Help!,

I've successfully installed and booted MacBSD 2.1 on my DUO210.
And have no problems booting into multi on the internal SCSI
drive.

I am now trying to get my Zip and, better still, my Jaz drive
working (mountable). But I've hit a small (read BIG!) problem...

I am able to partition the drives using HDT Primer and further
I have created A/UX Usr (and I tried Root) partitions on both.

I was able to successfully run mkfs 1.4 (which detected the drives
on scsi 1 and scsi 6) to create BSD4.3 filesystems on all the A/UX
partitions I created. No problem there.

I booted MacBSD and attempted to mount the new drive(s) with

  mount /dev/sd6g   (I tried 1g, 6g, 1d, 6d )

and all I got was

   ffs: /dev/sd6g on /usr2: Device not configured (for example)

I then re-booted the machine and... MacBSD bootup does not detect
the Zip or the Jaz drive !

With a MacOS partition on the disks I do get the eject behaviour,
but pudshing the disks back in doesn't make any difference. I've
tried with brand new disks, only the Jaz plugged in and only the
Zip plugged in. I have tried with zip/jaz disks containing the FWB
driver, the native Iomega driver and both. No luck.

I am using a kernel which was specifically for the DUO230 and
I suspect may be a little out of date ?

What I cannot understand is how the mkfs mac utility can detect
the drives, yet the kernel can't. Looking at the bootstrap output
I noticed the following...

   obio0 at mainbus0
          :
   ncrscsi0 at obio0
   scsibus0 at ncrscsi0
   sd0 at scsibus0 targ 0 lun 0: ... (which is my internal drive :)
   sd0: 244MB ...

which is fine, but I also found:

   nubus0 at mainbus0
   macvid0 at nubus0: Macintosh Duo MiniDock
   macvid0: 640 x 870 ... (which is the external videoport on the dock :}

does this suggest that the external scsi devices may be on nubus0 rather
than obio0 (because they are plogged into the socket on the dock :| ?

Having trawled the net, I did find something mentioning a similar problem
with a duo on a Microdock. The author mentioned the term 'nubus scsi'.

So anybody got any ideas/solutions/fixes/instructions etc. etc. etc ?
