You might try slowing things down to 5MHz though... David is right: the 174x is a known pain in the b*tt for newer/faster drives. It is very sensitive to the 'cleanliness' of the SCSI bus, for instance you should not use an external and an internal cable on the same board at the same time. Some people get away with it, for others it is the kiss of death. I have FreeBSD 2.x running with 1740 successfully, but only with non-fast drives. 274x boards tend to be quite a bit better Wilko _ ______________________________________________________________________ | / o / / _ Bulte email: wilko @ yedi.iaf.nl http://www.tcja.nl/~wilko |/|/ / / /( (_) Arnhem, The Netherlands - Do, or do not.
