J1 is indeed a group of 8 jumpers. You need to remove the jumper between
pins 1/2 of J1. However, the kernel *should* print a message (then exit)
when it starts up if you forget to remove this jumper so I doubt that's
your problem.
I suspect the real fix will be to write zero (32-bits) to address
0xfffc0000 of the NVRAM. This location, together with 0xfffc0004,
specifies the start/length of any RAM present on the VMEbus which is to
be made available to NetBSD. Writing 0x00000000 to 0xfffc0000 using
Bug's "mm" command will disable this feature.
