I.   OVERVIEW:::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::

   This README file pertains to the current release of the firmware flash
   file for the MarkNet N2501e and N2401e internal network adapters.

   Package file:
   Flash file name:  5_20_26.pml
   FLASH RELEASE     5.20.26
   Release date:     December 20, 2002


   1) The flash file extension, .pml, is used by the various utilities
      to distinguish between the various flash file types.  The file
      extension must not be changed.
   2) Due to the increased support for LDD profiles it will now be
      necessary to NVRAM reset an adapter if you are downgrading from
      this revision to an earlier firmware level.
   3) Note that pinging the adapter with large frames (over 1472 bytes)
      is not supported in this (and previous) firmware revision(s).  There
      are no problems with doing a 'regular' ping command.

II.  KEY FEATURES AND BENEFITS OF THE RELEASE:::::::::::::::::::::::::::::

   1) Improved paper jam handling on the OptraImage 725 scanner.

   2) Added the "No Fax Detected" status to replace "Voice Call" and
      incorrect fax polling calls.  (This MFP does not support fax polling.)

   3) Improved non-ECM fax receive.

   4) Corrected page count on fax logs for cancelled non-ECM received faxes.

   5) Improved fax reception from certain OKI fax machines.

   6) Sped up the print time for the last page of copies from the X443 ADF.

   7) Corrected a TCP/IP problem that could lead to corrupt scan to network
      (e-mail / ftp) images on specific network configurations.

   8) Changed the stratum level for NTP to 16.

   9) Addressed an NTP issue where changing the NTP server did not always
      take effect immediately.


   One of the following methods are required to update the MarkNet N2501e
   with this release of firmware flash:
   1) The flash file can be sent down to the adapter via TFTP with a 
      binary transfer.  In the following examples the flash file is
      located in the C:\inaflash\ directory.

   NT server example:

      C:\tftp -i PUT C:\inaflash\5_20_26.pml /dev/flash
      Transfer successful: 648434 bytes in 13 seconds, 19910 bytes/s

   OS/2 Server example:

      IBM TCP/IP for OS/2 - TFTP Client ver 14:02:01 on Oct 24 1995.
      tftp> bin
      tftp> put
      (file) c:\inaflash\5_20_26.pml /dev/flash
      Sent 648434 bytes in 10.8 seconds
