I don't expect to see this in 6.0-R. Now that you provided a solution for this problem it's ok.

Thanks anyway. 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. :-) Regards, Johny.
