    and is currently supported on the following Linux distributions:

        * RedHat 5.2
        * RedHat 6.x
	* RedHat 7.x
        * Debian Linux 2.1

Classicboard (Corsair) 8 PCI	       8

3. ENHANCEMENTS

 -- Converted the driver to install via Source RPM 
 -- Removed doinst.sh/predelete.sh, due to SRPM installation
 -- Extensively changed directory layout, due to SRPM installation
 -- rc.cpci now supports load/unload arguments
 -- Move driver from BETA to RELEASE status
 -- Changed version number to 1.0.0-1

 cpci.c
 ------
 -- Removed register_serial() and unregister_serial() functions - and their
    associated symbol exports, as A) we don't need them (The code in
    question is left over from the native linux serial driver, from which
    this driver was based on) and B) they interfere with compilation, if the
    user isn't using CONFIG_MODVERSIONS
 -- Changed version to 1.0.0

 all
 ---
 -- a general scripts directory was added.
 -- 'kwhich' script added. (This is the same kwhich script that exists
    in the 2.2.18 scripts directory.)  It determines whether or not we
    should be compiling with kgcc. (This makes redhat 7.0 work, where
    we would've generated buggy code - with the stock compiler.)
 
4. BUGFIXES
N/A


5. KNOWN LIMITATIONS
 
 -- In Redhat 7.0, you MUST install the kgcc RPM package before you
    attempt to install this driver.  The default compiler (gcc 2.96) is
    known to generate buggy code. If the kgcc package is not installed
    before you install this driver package the driver will be compiled
    with the default compiler.  Digi will NOT support this configuration,
    as it may operate unreliably, or could even crash your system.
 -- Since the rated throughput value of the Linux tty/FLIP buffer code is
    25k per second, 460kbps users CAN and WILL see speed bottlenecks.  This
    is not a digi bug, but rather - is a well documented problem with the
    tty management code within Linux itself.


6. HISTORY

  Version 1.0.0b1 - March 27, 2000
  --------------------------------

  cpci
  ----
  -- Initial Release
  -- Supports both Classicboard 4/8
  -- Set initial version to 1.0.0Beta1

  rpm installer/doinst.sh/predelete.sh
  ------------------------------------
  -- Compiles and installs the driver at rpm install time
  -- doinst.sh/predelete.sh are scripts that installs the driver on rpm -i, 
     as well as deleting the driver on rpm -e
  -- doinst.sh/predelete.sh - version 1.0

  createdevs
  ----------
  -- Small utility that creates devices using a particular major number
  -- Version 1.0

  cpcicreate.sh
  -------------
  -- Since we're doing dynamic device allocation with this driver, this
     script awks/greps out the major number of the currently running 
     driver, and creates devices on the fly, using that major number.
  -- Version 1.0

  rc.cpci
  -------
  -- This file can be called at boot time, thus initializing the cpci
     driver (and the board), as well as using cpcicreate.sh/createdevs
     to build the proper tty's.
  -- Version 1.0

  failures.txt
  ------------
  -- Document that describes common failures on installation, and their
     respective fixes.
