Looks like my initial problem was do to a
bad floppy. I've connected a different floppy
drive and the boot progresses a little further.

>>>boot dva0
block 0 of dva0.0.0.0.1 is a valid boot block
reading 15 blocks from dva0.0.0.0.1
bootstrap code read in
base = 1f200, image_start = 0, image_bytes = 1e00
initializing HWRPB at 2000
initializing page table at 1e4000
initializing machine state
setting affinity to primary CPU
jumping to bootstrap code

NetBSD/Alpha Primary Boot
Jumping to entry point...

halted CPU 0

halt code = 5
HALT instruction executed
PC = 20004000
>>>


Any ideas or suggestions would be greatly appreciated!

Thanks!
