Yes. > Is the IDE-Driver working without the PCI ? (Or does the > ux-Configration not supporting an physical harddisk ?) The IDE controller in a PC is (usually) always a PCI device. So no, it will not work without PCI. The UX configuration is an L4Linux config that has been configured to not use any physical hardware.

An IDL compiler is good to have but also requires considerable work for the tool itself. It has been found out that C++-based stream operators hide the most annoying work on marshalling/unmarshalling and behave well on the performance side as well. The IDL compiler still has other benefits but needs to be done and maintained. Adam -- Adam [email protected] Lackorzynski http://os.inf.tu-dresden.de/~adam/
