     Plextor Firmware Update program        
*****************************************************************************

  Usage
  -----

  Type PXUpdate at the command prompt, followed by the filename and/or
  an option code.

  Command line options
  --------------------

   -l		displays a list of installed Plextor drives
   -id:x        x=SCSI ID (default=-1)
   -ha:x        x=hostadapter (default=0)
   dev=scsidev	specify a SCSI device (see cdrecord man page for details)
   -all		upgrade all upgradable Plextor drives

   The -ha and -id options may not work on all operating systems.
   The preferred way is to use the dev= option. This is the OS independent
   and portable SCSI device specifier.

   On Operating systems that do not support SCSI bus scanning, you need to
   use the dev= option.

   If -id or dev= is missing the drive(s) which will be used for the upgrade will be 
   determined by the specified upgrade file.
   If -id, dev= and -all are missing, the program will ask for each drive if 
   you want to upgrade them.


   Examples
   --------

   PXUpdate -l
   Display a list of all installed Plextor drives

   PXUpdate 40ts101.bin
   After scanning the file to see for which drive it is intended, the program
   will ask for each drive if you want to upgrade them.
   You can select y (yes), n (no) or a (all).   

   PXUpdate r412c106.bin -all
   Updates all PlexWriters in program mode with firmware V1.06.

   V1.03. The file r820t103.bin must be located in /tmp
