I have Asus P5AD2 motherboard with 3 hard disks mounted on IT8212 RAID controller. When I try to install Suse 9.1 it says that no hard disks available. How to fix the problem?

Weird. Are you sure the hardware is set up right?

Check the BIOS, particularly for LBA settings for the drives.

I’ve got two HDs connected via IDE, master has 250 GB and winxp on it and slave has 40 GB and im trying to putsuse on otherwise it’s completely empty. The installation detects neither but I know both work fine and are connected correctly through checking in windows. Help

What are your LBA settings in BIOS for the drives?

As of the 2.6 kernel a lot of RAID chipsets are not supported, and I'v found that with some if you have a hardware RAID setup SuSE 9.1 doesn't even recognize that there is a HDD installed. THIS site has a list of SATA RAID devices and what level of support they have under the 2.6 kernel. You'll note that a lot of them, especially the cheaper ones found built into MoBo's are supported only in a software RAID configuration. I know this site is only SATA but I suspect the same thing is true with PATA RAID configurations as well. PhoenixRS if you have an extra HDD that is not in the RAID setup you may try unpugging the HDD's in your RAID setup, plug in the extra drive and turn off hardware RAID and see if the installer sees the drive, if it does than SuSE has drivers for your hardware but it is not supported in a hardware RAID configuration.
