fdc driver provides support for the NEC 765 floppy
disk controller and floppy disk drives, commonly found on IBM-PC compatible
systems.
The driver supports the following floppy diskette formats by using particular partitions:
<sys/fdio.h>:
FDIOCGETFORMAT
struct fdformat_parmsFDIOCSETFORMAT
struct fdformat_parmsFDIOCFORMAT_TRACK
struct fdformat_cmdEINVAL, the track formatting parameters were out
of range for the medium. If it returns EIO, there
was a medium error while formatting the track.FDIOCSETOPTS
intFDOPT_NORETRYFDOPT_SILENTFDIOCGETOPTS
intA typical use of the formatting facilities would be to open the
device, call FDIOCGETFORMAT to fetch the current
format parameters, perhaps change a parameter or two, display the formatting
details to the user, and then call FDIOCSETFORMAT
followed by a series of calls to
FDIOCFORMAT_TRACK.
fdc formatting support appeared in
NetBSD 1.3.
