The arguments hd, sect=8, ssize=1024 and cyl=77 sets the floppy drive to use high density MFM-encoded floppy disks with 77 tracks – each track consisting of 8 sectors, each 1024 bytes long. # setfdprm /dev/fd0 sect=8 hd ssize=1024 cyl=77 Assuming that you have installed fdutils, type the following command after the floppy disk has been firmly and correctly inserted. If you have more than one floppy disk drive or have chosen to set the drive 5.25" as drive B, use /dev/fd1 instead. Assuming that the floppy disk drive is the first drive (drive A), the device file for this drive is usually /dev/fd0.
