Focus on solving the problem. 8) As a totally different solution, how about using NFS booting. You could setup a server box with good quality disks in a good air flow case and NFS boot all of the other boxes. With 100Mbps ethernet you should get reasonable performance. Even 10Mbps should be better than CDROM given the poor seek times, although sustained transfer speed will be less. Matt Dillon at www.backplane.com has info on how to do this.
