kernel? I tried stopping the second stage boot and booting "/boot/kernel/kernel". The boot program spins for a (long) while loading it, but I'm guessing something's missing 'cause once it transfers control to the kernel the system freezes. tfrank> Have you tried 4.9-RELEASE on this system? No, I have several other 5.2 systems (built from these same CDs) and I kind of wanted to minimize the number of variants. This IS the only dual-drive SCSI-only box I have going though... Maybe I should just slap an IDE drive into the box (there's space and even cabling available) and install to that??? tfrank> I understand that 5.2.1-RC2 ISO is also available which might be another option. I know - it came out the weekend after I downloaded and burned the 5.2 ISO. Grrrr.... :-) Thanks! Mike
