SUN, I have an A3500. I have replaced the disks in slots 0,1 and 2 with three 36GBT disk of my own. I am trying to boot from slot 0 but the system is not seeing that disk. When I run 'format' I see slots 1 & 2 ... I have heard that a large boot disk might require a patch or firmware upgrade...? Any ideas on this situation.. Regards, Wlfpck92 at aol.com
