[NTVDM]
Read global settings from the register (in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\NTVDM ; note that this is a ReactOS-only configuration key, because no equivalent functionality exists on windows), and currently initialize: - the BIOS and ROM files to be used; - the hard disks to be mounted at startup (they cannot be unmounted at runtime, contrary to the floppies) (maximum 4 hard disks). svn path=/trunk/; revision=69390
