NAME

       dossrv, 9660srv, a:, b:, c:, eject - DOS and ISO9660 file systems

SYNOPSIS

       dossrv [ -v ] [ -s ] [ -f file ] [ service ]

       9660srv [ -v ] [ -s ] [ -f file ] [ service ]

       a:

       b:

       c:

       eject [ n ]

DESCRIPTION

       Dossrv  is a file server that interprets DOS file systems.  A single instance of dossrv can provide access to multiple DOS disks simultane-
       ously.

       Dossrv posts a file descriptor named service (default dos) in the /srv directory.  To access the DOS file system on  a  device,	use  mount
       with  the  spec	argument  (see bind(1)) the name of the file holding raw DOS file system, typically the disk.  If spec is undefined in the
       mount, dossrv will use file as the default name for the device holding the DOS system.

       Normally dossrv creates a pipe to act as the communications channel between itself and its clients.  The -s flag instructs  dossrv  to  use
       its  standard input and output instead.	The kernels use this if they are booting from a DOS disk.  This flag also prevents the creation of
       an explicit service file in /srv.

       The -v flag causes verbose output for debugging.

       The shell script a: contains

	      unmount /n/a: >[2] /dev/null
	      mount -c /srv/dos /n/a: /dev/fd0disk

       and is therefore a shorthand for mounting a floppy disk in drive A.  The scripts b: and c: are similar.

       9660srv is identical to dossrv in specification, except that it interprets ISO9660 CD-ROM file systems instead of DOS file systems.

       If the floppy drive has an ejection motor, eject will spit out the floppy from drive n, default 0.

EXAMPLE

       Mount a floppy disk with a DOS file system on it.

	      dossrv
	      a:
