+.Sh NAME
+.Nm fdc
+.Nd NEC 765 floppy disk controller driver
+.Sh SYNOPSIS
+.Cd "fdc0 at isa? port 0x3f0 irq 6 drq 2"
+.Cd "fdc* at acpi?"
+.Cd "fdc* at pnpbios? index ?"
+.Cd "fd* at fdc? drive ?"
+.Sh DESCRIPTION
+The
+.Nm
+driver provides support for the NEC 765 floppy disk controller and
+floppy disk drives, commonly found on IBM-PC compatible systems.
+.Pp
+The driver supports the following floppy diskette formats by using
+particular partitions:
+.Bl -tag -width xxxx -offset indent -compact
+.It 1.44MB 3.5-inch (b)
+.It "1.2MB " 5.25-inch (c)
+.It "360KB " 5.25-inch (1.2MB drive) (d)
+.It "360KB " 5.25-inch (IBM-PC drive) (e)
+.It "720KB " 3.5-inch (f)
+.It "720KB " 5.25-inch (g)
+.It "360KB " 3.5-inch (h)
+.El
+Partition
+.Ar a
+selects the default format for the attached floppy drive, as determined
+by the BIOS configuration for the diskette drive.
+.Sh FORMATTING
+The driver supports floppy disk formatting using the interfaces in
+.In sys/fdio.h :
+.Bl -tag -width FDIOCFORMAT_TRACK -compact
+.It Dv FDIOCGETFORMAT Fa struct fdformat_parms
+Fetch current formatting parameters.
+This gets the default parameters
+for the open device if no parameters have been set during the session.
+.It Dv FDIOCSETFORMAT Fa struct fdformat_parms
+Set formatting parameters.
+The driver saves this state and it persists while the device is open.
+.It Dv FDIOCFORMAT_TRACK Fa struct fdformat_cmd
+Format a track on the medium.
+If this call returns
+.Er EINVAL ,
+the track formatting parameters were out of range for the medium.
+If it returns
+.Er EIO ,
+there was a medium error while formatting the track.
+.It Dv FDIOCSETOPTS Fa int
+Set driver options which persist until the device is closed.
+The options should be the logical OR of the desired values below:
+.Bl -tag -width FDOPT_NORETRY -compact
+.It Dv FDOPT_NORETRY
+Do not retry operations on failure
+.It Dv FDOPT_SILENT
+Do not print error messages to the console
+.El
+.It Dv FDIOCGETOPTS Fa int
+Fetch drive options.
+.El
+.Pp
+A typical use of the formatting facilities would be to open the device,
+call
+.Dv FDIOCGETFORMAT
+to fetch the current format parameters, perhaps
+change a parameter or two, display the formatting details to the user,
+and then call
+.Dv FDIOCSETFORMAT
+followed by a series of calls to
+.Dv FDIOCFORMAT_TRACK .
+.Sh SEE ALSO
+.Xr fdformat 1 ,
+.Xr acpi 4 ,
+.Xr isa 4 ,

+.Nm kmem
+.Nd memory files
+.Sh DESCRIPTION
+The special file
+.Nm /dev/mem
+is an interface to the physical memory of the computer.
+Byte offsets in this file are interpreted as physical memory addresses.
+Reading and writing this file is equivalent to reading and writing
+memory itself.
+Only offsets within the bounds of
+.Nm /dev/mem
+are allowed.
+.Pp
+Kernel virtual memory is accessed through the interface
+.Nm /dev/kmem
+in the same manner as
+.Nm /dev/mem .
+Only kernel virtual addresses that are currently mapped to memory are allowed.
+.Pp
+On
+.Tn ISA
+the
+.Tn I/O
+memory space begins at physical address 0x000a0000
+and runs to 0x00100000.
+The
+per-process data
+size
+for the current process
+is
+.Dv UPAGES
+long, and ends at virtual
+address 0xfe000000.
