I have seen IDE cables with a memory so I am not at all certain about the floating detection. > > FILO does look good from what I have seen of it. > > I'm really glad to hear that from you. The one thing I would really like to see is it using the LinuxBIOS table to find motherboard devices. Before falling back to more conventional things like a pci scan. That way you don't need to guess where the hardware is. Right now this is a chicken and the egg problem because that information is not being exported but that is one of the next steps for the freebios2 tree. > > Before anyone can guess anything we need a lot more detailed bug > > report than what has been seen so far. > > > > Steve how does your 1.2G Caviar fail?
