    PROBLEMS ADDRESSED IN ALPLAN06_062 KIT
    
    
         o  The system can crash with a "NETDLLERR, DECnet  Datalink  Layer
            detected a fatal error" bugcheck.
    
            Crash Information Summary:
    
            Bugcheck Type:     NETDLLERR, DECnet Datalink Layer detected
                                a fatal error

         o  If the LANCP.EXE image from ECO Kit ALPLAN05_062  was  used  to
            convert  or  add information to the device database, the device
            record  would  be  stored  with  the  wrong  database  version.
            Further  attempts  to  access or modify the device record would
            fail with a %LANCP-E-CONVERT error.
    
             Images Affected:[SYS$LDR]LANCP.EXE
         		   	 [SYS$LDR]LANACP.EXE
    
    
         o  When LSB$L_FX_CMDCNT is not reset, the user sees a rapid number
            of  errorlog  entries with firmware errors on a DEMFA.  This is
            followed by a loss of network connectivity.
    
             Images Affected:[SYS$LDR]SYS$FXDRIVER.EXE
    
    
    
         o  Duplicate characters are echoed back from  the  remote  console
            session of a terminal server, when using LANCP to establish the
            connection.
    
             Images Affected:[SYSEXE]LANCP.EXE
    
    
    
         o  The following corruption in a LAN packet causes an Alpha system
            to  crash with "INVEXCEPTN, Exception while above ASTDEL".  The
            PC related to the crash is:
    
              SYS$LAN_CSMACD_NPRO+05F80:  LDL  R26,#X0238(R5)
    
    
            The corrupted packet looks like this (for  formatting  purposes
            the following lines have been truncated):

         o  System crash when attempting to use a LAN UCB after it has been
            deassigned.
    
            Bugcheck Type:     INVEXCEPTN, Exception while above ASTDEL
            Current Image:
            Failing PC:        FFFFFFFF 802BBF50
            Failing PS:        20000000 00000804
            Module:            SYS$FRDRIVER
            Offset:            00011F50

         o  With a DE435 style integrated network adapter, it can take  too
            long  for  an application to know that a link has failed.  This
            will delay failover to another adapter.  The adapter should  be
            able to detect as soon as possible that a link has failed."
    
             Images Affected:[SYS$LDR]SYS$EWDRIVER.EXE
    
    
    
         o  Corruption of 1 byte (the very last byte is aligned just  after
            an  Alpha  page-boundary  -  8k)  during a write to MSCP served
            disk.
    
            A user would see  random  data  corruptions.   The  corruptions
            would  show up after a write operation to a file when the write
            operation started from another  node  over  the  network.   The
            written file would have 1-4 bytes corrupted.
            This is caused by  the  end  of  a  receive  operation  on  the
            EXDRIVER, crossing over a 8k page boundary.
    
             Images Affected:[SYS$LDR]SYS$EXDRIVER.EXE
    
    
    
         o  When a PEDRIVER transmit buffer is located in  memory  above  2
            gigabytes,  which  would be the user data portion of the buffer
            described by an  SCS  named  buffer,  and  the  length  of  the
            transmit  buffer  MOD  512 bytes is either 0x1E0 or 0, the last
            byte of the buffer is corrupted.
    
            The length of the buffer  is  calculated  as:   length  of  the
            PEDRIVER  header  +  user data + packet header + DEMFA transmit
            header.  This implies a user data buffer length of 390  or  422
            bytes  and  buffer lengths which are longer by multiples of 512
            bytes
    
             Images Affected:[SYS$LDR]SYS$FXDRIVER.EXE
    
    
    
         o  A sensemode $QIO to a Ethernet LAN driver  will  return,  send,
            and receive failures as a word-long bitmap representing various
            failure types followed by a 16-bit  total  count  of  failures.
            LANCP  fails  to take account of the bitmap and simply displays
            the bitmap and  count  as  a  single  longword  integer.   This
            results  in  grossly  over-inflated send and/or receive failure
            counts.
    
             Images Affected:[SYSEXE]LANCP.EXE
    
    
    
         o  During  a  self-test  restart,  a  system  can  crash  with  an
            INVEXCEPTN  error  when  the user issues a UCX$SHUTDOWN command
            after the FXDRIVER has logged a failure controller error.   The
            self-test  reset fails with a local store parity error (SPE) or
            a watch dog timeout  (WDT)  in  the  XPST  Control  and  Status
            Register (CSR).
    
            Bugcheck Type:     INVEXCEPTN, Exception while above ASTDEL
            Current Image:
            Failing PC:        FFFFFFFF 803977C0
            Failing PS:        30000000 00000804
            Module:            SYS$FXDRIVER

             Images Affected:[SYS$LDR]SYS$FXDRIVER.EXE
    
    
    
         o  LANCP  does  not  display  settings  in  the  permanent  device
            database  that  had  been  set  using  the  LANCP DEFINE DEVICE
            command.
    
             Images Affected:[SYSEXE]LANCP.EXE
    
    
    
         o  The 64-bit counters suppport in V7.1-2 was backported to V6.2R.
            This changes the LANCP SHOW DEV/COUNTERS command so it requests
            64-bit counters from the LAN driver and displays appropriately.
            The  LAN  common  routines was modified to recognize the 64-bit
            qualifer on the  'read  counters'  request  and  return  64-bit
            counters  if  requested,  rather  than  the  original NCP-style
            32-bit counters.
    
             Images Affected:[SYSEXE]LANCP.EXE
    			 [SYSEXE]LANACP.EXE
    
    
         o
    
             o  The user will see oversize (Giant)  packets  being  counted
                and  dropped  on  network  switch ports.  Applications will
                timeout waiting for these packets.
    
             o  DMA errors can  occur  when  a  multisegment  transmit  and
                second  page  happens  to  be  physical page 0X20000, which
                crosses the boundary where mapping registers are needed.
    
             o  The user would have delays before a received  packet  would
                be processed, even though the packet was in the adapter.
    
             o  Device driver will cause INCNSTATE crashes during boot.
    
             Images Affected:[SYS$LDR]SYS$EWDRIVER_DE500BA.EXE
    
    
    
    Problems addressed in the ALPLAN05_062 kit:
    
      o  Most of the DECnet OSI  Network  Management  problems  included
         incorrect  data  being  returned,  hangs  on  NCL commands, and
         crashes when incorrect commands were issued.
    
      o  Many structure entities are displaying wrong  values  and  some
         NCL commands in DECnet/PLUS cause systems to crash.
    
      o  Add support for the DE500-BA adapter and the  Gigabit  Ethernet
         adapter.
    
      o  For  heavy  Fast  Ethernet  devices,  user  buffer  unavailable
         counters and re-transmits increased, slowing performance.
    
      o  Changes were made so  that  100  mbs  devices  will  have  more
         receive buffers available to the users (VCI or QIO).
    
      o  When a cable is pulled or a link  fails,  due  to  an  upstream
         device   losing   power,   the   autosense  fails  to  stay  at
         twisted-pair if the console is set to twisted-pair mode.
    
      o  BMAP/BNOMAP DMA error and oversize packet
    
         1.  A potential  DMA  error  can  occur  from  a  multi-segment
             transmit  with  a  buffer  that  crossed  the page boundary
             between unmapped and mapped physical memory.
    
         2.  A second problem  was  that  oversize  packets  were  being
             issued by the EWDRIVER devices.
    
      o  Pool   consumption   occurred   while   starting/stopping    an
         application  interface to a LAN driver.  After 100 start/stops,
         pool was consumed.  The problem only occurs when using  Network
         Management.  i.e.  NET$CSMACD, NET$FDDI, etc.
    
      o  Most customers are seeing the SS$_BADPARAM message when  trying
         to access MOP clients on the network.
    
      o  When  using  DE500  adapters,  the  system  unavailable  buffer
         counter  was  incremented  up  to  the  thousands,  along  with
         broadcast storms occurring.
    
      o  Numerous fixes for Token Ring on PCI adapters were done.
    
      o  Since a new version of the 3COM 3C589 PCMCIA Ethernet card  was
         released, the driver stopped working.  The new card did not fit
         the original timing parameters.  A C589 Ethernet card,  rev  D,
         reset timeout fix was needed.
    
      o  When a Satellite is booted over the DE425 and a system shutdown
         is  requested, the system will hang on the way down waiting for
         access to the system disk.  When the  runtime  driver  for  the
         DE425  shuts  down,  it writes CSR13 with the value for twisted
         pair, BNC or AUI to be used by the execlet bootdriver.
    
      o  Fatal device errors occurred due to transmit  timeouts  on  the
         DE205 when the 10baseT link is lost.
    
    
    Problems addressed in the ALPLAN04_062 kit:
    
      o  This TIMA kit provides the necessary files to support the
         DE500-AA Fast EtherWORKS PCI 10/100 adapter under the OpenVMS
         V6.2 Operating System and the associated V6.2 Hardware
         releases which includes; V6.2-1H1, V6.2-1H2, and V6.2-1H3.
         This allows OpenVMS V6.2 users to take advantage of the newest
         generation Fast Ethernet adapter from Digital Equipment
         Corporation without requiring a total Operating System
         upgrade.
    
         The DE500-AA supersedes the DE500-XA which is currently
         supported by OpenVMS V6.2.  Please Note:  OpenVMS V7.1 also
         includes support for the DE500-AA, and that the DE500-XA  will
         be retired by the end of March, 1997.  (Please refer to the
         ALPHA qualified options list to confirm support for your
         particular CPU.)
    
         The combination of this TIMA kit and the DE500-AA provides a
         form, fit, and functionally equivalent PCI to Fast Ethernet
         adapter to the DE500-XA on OpenVMS V6.2 host CPUs.  In
         addition, the DE500-AA adapter implements industry standard
         auto-negotiation for 10 or 100 Mbps and for half or full
         duplex, and includes a socket for optional ROM support.  Both
         the DE500-XA and the DE500-AA utilize a single RJ45 connector
         for connection to either a 10 or 100 Mbps Ethernet network.
    
         These adapters support full duplex Ethernet communication when
         connected to a cooperating full duplex-compatible device.
         Ensure that the connected device supports full duplex mode
         before forcing this feature, or serious network problems can
         result.  If auto-negotiate mode is used, this is not a
         concern, as the hardware will determine the duplex capability
         of the connected device.
    
         This kit also contains runtime images provided by previous
         OpenVMS V6.2 LAN kits.
    
           DE500-AA Runtime Device Driver (SYS$EWDRIVER.EXE)
    
             This driver adds support for the DE500-AA and continues to
             support the PCI Ethernet adapters that were previously
             supported by OpenVMS V6.2.  This includes the DE500-XA,
             DE450, and the DE435.  All these devices show up under
             the Operating System as EWx0, where x is the controller
             letter (e.g., A, B, C).
    
              A new feature of this driver is the use of a console
              environment variable to select the proper media
              connection for all EW devices.  For each EW device
              recognized by the console there is a console environment
              variable called EWx0_MODE.  The console environment
              variable is set with the command:
    
                >>> SET EWx0_MODE media_selection
    
              Where x is the controller letter (e.g.,  A, B, C) and
              media_selection is one of the following:
    
                Twisted-Pair
                Full Duplex, Twisted-Pair
                AUI
                BNC
                Fast
                FastFD (Full Duplex)
                Auto-Negotiate
    
              If a console environment variable has been set with an
              unsupported media type for the corresponding device then
              the driver will attempt to autosense or auto negotiate the
              media type.
    
              Note that an OpenVMS Alpha system console may assign a
              controller letter to an adapter differently than OpenVMS
              VAX.  It is recommended that the user issue a SHOW
              CONFIGURATION command at the console to determine the
              correct letter designation for each adapter.  In the
              case of different controller letter assignments, the
              letter designation in messages broadcast to the console
              by the driver may not agree with the console setting.
    
              This runtime device driver supports twisted pair media at
              speeds of 10 and 100 mbits/sec, full or half duplex, for the
              DE500-XA and DE500-AA.  A new feature of this driver, when
              used with the DE500-AA, is support for auto negotiation as
              proposed in the IEEE 802.3 standard.
    
              Auto negotiation provides a method to detect the
              operational characteristics supported by the device
              at the other end of the link, negotiate common abilities,
              and configure the link accordingly.  Auto negotiation
              always selects the highest common operating mode possible
              between the two link partners.  For the DE500-AA, the
              highest operating mode is 100 mbit/sec full duplex unless
              programmed to advertise a lesser mode.
    
              Auto negotiation is enabled, or disabled, by setting a console
              environment variable as described above.  To enable auto
              negotiation, set the console environment variable with the
              following command at the console:
    
                >>> SET EWx0_MODE AUTO-NEGOTIATE
    
              If auto negotiation is enabled, the other end of the link must
              also have auto negotiation enabled or the driver will not be
              able to negotiate an operating mode.  With auto negotiation
              enabled on both link partners, the OpenVMS driver can also
              dynamically detect changes in the link and renegotiate a new
              operating mode.  For this event the driver will broadcast
              messages to the operator console as shown in this example for
              EWB0:
    
                %EWB0, Auto Negotiation detected link down
    
                %EWB0, Fast(100baseT) Ethernet connection selected
    
              To disable auto negotiation using the console environment
              variable, the operating mode has to be explicitly selected.
              This example shows how to disable auto negotiation and
              enable the DE500-AA to operate at 100 mbits/sec full duplex:
    
                >>> SET EWx0_MODE FASTFD
    
              Restrictions
    
                The system firmware must be at a revision level that
                supports the DE500-AA.  The Alpha Firmware CD V3.8
                has the required support for each applicable system
                type.
    
      o  A fix to cure a minor memory leak exposed a more severe
         problem, double deallocation of pool, resulting generally
         in a system crash.  This kit removes the memory leak fix.
         Both problems will be corrected in a future release of
         OpenVMS.
    
    
    Problems addressed in the ALPLAN03_062 kit:
    
    Note:  According to OpenVMS Engineering, the fixes described below
           are included in the OpenVMS Alpha V7.1 software release.
    
          o  If the FDDI adapter (DEFTA, DEFPA, or DEFEA)  suffers  a  fatal
             error  requiring  the  driver to reset and restart the adapter,
             transmit workaround buffers may be lost resulting in  cessation
             of transmits which appears to be a hung system.
    
             This problem is corrected in OpenVMS Alpha V7.0
    
          o  For AlphaServer 1000-4/200 systems, on adapter reset, the DEFPA
             requires   an  additional  CSR  write  to  turn  off  PFI  chip
             interrupts  (as  compared  to  the   EISA,   Turbochannel   and
             Futurebus+  versions  of this adapter).  This was being done on
             reset but not in the adapter  shutdown  routine  called  during
             system shutdown.  The system would hang during shutdown, due to
             DEFPA still interrupting.
    
             This problem is corrected in OpenVMS Alpha V7.0
    
          o  "ACCVIO" crashes in the LAN driver  code  (varying  offsets  on
             different Ethernet only drivers) with R5 equal to zero.
    
             This problem is corrected in OpenVMS Alpha V7.0
    
          o  Modify the ISA Token Ring driver to allow multiple adapters  to
             be used in a system.
    
              o  Hang  creating  CSMA-CD  or  FDDI  STATION  on  valid   but
                 non-existant comm port.
    
              o  Crash in LAN modules creating CSMA-CD or  FDDI  STATION  on
                 invalid comm port.
    
              o  CSMA and FDDI Port Ethernet Protocol Types  are  improperly
                 encoded.
    
              o  CSMA Port MAC Addresses are improperly encoded.
    
              o  Last Set Station ID encoded correctly.
    
              o  PHY Port Station Type incorrectly reported.
    
             These problems are corrected in OpenVMS Alpha V7.0
    
          o  Machinecheck , bugcheck(ICONIODB) crashes when  DEFPA  in  use.
             Crashed  in  EXCEPTION+0015D1C  offset.  Console version 4.1 is
             installed for DEFPA support.
    
             This problem is corrected in OpenVMS Alpha V7.0
    
          o  ACCVIO"  crash  if  physical  memory  is  not  available   when
             configuring the DEFPA, DEFEA, DEFTA and DEFAA.
    
             This problem is corrected in OpenVMS Alpha V7.0
    
          o  BUGCHECK NETDLLERR  crash  in  SYS$FADRIVER+0031F8.   The  SHOW
             LAN/DEV=FA  displays  the  "Last error CSR" field equal to 606.
             The system will also have more than 2 gigabytes of  memory  for
             this problem to appear.
    
          o  The handling of more than 6 multicast  addresses  per  user  is
             incorrect and may cause pool corruption and more likely just an
             accvio and  crash.   Also,  when  using  the  HLL  system  code
             debugger, multiple connections from the same node do not work.
    
          o  System crash during startup or shutdown at  NET$FDDI+50DD  when
             trying to access an FDDI network management data structure that
             does not exist.  It is possible for a DECnet-OSI user to create
             an FDDI station with CSMACD Network Management data structures.
    
          o  When stopping LAN protocols, some will not be removed from  the
             multicast table.
    
          o  INVEXCEPTN Bugcheck with DE205 @ PC 000B0004  0000.   Crash  in
             ERDRIVER, LAN$COMPLETE_VCRP_NOPC using PHASE IV ADDRESS TRUE in
             NCL routing script.
    
             This problem is corrected in OpenVMS Alpha V7.0
    
          o  DE450/DE500 adapters do not recognize station hardware  address
             if more than 16 multicast addresses are enabled.
    
          o  Allocating a local  data  structure  and  overwriting  existing
             pointers  causes 106 bytes of memory to be "lost" when deleting
             the last user of the port.
    
          o  When booting an 8200/8400 over  the  DEFPA,  the  boot  process
             hangs  immediately  after  the  transition to the runtime DEFPA
             driver, at the point of checking the status of the system disk.

    Problems addressed in the ALPLAN02_062 kit:
    
          o  Separate the ALPBOOT01_062 remedial kit into separate kits for
             LAN and BOOTDRIVER fixes.
    
    
    Problems addressed in the AXPLAN01_062 kit:
    
          o  This kit provides support for DE203, DE204, and DE205 Digital
             Ethernet ISA Bus Adapters.
    
             This information replaces Section 4.11.2.2 in the OpenVMS
             Version 6.2 Release Notes.
    
             To enable support for DE203, DE204, and DE205 Digital Ethernet
             ISA Bus Adapters, a device must be configured.  Then the system
             must be shut down and rebooted.
    
             Currently OpenVMS Alpha does  not  support  multiple  adapters.
             The  DE203, DE204, and DE205 ISA LAN devices must be configured
             with a port address (iobase0) of 300 (hex), the base of adapter
             memory  (membase0)  should  be d0000 (hex), and a memory length
             (memlen0) of  10000  (hex).   These  ISA  LAN  devices  can  be
             configured in one of the following ways:
    
                 Using the console isacfg command
    
                 Using the data file, SYS$MANAGER:ISA_CONFIG.DAT
    
    
             The following examples are specific to DE203, DE204, and  DE205
             devices.   For  more information about configuring ISA devices,
             refer to the OpenVMS Version 6.2 Release Notes.
    
             To configure an ISA LAN device using the isacfg command at the
             console prompt do the following:
    
                  >>> isacfg -slot 1 -etype 1 -enadev 1 -irq0 5 -iobase0 300
                    -membase0 %Xd0000 -memlen0 %x10000 -handle "DE205" -mk
    
    
             The command ("-mk") makes an isacfg entry for the ISA device at
             slot  1.   It  is  a  singleport  type of device (-typ 1).  The
             "-handle" parameter tells the operating  system  what  type  of
             device  it is and must be set to "DE205".  The iobase should be
             set to 300(hex), the base of adapter memory should  be  set  to
             D0000(hex)  and  the  length of adapter memory should be set to
             10000 (hex).
    
             To    configure    an    ISA    LAN    device     using     the
             SYS$MANAGER:ISA_CONFIG.DAT  file,  you must enter the following
             information:
    
                 [ERA0]
                 NAME=ER    ; Device name
                 DRIVER=SYS$ERDRIVER  ; Driver name
                 NODE=1    ; Slot #1
                 IRQ=5    ; IRQ 5
                 PORT=(300:f)   ; 15 bytes starting at 300 (hex)
                 MEM=(D0000:10000)  ; 64 bytes starting at D0000 (hex)
    
    
    Problems addressed in the ALPBOOT01_062 kit:
    
          o  Digital  has  determined  that  a  condition  exists  in   some
             PCI-Ethernet  interfaces  in which there is an extremely remote
             possibility for data corruption  during  network  transmission.
             Digital has received no customer complaints to date, but rather
             first encountered the problem during internal  product  testing
             and  analysis.   This  specific  condition  exists when the PCI
             interface is set to a DMA burst length of 0  or  32  longwords.
             Using  a  DMA  burst  length of 1, 2, 4, 8 or 16 longwords will
             eliminate this condition.  To address this concern, Digital  is
             making  available a driver patch and considers its installation
             mandatory for all affected systems and options to optimize data
             integrity.    No   hardware   modification  or  replacement  is
             necessary.
    
             This condition only exists under  the  Digital  UNIX  operating
             system  V3.2C  and  OpenVMS  Alpha  V6.1  (and  variants,  i.e.
             V6.1-1H1,  V6.1-1H2)  and  V6.2.   Higher-level  protocols  and
             layered  applications  may,  in fact, detect the corruption and
             retry the data transmission with some negligible affect on data
             throughput.   Windows  NT has a default setting of 16 longwords
             for the DMA burst length.  This does not pose a risk  unless  a
             customer were to change this setting.
    
             The system and option products from Digital that are impacted
             by this condition include:
    
                 DE434 PCI-Ethernet option       AlphaServer  400 system
                 DE435 PCI-Ethernet option       AlphaServer 1000 system
                 DE450 PCI-Ethernet option       AlphaServer 2000 system
                 AlphaStation 200 system         AlphaServer 2100 system
                 AlphaStation 250 system         AlphaServer 8200 system
                 AlphaStation 400 system         AlphaServer 8400 system
                 AlphaStation 600 system
    
             For OpenVMS Alpha users, this condition  exists  in  V6.1  (and
             variants)  and  V6.2.  Digital plans on providing the corrected
             driver in all OpenVMS Alpha factory installed  software  as  of
             early  December  and  in  the V6.2-1H1 hardware release and the
             V7.0 release scheduled for distribution  in  January  1996,  as
             well.   Because  the OpenVMS operating system drivers have this
             parameter hard coded, it is not possible to change  it  without
             loading a new driver.
