Hello again: Thanks to Steve and Bryce for their suggestions on my system freeze/install hang problem. The initio SCSI card did seem to be the problem. I removed it and was able to install Mandrake 9.1. I put it back in and Mandrake 9.1 did not recognize it. On the one hand, I'd like to access my Jaz drive. On the other hand, the system is stable... Vaughn
