NAME

     pcata - PCMCIA ATA card device driver

SYNOPSIS

     pcata@socket#:a -u

     pcata@socket#:a -u,raw

DESCRIPTION

     The  PCMCIA ATA card device driver supports PCMCIA ATA  disk
     and flash cards that follow the following standards:

        o  PC card 2.01 compliance (MBR+fdisk table required  for
           all platforms).

        o  PC card ATA 2.01 compliance.

        o  PC card services 2.1 compliance.

     The driver supports standard PCMCIA ATA cards that contain a
     Card  Information  Structure  (CIS).  For  PCMCIA, nodes are
     created in /devices that include the socket  number  as  one
     component  of  the device name referred to by the node. How-
     ever, the names in /dev, /dev/dsk, and  /dev/rdsk follow the
     current conventions for ATA devices, which do not encode the
     socket number in any part of the name. For example, you  may
     have the following:

     ___________________________________________________________________________
    |        Platform        |                           |                     |

PRECONFIGURATION

     If a PC Card ATA device is recognized, the pcata  driver  is
     automatically loaded, IRQs allocated, devices nodes created,
     and special files created (if they do not already exist).

  Known Problems and Limitations
        o  vold does not support  pcata.  File  systems  must  be
           mounted manually.

        o  You need to umount the file system before removing the
           disk.

        o  The ufs file systems on removable media (PC Card  ATA)
           should  have  one of the onerror={panic, lock, umount}
           mount options set.

CONFIGURATION

     Configuration topics include initial installation and confi-
     guration,  identifying an unrecognized device, special files
     and hot-plugging.

  Initial Installation and Configuration
     1. Install the Solaris software.

     2. Boot the system.

     3. Insert the PC card ATA device.

  Identifying an Unrecognized Device
     If you insert a PC card ATA device and it is not  recognized
     (no special files created), use the prtconf command to iden-
     tify the problem.

     1. Run the prtconf -D command to see if your pcata  card  is
        recognized.  (A  recognized device will appear at the end
        of the prtconf output. For example:

     # prtconf -D
     .  .  .
     pcic, instance #0 (driver name: pcic)
         .  .  .
        disk, instance #0

     2. If pcata does not appear in the prtconf output, there  is
        a  problem with the PC card adapter configuration or with
        the hardware. Check to see whether the  problem  is  with
        the  card  or  the  adapter  by trying to use the card on
        another machine and by seeing if it  works  on  the  same
        machine using DOS.

  Special Files
     For PC card devices, nodes  are  created  in  /devices  that
     include  the socket number as one component of a device name
     that the node refers to. However, the  /prtc/dev  names  and
     the  names  in  /dev/dsk and /dev/rdsk do follow the current
     convention for ATA devices, which do not encode  the  socket
     number in any part of the name.

  Hot-Plugging
        o  If you want to remove the disk, you must  unmount  the
           file system.

        o  Use the mkfs_pcfs(1M) command to create  a  pcfs  file
           system:

     # mkfs -F pcfs /dev/rdsk/c#d#p0:d

        o  To mount a pcfs file system, type:

     # mount -F pcfs /dev/dsk/c#d#p0:c /mnt

        o  If you want to create a ufs file system, use the newfs
           command and type:

     # newfs /dev/rdsk/c#d#s#

        o  To mount a ufs file system, type:

     # mount -F ufs /dev/dsk/c#d#s# /mnt

        o  To create a Solaris partition, run the format  command
           and  go  to  the Partition menu. For more information,
           see the format(1M) man page.
