It is possible that the sata-promise driver doesn't have IDE support in it. Also what mode is the Promise controller chip set in (ie RAID or Ultra IDE)? If in RAID you have problems. The sata-promise driver doesn't do the RAID mode but interacts with the promise chipset in Ultra IDE mode instead. Thus any RAIDs you set up under FC2 have to be Software RAIDs (unlike those the non-free Promise linux Promise RAID driver used for Linux 2.4 kernels). This means that you will not be able to do a dual boot Windows/Linux machine which has Windows Promise RAID enabled. If a Windows Software RAID existed you could use that with the Promise non-RAID Windows drivers but I don't believe such a beast exists. Howewver if you are only going to attach a single drive to the IDE you might as well use the Ultra IDE mode in the Promise BIOS settings. I have been install FC2 on a machine with a motherboard Promise RAID SATA chipset attached to two identical SATA drives set in Ultra IDE mode (using a software RAID 1). It was been working perfectly.
