pcfs(7FS) File Systems SunOS 5.5
NAME pcfs, PCFS − DOS formatted file system
DESCRIPTION PCFS is a file system type that allows users direct access to files on DOS formatted disks
from within the SunOS operating system. Once mounted, a PCFS file system provides
standard SunOS file operations and semantics. That is, users can create, delete, read, and
write files on anDOS formatted disk. They can also create and delete directories and list
files in a directory.
Mounting File
Systems
PCFS file systems are mounted from diskette with the command:
mount −F pcfs device-special directory-name
or you can use:
mount directory-name
if the following line is in your /etc/vfstab file:
device-special − directory-name pcfs − no rw
x86: PCFS file systems are mounted from the hard disk with the command:
mount −F pcfs device-special:logical-drivedirectory-name
or you can use:
mount directory-name
if the following line is in your /etc/vfstab file:
device-special:logical_drive − directory-name pcfs − no rw
device-special specifies the special block device file for the diskette (/dev/disketteN) or the
entire hard disk (/dev/dsk/cNtNdNp0) or the PCMCIA pseudo-floppy memory card
(/dev/dsk/cNtNdNsN).
On x86 systems, logical-drive specifies either the DOS logical drive letter (c through z) or a
drive number (1 through 24). Drive letter c is equivalent to drive number 1 and
represents the Primary DOS partition on the disk; drive letters d through z are equivalent
to drive numbers 2 through 24, and represent DOS logical drives within the Extended
DOS partition. Note that device-special and logical-drive must be separated by a colon.
directory-name specifies the location where the file system is mounted.
For example, on x86, to mount the Primary DOS partition from a hard disk, use:
mount −F pcfs /dev/dsk/cNtNdNp0:c /pcfs/c
On x86, to mount the first logical drive in the Extended DOS partition from the hard disk,
use:
mount −F pcfs /dev/dsk/cNtNdNp0:d /pcfs/d
To mount a DOS diskette in the first floppy drive, use:
mount −F pcfs /dev/diskette /pcfs/a
