I was specific.  Trying to access dw3 disks gives error #221.

Both boot floppy's are IDENTICAL except for the /DD device!
As i said.  setting the /dd device to point to /x0(dw3 device) i can 
access both scsi and dw3 devices.
Setting the /dd device to point to /s0(scsi disk) the dw3 devices cannot 
be accessed and give #221 error.

If something was missing from one boot floppy it would have to be also 
missing from the other!

Both boot floppy's are made from the same nitoros9 boot image.  So if 
one has bad content so does the other!

And as I said I examined both boot floppies and they are identical 
except for the /dd device.
And all modules are in the same exact order on the os9boot file.

By the way I used image nos96809l2v030209cc  which as been around 
forever and stable.
and I dsave'd the content of it to the hard drive, so the /dd contents 
are identical.

The tc3 drivers/devices came from the Cloud9 Superdriver disk, as they 
are not on the nitros9 dist as far as I can find.

I wasn't expecting it to be trouble-shot, just curious if similar 
symptoms have been observed by others.

Cheers :-)
