Opensuse 11.0 Beta 3 : No Go With Hp Dc7800

(it's mostly built from laptop hardware)

machine 1 has only XP installed
machine 2 has XP and OpenSuse 10.3 installed

both machines report : no harddisk found in early stage of installation

tried installation from internal CDRW/DVD read only and external DVD-writer, no way.

booting 11.0 Beta 3 from live CD KDE was no problem

installing 10.3 from DVD was no problem

need more information, sent me a mail.
