NAME

     pxupgrade - upgrade firmware in Plextor CD/DVD writers


SYNOPSIS

     pxupgrade [ options ] [ dev=device ] firmware_file


DESCRIPTION

     Pxupgrade is used to update the firmware in Plextor  CD  and
     DVD writers as well as in the PX-40 CD-ROM drive.

     See OPTIONS and EXAMPLES  section  to  lean  about  possible
     usage.

  Device naming
     Most users do not need to care about device naming  at  all,
     as  pxupgrade  implements  auto target support and automagi-
     cally finds Plextor drives.

     The device  refers  to  scsibus/target/lun  of  the  CD/DVD-
     Recorder.  Communication on SunOS is done with the SCSI gen-
     eral driver scg. Other operating systems are using a library
     simulation  of  this  driver.   Possible  syntax  is:   dev=
     scsibus,target,lun or dev= target,lun.  In the latter  case,
     the  CD/DVD-Recorder has to be connected to the default SCSI
     bus of the machine.  Scsibus, target  and  lun  are  integer
     numbers.  Some operating systems or SCSI transport implemen-
     tations may require to specify a filename in  addition.   In
     this  case  the  correct  syntax  for  the  device is:  dev=
     devicename:scsibus,target,  or  dev=  devicename:target,lun.
     If  the  name  of the device node that has been specified on
     such a system refers to exactly one SCSI device, a shorthand
     in  the  form dev= devicename:@ or dev= devicename:@,lun may
     be used instead of dev= devicename:scsibus,target,

     To access remote SCSI devices, you need to prepend the  SCSI
     device  name by a remote device indicator. The remote device
     indicator is either REMOTE:user@host:  or  REMOTE:host:
     A valid remote SCSI device name may  be:   REMOTE:user@host:
     to  allow remote SCSI bus scanning or REMOTE:user@host:1,0,0
     to access the SCSI device at host connected to  SCSI  bus  #
     1,target 0 lun 0.

     Pxupgrade is completely based on SCSI commands but  this  is
     no problem as all CD/DVD writers ever made use SCSI commands
     for the communication.  Even  ATAPI  drives  are  just  SCSI
     drives  that inherently use the ATA packet interface as SCSI
     command transport layer build into the IDE (ATA)  transport.
     You  may need to specify an alternate transport layer on the
     command   line  if  your  OS  does  not  implement  a  fully
     integrated kernel driver subsystem that allows to access any

     drive using SCSI commands via a single  unique  user  inter-
     face.

     To access SCSI devices via alternate transport  layers,  you
     need  to  prepend  the SCSI device name by a transport layer
     indicator.  The transport layer indicator may  be  something
     like USCSI: or ATAPI:.  To get a list of supported transport
     layers for your platform, use dev= HELP:

     To make pxupgrade portable to all UNIX platforms, the syntax
     dev=  devicename:scsibus,target, is preferred as it hides OS
     specific knowledge about device  names  from  the  user.   A
     specific  OS  may not necessarily support a way to specify a
     real   device   file   name   nor   a   way    to    specify
     scsibus,target,lun.

     Scsibus 0 is the default SCSI bus on the machine. Watch  the
     boot   messages   for   more   information   or   look  into
     /var/adm/messages for more information about the SCSI confi-
     guration  of  your  machine.  If you have problems to figure
     out what values for scsibus,target,lun should be  used,  try
     the -scanbus option of cdrecord described below.


OPTIONS

     -all Upgrade all drives which  may  be  upgraded  using  the
          specified upgrade file.

     dev=target
          Sets the SCSI target for the CD/DVD-Recorder, see notes
          above.  A typical device specification is dev=6,0 .  If
          a filename must be provided together with the numerical
          target  specification,  the  filename is implementation
          specific.  The correct filename in  this  case  can  be
          found  in  the  system  specific  manuals of the target
          operating system.  On a FreeBSD system without CAM sup-
          port,   you  need  to  use  the  control  device  (e.g.
          /dev/rcd0.ctl).  A correct device specification in this
          case may be dev=/dev/rcd0.ctl:@ .

          On Linux, drives connected to a parallel  port  adapter
          are  mapped  to  a virtual SCSI bus. Different adapters
          are mapped to different targets on  this  virtual  SCSI
          bus.

     -l   List all Plextor drives  with  their  current  firmware
          version.   This  works  only if the current OS platform
          allows SCSI bus scanning for user programs.

Schily's USER COMMANDS                               PXUPGRADE(1)

     -help
          Prints a short summary of  the  pxupgrade  options  and
          exists.

     -version
          Prints the pxupgrade version number string and exists.


EXAMPLES

     Use

        pxupgrade -all    r412c106.bin

     to upgrade all Plextor PX-W412  drives  that  may  be  found
     using the SCSI scan bus function of the OS.

     Use

        pxupgrade dev=3,0 r412c106.bin

     to upgrade the Plextor PX-W412 drive at target 3 lun 0.

     Use

        pxupgrade -l

     to list all Plextor drives with their  firmware  if  the  OS
     supports SCSU bus scanning.

     Use

       pxupgrade dev=USCSI -l

     to list all Plextor drives with  their  firmware  using  the
     alternate SCSU transport method USCSI.

     Use

        pxupgrade dev=IOCompactDiscServices -l

     On MacOS X to list the first CD-ROM drive in the system.


NOTES

     If the update is done with an ATAPI drive and DMA is active,
     it  is  likely  that  the drive will hang after the firmware
     update as this operation puts the drive in PIO mode.
