You can also see this kernel message: PCI_IDE: unknown IDE controller on PCI bus 00 device f9, VID=8086, DID=266f Which I would guess is at the root of the problem. Maybe you should try a 2.6.x kernel since it does contain newer hardware drivers than a 2.4.x kernel. >I presume that there is some parameter that needs to be set in the kernel >build, but I have not been able to figure it out.

Usually most of the ide controllers are added to the kernel since it is a very common device on many PC's. The command "lspci -vv" would also try to identify PCI hardware. >Thank you very much, > >David Boulware > regards, Earle
