Hi,

I've eqipped my Mac 7600 with a modern SCSI disk -- a 9GB fast/wide
disk with a 68pin connector and a 68-to-50 adapter.  NetBSD detects
the device fine, and I have an installation on the drive (booted
using the floppy).  However, it would seem that OpenFirmware isn't
so happy, and it doesn't appear to detect it (as bootable).  Here's
part of my OF log where I attempt this boot:

about the devices on the SCSI bus.

Is the problem that OF refuses to deal with SCSI3 devices?  (I had
this problem on my hp300 as well, BTW.)  I may just have to use one
of our old 600MB SCSI1 disks to have a drive to boot from (I wanted
to preserve the contents of the first SCSI disk).

Comments?
