Glen (and others), I am getting an error when attempting to install the latest Rocks/BioBrew applications. I just downloaded BioBrew-4.1 and Rocks 4.1 cluster iso files: area51+base+ganglia+hpc+java+kernel+sge+web-server-20.10.2005-14.19.12.i386.disk1.iso (from www.rocksclusters.org/) biobrew-4.1-0.i386.iso (froim ftp.bioinformatics.org) I am installing these onto a Pentium IV base PC as the frontend, the same hardware previously ran Rocks 3.3. During the installation, after the rolls are loaded from the CD's there is a message about "merging base distributions". At this point the installation fails with the following message "You are trying to install on a machine which isn't supported by this release of Rocks." This sounds like a hardware issue, but the same hardware was running Rock 3.3. Any suggests would be appreciated. Thanks, John Rux ---------- John J.
