WINE should either read the volume label and serial number correctly from the boot record and FAT file system on the diskette, or should allow us to hardcode the values needed in WINECFG (currently this is allowed for hard disks but not floppies!)
It should be read from the device provided you have the necessary permissions. If it doesn't work despite that, please send me an image of the floppy by private email.
