NOTE: An OpenVMS saveset or PCSI installation file is stored
on the Internet in a self-expanding compressed file.
For OpenVMS savesets, the name of the compressed saveset
file will be kit_name.a-dcx_vaxexe for OpenVMS VAX or
kit_name.a-dcx_axpexe for OpenVMS Alpha. Once the OpenVMS
saveset is copied to your system, expand the compressed
saveset by typing RUN kitname.dcx_vaxexe or kitname.dcx_alpexe.
For PCSI files, once the PCSI file is copied to your system,
rename the PCSI file to kitname-dcx_axpexe.pcsi, then it can
be expanded by typing RUN kitname-dcx_axpexe.pcsi. The resultant
file will be the PCSI installation file which can be used to install
the ECO.

ECO KIT SUMMARY:
An ECO kit exists for LAN on OpenVMS Alpha V7.2-1. This kit addresses the
following problems:
Support Added for Compaq 3X-DAPBA-FA and Compaq 3X-DAPCA-FA ATM Adapters:
o The 3X-DAPBA-FA and the 3X-DAPCA-FA are PCI based ATM adapters for
Alpha-based systems that provide high performance PCI-to-ATM
capability. The 3X-DAPBA-FA adapter offers a 155 Mbps fiber
connection; the 3X-DAPCA-FA adapter offers a 622 Mbps fiber
connection.
The datalink drivers for these adapters function in a new OpenVMS
ATM environment. The new OpenVMS ATM environment is fully
compatible with the existing legacy ATM support and allows both ATM
environments to be configured on a single system. Additionally,
the LANCP management interface is the same for both ATM
environments. The following images/files support the new OpenVMS
ATM environment:
Images Affected:
- [SYS$LDR]SYS$LAN.EXE
- [SYS$LDR]SYS$LAN_CSMACD.EXE
- [SYS$LDR]SYS$LAN_ATM.EXE
- [SYS$LDR]SYS$LAN_ATM4.EXE (new)
- [SYS$LDR]SYS$$ELDRIVER4.EXE (new)
- [SYS$LDR]SYS$$HWDRIVER4.EXE (new)
- [SYSEXE]SYS$CONFIG.DAT
- [SYSEXE]LANCP.EXE
- [SYSEXE]LANACP.EXE
Adapter Requirements:
These adapters require a great deal of non-paged pool, and
therefore, care should be taken when configuring them. The
following restrictions apply to these adapters:
+ For each 3X-DAPBA-FA adapter, Compaq recommends increasing
the SYSGEN parameter NPAGEVIR by 3000000.
+ For each 3X-DAPCA-FA adapter, Compaq recommends increasing
NPAGEVIR by 6000000.
To perform the above chagnes, add the ADD_NPAG_VIR parameter to
MODPARAMS.DAT and then run AUTOGEN. For example, on a system
with two 3X-DAPBA-FAs and one 3X-DAPCA-FA, you would add the
following line to MODPARAMS.DAT:
ADD_NPAG_VIR = 12000000
Adapter Restrictions:
o The adapter cannot be located on a PCI bus that is located
behind a PCI-to-PCI bridge. Systems that have this
configuration are the following:
+ Digital Personal AlphaWorkstation 600
+ AlphaStation 1000A
+ COMPAQ Professional Workstation XP1000
+ AlphaServer 2000 and 2100
o Classical IP is not supported with these new adapters.
o SDA does not correctly identify these new ATM/FORE adapters.
They are identified as "unknown adapters." This will be fixed
in a subsequent support release.
For additional information about the 3X-DAPBA-FA PCI HE155 ATM and
3X-DAPCA-FA PCI HE622 ATM adapters, refer to the following URL:

o Support has been added for unlimited chained transmit segments to
LAN drivers. Support for this functionality is a performance
enhancement for both IPv4 and IPv6.
Images Affected:
- [SYS$LDR]SYS$ERDRIVER.EXE
- [SYS$LDR]SYS$EWDRIVER_DE500BA.EXE
- [SYS$LDR]SYS$FXDRIVER.EXE
- [SYS$LDR]SYS$ESDRIVER.EXE
- [SYS$LDR]SYS$HCDRIVER.EXE
- [SYS$LDR]SYS$HWDRIVER.EXE
- [SYS$LDR]SYS$FADRIVER.EXE
- [SYS$LDR]SYS$FCDRIVER.EXE
- [SYS$LDR]SYS$FRDRIVER.EXE
- [SYS$LDR]SYS$EXDRIVER.EXE
- [SYS$LDR]SYS$FWDRIVER.EXE
- [SYS$LDR]SYS$EWDRIVER.EXE
Problems Addressed In VMS721_LAN-V0200:
o A system can experience multiple DEMFA hardware errors
resulting in loss of the network connection to that system.
Images Affected: [SYS$LDR]SYS$FXDRIVER.EXE
o A System can crash when an INVEXCEPTN bugcheck at
SYS$FRDRIVER+11F50 when attempting to use a LAN UCB (unit
control block) after it has been deassigned.
Images Affected: [SYS$LDR]SYS$LAN.EXE
[SYS$LDR]SYS$LAN_CSMACD.EXE
[SYS$LDR]SYS$LAN_FDDI.EXE
[SYS$LDR]SYS$LAN_ATM.EXE
[SYS$LDR]SYS$LAN_TR.EXE
o If the LANCP command SET DEV/MIN=n/MAX=n is used to set the
minimum and maximum receive buffers to the same value, the
DEGPA LAN driver ([SYS$LDR]SYS$EW1000A.EXE) may steadily lose
pool in 5k byte increments until pool is exhausted. This
generally results in a system crash.
Images Affected: [SYS$LDR]SYS$EW1000A.EXE
o After entering a STOP/IP/ISA1 command from within the TCPWare
management interface, a NETDLLERR crash occurs in LSB$L_XMTCNT
-1
Images Affected: [SYS$LDR]SYS$EZDRIVER.EXE
o A packet is delayed from processing in the DE500 receive ring.
The packet is completely done, but it does not get processed
until another packet is received. As a result, the connection
is dropped.
Images Affected: [SYS$LDR]SYS$EWDRIVER_DE500BA.EXE
[SYS$LDR]SYS$EWDRIVER.EXE
o APB translates WWIDs specified in BOOTED_DEV and DUMP_DEV to
determine the disk's unit number. APB does not perform this
function for WWID0.
Images Affected: [SYSEXE]APB.EXE
o During the processing of a recursive bugcheck, the DUMP_DEV
variable appears to have changed after being verified. The
change then re-directed the dump write from the correct DOSD
disk to the system disk.
Images Affected: [SYSEXE]APB.EXE
[SYSEXE]DEBUG_APB.EXE
o A 'Kernel stack not valid' bugcheck occurs during shutdown.
Images Affected: [SYS$LDR]SYS$EW1000A.EXE
o On some systems, the PCI FDDI adapter (the DEFPA) halts with a
fatal hardware error. When the driver attempts to restart the
DEFPA, the driver detects either a parity error being reported
by the DEFPA, or it detects a command failure, which prevents
the driver from getting the DEFPA restarted successfully.
Images Affected: [SYS$LDR]SYS$FWDRIVER.EXE
[SYS$LDR]SYS$FRDRIVER.EXE
[SYS$LDR]SYS$FADRIVER.EXE
o The LAN Device Characteristics block (LDC) contains the device
line speed, which applications may use to determine how fast
the device is running. The Token Ring driver sets the line
speed at 16, even if driver is set to 4 megabits. The change
enables the driver to set the speed in the LDC to 4 or 16
megabits, whenever a new speed is determined.
Images Affected: [SYS$LDR]SYS$IWDRIVER.EXE
[SYS$LDR]SYS$IRDRIVER.EXE
[SYS$LDR]SYS$ICDRIVER.EXE
o A multitude of data overruns causes very poor network
performance when running from a DE504 in ES40 to a DE602 in
GS160.
Images Affected: [SYS$LDR]SYS$EIDRIVER.EXE
o The system can crash when an interrupt occurs after
deallocating the buffer.
Images Affected: [SYS$LDR]SYS$LAN.EXE
[SYS$LDR]SYS$LAN_CSMACD.EXE
[SYS$LDR]SYS$LAN_FDDI.EXE
[SYS$LDR]SYS$LAN_TR.EXE
[SYS$LDR]SYS$LAN_ATM.EXE
[SYS$LDR]SYS$EWDRIVER_DE500BA.EXE
[SYSEXE]LANCP.EXE
o CSMACD can crash when executing an NCL script.
Images Affected: [SYS$LDR]SYS$EWDRIVER.EXE
[SYS$LDR]SYS$EWDRIVER_DE500BA.EXE
[SYS$LDR]SYS$EIDRIVER.EXE
[SYS$LDR]SYS$FWDRIVER.EXE
[SYS$LDR]SYS$FCDRIVER.EXE

[SYS$LDR]SYS$FADRIVER.EXE
[SYS$LDR]SYS$EW1000A.EXE
[SYS$LDR]SYS$ELDRIVER.EXE
[SYSEXE]SYS$CONFIG.DAT
[SYSEXE]LANCP.EXE
o The LAN device line speeds are displayed incorrectly with
NISCACP.
Images Affected: [SYS$LDR]SYS$EWDRIVER.EXE
[SYS$LDR]SYS$EWDRIVER_DE500BA.EXE
[SYS$LDR]SYS$EIDRIVER.EXE
[SYS$LDR]SYS$FWDRIVER.EXE

[SYS$LDR]SYS$EW1000A.EXE
[SYS$LDR]SYS$ELDRIVER.EXE
[SYSEXE]SYS$CONFIG.DAT
[SYSEXE]LANCP.EXE
o An INVEXCEPTN crash can occur in the SYS$EW1000A driver
following a SET HOST/LAT command.
Images Affected: [SYS$LDR]SYS$EWDRIVER.EXE
[SYS$LDR]SYS$EWDRIVER_DE500BA.EXE
[SYS$LDR]SYS$EIDRIVER.EXE
[SYS$LDR]SYS$FWDRIVER.EXE
[SYS$LDR]SYS$FCDRIVER.EXE

[SYS$LDR]SYS$EW1000A.EXE
[SYS$LDR]SYS$ELDRIVER.EXE
[SYSEXE]SYS$CONFIG.DAT
[SYSEXE]LANCP.EXE
o Increase the buffer_limit, from 100k to 500k, in the LANACP
startup command file to allow LANACP to start MOP on more LAN
devices without failure.
Images Affected: [SYS$STARTUP]LAN$STARTUP.COM
o The DE425 does not function on systems that do not have
mapping registers.
Images Affected: [SYS$LDR]SYS$ERDRIVER.EXE
PROBLEMS ADDRESSED IN VMS721_LAN-V0100 KIT
o Add support for XP1000 embedded Ethernet adapter.
Add support for the COMPAQ Professional Workstation XP1000
embedded Ethernet adapter.
The ADAPTER_NAME field in the COMPAQ Professional Workstation
XP1000 embedded Ethernet SROM is blank. Since, the boot and
runtime drivers are only aware of this field being blank for
the Digital Personal Workstation, these drivers will see the
COMPAQ Professional Workstation XP1000 as a Digital Personal
Workstation. The COMPAQ Professional Workstation XP1000 and
Digital Personal Workstation embedded Ethernets are not
programmed in the same way.
o Autonegotiation fails.
When the Tulip bootdriver determines that a 21143 chip is
present it checks the EEPROM to further identify the
controller type. If the EEPROM does not further identify the
controller, the driver checks if the system type is a Digital
Personal Workstation. If it is, the MAU type is determined
and the controller is programmed accordingly. The XP-1000
platform does not identify the controller in the EEPROM and is
not a Digital Personal Workstation so the bootdriver was
returning OFFLINE on a network boot.
