               Drive labels and serial numbers with wine
               -----------------------------------------

       Until now, your only possibility of specifying drive volume labels
and serial numbers was to set them manually in the wine config file.
By now, wine can read them directly from the device as well. This may be
useful for many Win 9x games or for setup programs distributed on CD-ROMs
that check for volume label.

WHAT'S SUPPORTED ?

    *  FAT systems (types 'hd' and 'floppy'): reads labels and serial num's.
    *  Iso9660 ('cdrom'):                     reads labels only.

HOW TO SET UP ?

	Reading labels and serial numbers just works automagically if
you specify a 'Device=' line in the [Drive X] section in your wine.conf.
Note that the device has to exist and must be accessible if you do this,
though.
If you don't do that, then you should give fixed 'Label=' or 'Serial=' entries
in wine.conf, as Wine returns these entries instead if no device is given.
If they don't exist, then Wine will return default values (label "Drive X"
and serial 12345678).

Now a seldom needed one:
If you want to give a 'Device=' entry *only* for drive raw sector accesses, but
not for reading the volume info from the device (i.e. you want a *fixed*,
preconfigured label), you need to specify 'ReadVolInfo=0' to tell Wine to skip
the volume reading.

EXAMPLES

*** Simple example of cdrom and floppy; labels will be read from the device on
both cdrom and floppy; serial numbers on floppy only:

[Drive A]
Path=/mnt/floppy
Type=floppy
Device=/dev/fd0
Filesystem=msdos

[Drive R]
Path=/mnt/cdrom
Type=cdrom
Device=/dev/hda1
Filesystem=win95

*** CD-ROM. We want to override the label:

[Drive J]
Path=/mnt/cdrom
Type=cdrom
Label=X234GCDSE
; note that the device isn't really needed here as we have a fixed label
Device=/dev/cdrom
Filesystem=msdos

TODO / OPEN ISSUES

 - The cdrom label can be read only if the data track of the disk resides in
the first track and the cdrom is iso9660.
 - Better checking for FAT superblock (it now check's only one byte).
 - Support for labels/serial num's WRITING.
 - Can the label be longer than 11 chars? (iso9660 has 32 chars).
 - What about reading ext2 volume label? ....
