Table 1565

Format of parameter block for functions 46h, 66h:
Offset	Size	Description	)
 00h	WORD	(call) info level (should be 0000h)
 02h	DWORD	disk serial number (binary)
 06h 11 BYTEs	volume label or "NO NAME    "
 11h  8 BYTEs	filesystem type "FAT12	 " or "FAT16   "
		  (generally CL=66h only, but MS-DOS 5.0 will write the
		  given filesystem type to the disk)
Note:	under MS-DOS 7.0 or a Windows95 DOS box, the volume label field can
	  return as all blanks even when a volume label has been set (the Win95
	  installation seems to blank the volume label field in the partition
	  boot sector; once LABEL has been run, the volume label is reported
	  correctly)
