FC1 DAC960 worked for me (Mylex 352), but FC2 test1 doesn’t. It loads the driver OK (and a dmesg shows it sees a logical unit) but the installation process says there are no disks. It asks if I want to load a driver, I say yes, and there’s my DAC960 already loaded. Dmesg talks about registering /dev/rd/c0d0 but I see no such file.
Homebuilt Athlon 1333 machine, Mylex 352 with 2 36GB disks striped as 1 logical 72GB volume.
