3e is an unused (invalid) trap number.

Hm.  In both cases you typed "boot disk -s"?  Strange.

What do you have for boot-device, boot-file and boot-args?

Can you try setting fcode-debug? to true and boot with '-sVD' 
arguments so it will stop after loading but before executing the
bootblock.  If the bootblock loads, you can then type:

do-boot " /ofwboot" to execute the bootblock.  It should also
print out what it's doing so you can see how far it gets.
