Please get natsemi.tgz from ftp.torque.net/pub. Dave Campbell wrote the
program in that file - it should set your port in EPP mode. If I recall
correctly, you just compile the program and run it as root.

That _is_ curious. What mode does the epat driver use with the SparQ ?

Good. If all else fails, I'll get you to do some i/o traces for me.

No, that's not what those numbers mean :-(

I've forgotten, did I ask you to see what happens if you force the port
delay to 4 ? Please try this and let me know.

There's no mystery here - the MSI unit number is used to distinguish multiple
backpack drives on the same port. It has nothing to do with the Unix device
number. You can put it back to the original number and it won't make the
slightest difference to bpck.
