***********************
* VERSION INFORMATION *
***********************

This is release 1.01a of the Digital UNIX driver for the ATMworks 351 
ATM/PCI NIC.  To determine the version of the driver currently 
installed on your system, perform the following command:

# setld -i | grep LPADRV  

If no output is displayed, than the driver is not installed on the system.
Typically you would see a line of text similiar to this:
   
   LPADRV100            installed  ATM 155 Mbit device driver

This indicates that version 1.00 of the driver is installed.

Refer to the file readme.txt for how to get the latest revision of the 
driver.

******************************
* CONFIGURATION RESTRICTIONS *
******************************

Follow the guideline suggestions in the readme.txt file.

**************
* KNOWN BUGS *
**************

1) FLOWmaster was not qualified on AlphaServers, therefore it is
   not supported and should NOT be enabled.

2) False Generation of PCI Parity Errors for Revision C01 and
   earlier cards (later revisions of the cards have software 
   workarounds).

   In extremely rare circumstances, a false parity may occur while 
   the driver is reading a CSR on the NIC.  If PCI parity checking
   is enabled on the PCI bus, then the machine will halt.  

   If a crash occurs, grep the file /var/adm/crash-data for the
   string "lpa_int_handler".  If the line "read_io_port" immediately
   precedes it, then the ATMworks 351 generated a false parity error.
 
******************************
* BUG FIXES AND NEW FEATURES *
******************************

- Added a parity workaround that prevents parity errors for cards 
  labeled D01 and above.

- Fixed a couple of timing windows that may have caused a crash.

- Improved transmit lockup workaround.

- Adding more debug information that is accessed via the 
  Digital UNIX "sysconfig -q lpa" command.
