-.Sh DESCRIPTION
-.Nm
-is a file system type that enables direct access to files on FAT formatted disks
-from within the SunOS operating system.
-.Pp
-Once mounted,
-.Nm
-provides standard file operations and semantics.
-Using
-.Nm
-you can create, delete, read, and write files on a FAT formatted disk.
-You can also create and delete directories and list files in a directory.
-.Pp
-.Nm
-supports FAT12 (floppies) and FAT16 and FAT32 file systems.
-.Pp
-.Nm
-file systems can be force umounted using the
-.Fl -f
-argument to
-.Xr umount 1M .
-.Pp
-The
-.Nm
-file system contained on the block special file identified by
-.Fa spec
-is mounted on the directory identified by
-.Fa dir .
-.Fa spec
-and
-.Fa dir
-are pointers to pathnames.
-.Fa mflag
-specifies the
-.Fa mount
-options.
-The
-.Dv MS_DATA
-bit in
-.Fa mflag
-must be set.
-Mount options can be passed to
-.Nm
-using the optptr and optlen arguments.
-See
-.Xr mount_pcfs 1M
-for a list of mount options supported by
-.Nm
-.Pp
-Because FAT formatted media can record file timestamps between January 1st 1980
-and December 31st 2127, it's not possible to fully represent UNIX
-.Vt time_t
-in
-.Nm
-for 32 bit or 64 bit programs.
-In particular, if post-2038 timestamps are present on a FAT formatted medium and
-.Nm
-returns these, 32bit applications may unexpectedly fail with
-.Er EOVERFLOW
-errors.
-To prevent this, the default behaviour of
-.Nm
-has been modified to clamp
-post-2038 timestamps to the latest possible value for a 32bit
-.Vt time_t ,
-which is January 19th 2038, 03:14:06 UTC when setting and retrieving file
-timestamps.
-You can override this behavior using the
-.Ar noclamptime
-mount option, as described in
-.Xr mount_pcfs 1M .
-.Pp
-Timestamps on FAT formatted media are recorded in local time.
-If the recording and receiving systems use different timezones, the
-representation of timestamps shown on the two systems for the same medium might
-vary.
-To correct this,
-.Nm
-provides a timezone mount option to force interpretation
-of timestamps as read from a FAT formatted medium in a given timezone
-.Pq that of the recorder .
-By default, the local timezone of the receiver is used.
-See
-.Xr mount_pcfs 1M
-for details.
-.Pp
-The root directory of a FAT formatted medium has no timestamps and
-.Nm
-returns the time when the mount was done as timestamp for the root of the
-filesystem.
-.Pp
-The FAT filesystem doesn't support multiple links.
-As a result, the link count
-for all files and directories in
-.Nm
-is hard-coded as
-.Dq 1 .
-.Ss Mounting File Systems
-Use the following command to mount
-.Nm
-from diskette:
-.Bd -literal -offset indent
-mount -F pcfs device-special directory-name
-.Ed
-.Pp
-You can use:
-.Bd -literal -offset indent
-mount directory-name
-.Ed
-if the following line is in your
-.Pa /etc/vfstab
-file:
-.Bd -literal -offset indent
-device-special - directory-name pcfs - no rw
-.Ed
-.Pp
-Use the following command to mount
-.Nm
-from non-diskette media:
-.Bd -literal -offset indent
-mount -F pcfs device-special:logical-drive directory-name
-.Ed
-.Pp
-You can use:
-.Bd -literal -offset indent
-mount directory-name
-.Ed
-if the following line is in your
-.Pa /etc/vfstab
-file:
-.Bd -literal -offset indent
-device-special:logical_drive - directory-name pcfs - no rw
-.Ed
-.Pp
-.Ar device-special
-specifies the special block device file for the diskette
-.Pq Pa /dev/disketteN
-or the entire hard disk
-.Po
-Pa /dev/dsk/cNtNdNp0
-for a SCSI, SATA, NVME disk, and
-.Pa /dev/dsk/cNdNp0
-for IDE disks
-.Pc
-or the PCMCIA pseudo-floppy memory card
-.Pq Pa /dev/dsk/cNtNdNsN .
-.Pp
-.Ar logical-drive
-specifies either the DOS logical drive letter
-.Po
-.Sy c
-through
-.Sy z
-.Pc
-or a drive number
-.Pq 1 through 24 .
-Drive letter
-.Sy c
-is equivalent to drive number
-.Sy 1
-and represents the Primary DOS partition on the disk; drive letters
-.Sy d
-through
-.Sy z
-are equivalent to drive numbers
-.Sy 2
-through
-.Sy 24 ,
-and represent DOS drives within the Extended FAT partition.
-Note that
-.Ar device-special
-and
-.Ar logical-drive
-must be separated by a colon.
-.Pp
-.Ar directory-name
-specifies the location where the file system is mounted.
-.Pp
-For example, to mount the Primary DOS partition from a SCSI hard disk,
-use:
-.Bd -literal -offset indent
-mount -F pcfs /dev/dsk/cNtNdNp0:c /pcfs/c
-.Ed
-.Pp
-To mount the first logical drive in the Extended DOS partition from an IDE hard
-disk, use:
-.Bd -literal -offset indent
-mount -F pcfs /dev/dsk/cNdNp0:d /pcfs/d
-.Ed
-.Pp
-To mount a DOS diskette in the first floppy drive when volume management is not
-running use:
-.Bd -literal -offset indent
-mount -F pcfs /dev/diskette /pcfs/a
-.Ed
-.Pp
-If Volume Management is running, run
-.Xr volcheck 1
-to automatically mount the floppy and some removable disks.
-.Pp
-To mount a PCMCIA pseudo-floppy memory card, with Volume Management not running
-.Pq or not managing the PCMCIA media ,
-use:
-.Bd -literal -offset indent
-mount -F pcfs /dev/dsk/cNtNdNsN /pcfs
-.Ed
-.Ss "Conventions"
-Files and directories created through
-.Nm
-must comply with either the FAT short file name convention or the long file name
-convention introduced with Windows 95.
-The FAT short file name convention is of the form
-.Pa filename[.ext] ,
-where
-.Em filename
-generally consists of from one to eight upper-case characters, while the
-optional
-.Em ext
-consists of from one to three upper-case characters.
-.Pp
-The long file name convention is much closer to illumos file names.
-A long file name can consist of any characters valid in a short file name,
-lowercase letters, non-leading spaces, the characters
-.Sy +,;=[] ,
-any number of periods, and can be up to 255 characters long.
-Long file names have an associated short file name for systems that do not
-support long file names.
-The short file name is not visible if the system recognizes long file names.
-.Nm
-generates a unique short name automatically when creating a long file name.
-.Pp
-Given a long file name such as
-.Pa This is a really long filename.TXT ,
-the short file name will generally be of the form
-.Pa THISIS~N\&.TXT ,
-where
-.Em N
-is a number.
-The long file name will probably get the short name
-.Pa THISIS~1.TXT ,
-or
-.Pa THISIS~2.TXT
-if
-.Pa THISIS~1.TXT
-already exits
-.Po or
-.Pa THISIS~3.TXT
-if both exist, and so forth
-.Pc .
-If you use
-.Nm
-file systems on systems that do not support long file names, you may want to
-continue following the short file name conventions.
-See
-.Sx EXAMPLES .
-.Pp
-When creating a file name,
-.Nm
-creates a short file name if it fits the FAT short file name format, otherwise
-it creates a long file name.
-This is because long file names take more directory space.
-Because the root directory of a
-.Nm
-file system is fixed size, long file names in the root directory should be
-avoided if possible.
-.Pp
-When displaying file names,
-.Nm
-shows them exactly as they are on the media.
-This means that short names are displayed as uppercase and long file names
-retain their case.
-Earlier versions of
-.Nm
-folded all names to lowercase, which can be forced with the
-.Dv PCFS_MNT_FOLDCASE
-mount option.
-All file name searches within
-.Nm ,
-however, are treated as if they were uppercase, so
-.Pa readme.txt
-and
-.Pa ReAdMe.TxT
-refer to the same file.
-.Pp
-To format a diskette or a PCMCIA pseudo-floppy memory card in FAT format in the
-SunOS system, use either the
-.Xr fdformat 1
-.Fl -d
-or the DOS
-.Sy FORMAT
-command.
-.Ss Boot Partitions
-On x86 systems, hard drives may contain an fdisk partition reserved for the boot
-utilities.
-The most common case is the EFI system partition.
-These partitions are special instances of
-.Nm .
-You can mount an x86 boot partition with the command:
-.Bd -literal -offset indent
-mount -F pcfs device-special:boot directory-name
-.Ed
-or you can use:
-.Bd -literal -offset indent
-mount directory-name
-.Ed
-if the following line is in your
-.Pa /etc/vfstab
-file:
-.Bd -literal -offset indent
-device-special:boot - directory-name pcfs - no rw
-.Ed
-.Pp
-.Ar device-special
-specifies the special block device file for the entire hard disk
-.Pq Pa /dev/dsk/cNtNdNp0
-.Pp
-.Ar directory-name
-specifies the location where the file system is mounted.
-.Pp
-All files on a boot partition are owned by super-user.
-Only the super-user may create, delete, or modify files on a boot partition.
-.Sh ENVIRONMENT
-See
-.Xr environ 5
-for descriptions of the following environment variables
-for the current locale setting:
-.Ev LANG ,
-.Ev LC_ALL ,
-.Ev LC_CTYPE ,
-and
-.Ev LC_COLLATE .

-.Sh EXAMPLES
-.Sy Example 1
-Sample Displays of File Names
-.Pp
-If you copy a file
-.Pa financial.data
-from a UNIX file system to
-.Nm ,
-it displays as
-.Pa financial.data
-in
-.Nm
-but may show up as
-.Pa FINANC~1.DAT
-in systems that do not support long file names.
-.Pp
-The following are legal long file names.
-They are also illegal short file names:
-.Bl -item -offset indent
-.It
-.Pa test.sh.orig
-.It
-.Pa data+
-.El
-.Pp
-Other systems that do not support long file names may see:
-.Bl -item -offset indent
-.It
-.Pa TESTSH~1.ORI
-.It
-.Pa DATA~1
-.It
-.Pa LOGIN~1
-.El
-The short file name is generated from the initial characters of the long file
-name, so differentiate names in the first few characters.
-For example, these names:
-.Bl -item -offset indent
-.It
-.Pa WorkReport.January.Data
-.It
-.Pa WorkReport.February.Data
-.It
-.Pa WorkReport.March.Data
-.El
-result in these short names, which are not distinguishable:
-.Bl -item -offset indent
-.It
-.Pa WORKRE~1.DAT
-.It
-.Pa WORKRE~2.DAT
-.It
-.Pa WORKRE~2.DAT
-.It
-.Pa WORKRE~2.DAT
-.It
-.Pa WORKRE~13.DAT
-.El
-.Pp
-These names, however:
-.Bl -item -offset indent
-.It
-.Pa January.WorkReport.Data
-.It
-.Pa February.WorkReport.Data
-.It
-.Pa March.WorkReport.Data
-.El
-result in the more descriptive short names:
-.Bl -item -offset indent
-.It
-.Pa JANUAR~1.DAT
-.It
-.Pa FEBRUA~1.DAT
-.It
-.Pa MARCHW~1.DAT

-.Sh WARNINGS
-Do not physically eject a FAT floppy while the device is mounted as
-.Nm
-If Volume Management is managing a device, use the
-.Xr eject 1
-command before physically removing media.
-.Pp
-When mounting
-.Nm
-on a hard disk, make sure the first block on that device contains a valid fdisk
-partition table.
-.Pp
-Because
-.Nm
-has no provision for handling owner-IDs or group-IDs on files,
-.Xr chown 1
-or
-.Xr chgrp 1
-may generate various errors.
-This is a limitation of
-.Nm
-but it should not cause problems other than error messages.
-.Sh NOTES
-Only the following characters are allowed in
-.Nm
-short file names and extensions:
-.Bl -item -offset indent
-.It
-0-9
-.It
-A-Z
-.It
-$#&@!%()-{}<>`_^~|'
-.It
-.El
-illumos and FAT use different character sets and have different
-requirements for the text file format.
-Use the
-.Xr dos2unix 1
-and
-.Xr unix2dos 1
-commands to convert files between them.
-.Pp
-.Nm
-offers a convenient transportation vehicle for files between multiple systems.
-Because the FAT disk format was designed for use under DOS, it does not operate
-efficiently under illumos and should not be used as the format for a regular
-local storage.
-Instead, use ZFS for local storage within an illumos system.
-.Pp
-Although long file names can contain spaces
-(just as in UNIX file names) ,
-some utilities may be confused by them.
-.Pp
-When
-.Nm
-encounters long file names with non-ASCII characters, it converts such long file
-names in Unicode scalar values into UTF-8 encoded filenames so that they are
-legible and usable with any of illumos UTF-8 locales.
-In the same context, when new file names with non-ASCII characters are created,
-.Nm
-expects that such file names are in UTF-8.
-This feature increases the interoperability of
-.Nm
-on illumos with other operating
-systems.
-.Sh BUGS
-.Nm
-should handle the disk change condition in the same way that DOS does, so you do
-not need to unmount the file system to change floppies.
