Has anyone successfully upgraded a RedHat linux box that was running the non-free Promise RAID drivers (using the bios level RAID support) to Fedora Core 4? My understanding is that the dmraid package should be able to parse the tattooing of the hard drive that the Promise RAID non-free driver uses such that anaconda can find and use those RAID partitions without losing the data. We have a RedHat 9 box which was installed using those non-free Promise RAID drivers and I would like to be able to upgrade it to FC4 without reformatting the drives. Thanks in advance for any feedback on this. Jack
