I am having similar wierdnesses with my 3/260.

I have SunOS installed on sd0, a Fujitsu 530 MB.
NetBSD is installed on sd1, a Quantum 105.

SunOS boots and runs just fine.

I cannot boot from the Quantum.  b sd(0,8,0) simply sits there for 10 seconds,
then returns me to the boot monitor.  I have /boot on it, and I did
installboot.

If I netboot NetBSD from my boot server (my Amiga 3000), then si0 is found,
and the Fujitsu drive is found fine, but the Quantum is found at multiple
LUNs!  Worse, the geometry strings read from the Quantum differ for each
LUN!  The Quantum drive worked fine under NetBSD/Amiga, and it works fine
under SunOS.
