Well, looks like you're the 1st person with a Magnum to run NetBSD/Amiga.   
When I gave Michael the code to get the Magnum up and running, I no longer  
had one to be able to actually test the code on.  You're the guinea pig ;-).

I would think that the C710 is not being configured correctly.

>My hardware configuration:
>   Amiga B2000 box with CSA 40/4 Magnum 68040 accelerator/disk controller
>   Micropolis 1.7 GB hard disk (Unix partitions in last 556 MB)
>   32 MB of 32-bit FASTMEM and 2 MB of CHIPMEM
>   Nexus disk controller with SyQuest 88 MB removable and DAT backup
>              tape drive attached

I thought I gave the Nexus information to Michael, but I guess I didn't.   
This will probably make it into Release 1.1 :-(
