I have an 11/780 with two unibus adapters. On the first unibus I have a dz, a dmf, a 3Com Ethernet controller, and a NSC hyperchannel adapter. On the second unibus I have a UDA50 controller which talks to an RA81 disk. I used to run 4.2bsd on my RM80 disk on the massbus and use the RA81 disk for a user file system. One day we decided to put something else on the RM80 and rig the RA81 as my boot disk for those rare occasions when I would be running 4.2bsd. So I configured a system which knew about all of the devices, but which expected to boot from and swap on the RA81, and loaded the vmunix from that system into the 'a' partition of the RA81, along with the rest of root. Then I tried to boot the new system, using the distributed boot on a floppy I had built according to the instructions in the gen manual and low and behold: ZILCH. The drive online light doesn't even come on. The input I gave the ":" prompt was ra(8,0)vmunix and the system hung. HHHHHHHHHHEEEEEEEEEEEEEEEEELLLLLLLLLLLLLLLLLPPPPPPPPP!!!!!!!! Has anyone booted an ra disk from the second unibus and if so can they give me a hint as to what I am doing wrong? Martin Fouts Nasa Ames Research Center nep.fouts@ames-vmsb ------
