I have tried something that Dave Evans had done with his
VS3100-M30. After grabbing the 1.3 generic kernel and copying it to /
/dev/sd0a and naming it 'netbsd', setting this first RZ24E to ID 1,
dropping back to the ROM monitor and doing 'B /1 DKA100' at the chevrons,
this is what I got: 

-DKA100

howto 0x1, bdev 0x2a, booting...done. (31448+22260)
>> NetBSD/vax boot [980110 22:29] <<
: rom()netbsd

changing rpb->unit from 100 to 1

 83 BOOT SYS
?4D DEVOFFLINE
 84 FAIL

>>>

What happened or not?

P.S.A
