I don't expect to see this in 6.0-R. Now that you provided a solution for
this problem it's ok. I am satisfied with this, but I am thinking that in
the future it would be nice to provide such an "out of the box" solution with
the ISO.

Ok. Thanks for your help. I am really happy with it because my U1 is now
usable with the onboard SCSI + HME SBUS network card.
I also have to thank Scott for porting the esp driver. :-)
