| Btw if you hack it that way, does it work? Or does it get any farther?

Vitaliy, as bernd already has said, it make the game start much faster...

So I suppose it helps, but I doubt we should be making this change for all
unhandled NtFsControlFile functions.  
Bernd, can you try adding two required cases to NtFsControlFile(), namely
FSCTL_LOCK_VOLUME and FSCTL_UNLOCK_VOLUME, and set return status only here?

But we don't know whether Tiberian Sun is referring to the drive c: .  That's
why I was asking about a way to get description of an object pointed by the
handle.  BTW, thank you for your nice explanation, Vitaliy.

IMHO, we still could detect tries to lock CDFS (device type
FILE_DEVICE_FILE_SYSTEM being compatible with a FILE_DEVICE_CD_ROM_FILE_SYSTEM,
not with a FILE_DEVICE_DISK_FILE_SYSTEM), then we could check whether running
linux kernel keeps appropriate CD device locked and if so--we could return
STATUS_SUCCESS.  No?

Bernd, does the game use real CD during its start?
