hola, i'm upgrading from FC 3 to FC 6 on a supermicro, intel-based, server with SATA disks. When i get to the point where the installation process should ask me if i want to upgrade i get the disk partitioning screen. then when i try to partition disks i am told that there are none! i've tried the upgrade passing the parameters ide-scsi, ide-generic-all & irqpoll (?) in various combinations, but still nothing. the disks are visible under FC 3 and in the BIOS . . . any thoughts? here is my lspci output (network & video have been removed), if anyone finds that helpful. please let me know if there is any other output that would be helpful in diagnosing this issue. thanks a lot, Guy
