I won't have much time to work on this stuff for a while, so I thought I might as well post it here. I've got a ntoskrnl.exe that can load, unload and initialise drivers successfully (Well, I've only tried with a few builds of safedisk but that doesn't matter), it can also dispatch io requests received from DispatchDeviceControl to the driver. However safedisk fails by returning STATUS_UNSUCCESSFUL in the IRP's IoStatus.Status member, I haven't been able to debug this because winedbg refuses to step trough the code properly, however I will try again when I have time to do so. In the mean time you can download and build this stuff yourself, the patch that teaches wine to interact with ntoskrnl is at http://spazioinwind.libero.it/nonsolomicrosoft/public/patch.diff , ntoskrnl itself is here http://spazioinwind.libero.it/nonsolomicrosoft/public/ntoskrnl.tar.bz you'll also need http://spazioinwind.libero.it/nonsolomicrosoft/public/ntoskrnl_protocol.h , put it in include/wine. A full ./configure && make depend && make is needed to build this stuff into wine after patching. Comments/ideas/fixes welcome. Note that ntoskrnl isn't thread safe ATM and probably can't handle more than one driver at any one time.
Ivan.
