Identical to the one I have (I bought it off e-bay 'cos it was cheap and I
can flash the BIOS to defeat the regaion protection...)

Interesting as I thought that limitation was UFS based not the OS virtual
filesystem interface (it does, as you say, handle massive NFS partitions
after all)

I did notice that a bus scan iin cdrecord did only identify it as a
CD drive - which surprised me as I would have thought that as it used
the raw SCSI to identify the drive it would have seen it as a DVD
independend of the OS.

That an interesting thought. My first attempt was going to be a simple ISO
image onto the disc - one under 650MB just to make sure that it would read
an ISO image from a DVD, and then do smething a little larger. Id also like
to see if these read in Windows too. I dont want t re-archive everything onto
a media that can *only* be read by OpenStep after all !

anyway, i shall try and have a go in the next week or so and let you know
what I find. Cheers,
