Yah, that is one of the valid IDs for the SCSI card.  See sys/arch/ 
hp300/dev/diodevs

Man, you're really making me dig deep to remember this stuff :-)

That's certainly possible.  What model is your machine?  Rev A  
BOOTROM + 68020 ... is it a 320?

Only the later BOOTROMs had the boot device selection menu.  Any  
system that has a local/remote switch for the console as a piece of  
hardware (DIP switch) is not going to have the boot device selection  
menu (because that menu also contained the software version of the  
local/remote switch).
