CD
The prefered syntax is the drive letter (e.g. d:'). The alternate syntax\.\d:' is supported. `/dev/cdrom' is
supported as an alias to the first CDROM drive. Currently there is no specific code to handle removable medias, so
it is better to use the change or eject monitor commands to change or eject media. Hard disks Hard disks can be used with the syntax: `\.\PhysicalDriveN' where N is the drive number (0 is the first hard
disk). WARNING: unless you know what you do, it is better to only make READ-ONLY accesses to the hard disk
otherwise you may corrupt your host data (use the `-snapshot' command line so that the modifications are written in
a temporary file).
