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). |
