Title: Release Note: CS/100 booting from diskette Ver 20060
Date: 3/30/87

Copyright 3Com Corporation, 1991.  All rights reserved.


Enclosed is the SW/100-A/BSC Version 20060 diskette. This
diskette is your distribution copy of SW/100-A/BSC Version 20060
and should be used only to copy the system software onto the
master diskette. The master may then be used to update the
current working diskette.

Bridge recommends the following procedure to update your system
to Version 20060:

1.  Connect your terminal to port 0 of the CS/100.

2.  Insert the SW/100-UTIL Version 36000 diskette in the CS/100
disk drive, then press the Reset switch. After the Utilities
diskette is finished booting, press the following sequence on
the keyboard:

<RETURN>.<RETURN>

3.  After the CS/100 has finished its self-test, remove the
Utilities diskette.

4.  Use the following command to copy the software from the
SW/100-A/BSC Version 20060 diskette to your SW/100-A/BSC
Version 12010 or later diskette:

> co -p <n> <CR>
where n is a number of updated diskettes to be made.

5.  When the system prompts for the first and last block numbers,
enter the numbers as follows:

> First block? 0  <CR> > Last block? 140 <CR>

6.  The following message appears on the screen:

Insert Master Disk #n (hit <CR> to continue, q to quit)

7.  Insert the SW/100-A/BSC Version 20060 diskette in the disk
drive.  Then press the return key.

8.  If the read completes successfully, the following messages
appear on your screen:



Reading ... OK Insert copy #n and hit return key
If the message "read error" appears instead, contact an
authorized Bridge service representative for assistance.
Otherwise, follow the instructions.

9.  Remove the SW/100-A/BSC Version 20060 diskette and insert
your SW/100-A/BSC Version 12010 or later diskette in the disk
drive, then press the return key.

10. If the copy completes successfully, the following messages
appear on your screen:

writing ... verifying ... OK copy completed

11. Remove the diskette and label it "SW/100-A/BSC MASTER VERSION
20060". Store the distribution copy of SW/100-A/BSC Version
20060 in a safe place.

12. The SW/100-A/BSC Version 20060 master diskette may now be
used to update current working diskettes using the "co <n>"
command.

New Features

The following features, which were not present in SW/100-A/BSC
Version 20050 or earlier, have been implemented in SW/100-A/BSC
Version 20060:

1.  In addition to the SETDefault command, the SET command can be
used to alter the buffer size of an individual port. For
instance, to change the current buffer size of a port to 56
bytes, type:

set BUffersize = 56

To change the buffer size of the host, the REMoteSET command
can be used with the same syntax shown above.  Setting the
buffer size to be smaller than the system buffer size, which
is usually 82 bytes, will actually create a buffer of the
specified size. If the specified value is greater than the
system buffer size, more buffers of the system buffer size
will be created instead of a bigger buffer.

The SET command will not take effect immediately during a
session. The additional buffers created by the command will
not be used until the buffers currently allocated to the port
have been exhausted.

2.  It now takes 4 seconds for the Communications Server to
deliver the audit trail data to the NCS. It used to take 90
seconds.



The 4-second timer can be sysgenned. This is done by
modifying the Statistics Monitor timer value. Please refer to
the Configuration Guide for further information.

3.  The server will accept from the netmap packet a clock value
that is lower than the current value. For example, if the
clock on the NCS is set back to year 1970, all the system
clocks of the servers on the network will be changed within
45 seconds to this new value.

Bugs Fixed

The following problems have been corrected in SW/100-A/BSC
Version 20060:

1.  The audit trail records now show the actual number of rotary
ports used. In the past, the rotary ports used count was
always zero according to the audit trail records.

2.  It is no longer possible for a port to be trapped in the
WAIT-FOR-CONNECT state forever or for the PVC (Permanent
Virtual Circuit) to suddenly stop working.

3.  The data link drivers can now detect all known deadlock
situations properly.  Running the servers on a noisy network
will not crash the servers or cause the servers to drop from
the netmap.

Known Problems

The following is a list of current problems in SW/100-A/BSC
Version 20060:

1.  If you have not updated all of your CS/100s to SW/100-A/BSC
Version 20000 or later, a connection from a CS/100 that runs
SW/100-A/BSC Version 17100 or SW/100-A/BSC Version 18610 to a
CS/100 that runs SW/100-A/BSC Version 20000 or later may
cause a delay of approximately four seconds.

2.  If the FlowControlTo and FlowControlFrom parameters are both
set to None, resetting one of the parameters to XonXoff or
ENQACK causes the other to be automatically set to XonXoff or
ENQACK. Note that this problem does not occur for the other
two options (None and CTSRTS).

3.  If your working diskette was SW/100-A/BSC Version 20030 or
earlier before being updated to Version 20060, the
LogoffString may contain garbage characters when the software
is first booted. In order to eliminate these garbage
characters, use the following command:



SETDefault LogoffString = ""

4.  Due to a memory limitation, the SHow CONFiguration and SHow
MACro commands no longer display output in alphabetical
order.

Procedure to Sysgen SW/100-A/BSC Version 20060

Following is the procedure for running the sysgen program on the
CS/100. For further information on menu displays and parameters,
please refer to the  Configuration Guide.

System generation is not required before you install the
software. It is used to alter the values of certain parameters.
Bridge does not recommend altering those values without a
specific need.

1.  Connect a terminal to the console port of the CS/100.

2.  Insert the SW/100-A/BSC Version 20060 diskette in the CS/100
disk drive, then press the Reset switch. The CS/100 displays
the following messages:

Power-up V1.0 MCPU-passed   <MCPU Firmware Version> EC-
passed     <Ethernet address>   <EC Firmware Version> SIO
# 1 - passed <SIO Firmware Version> SIO # 2 - passed (or
not present) SIO # 3 - passed (or not present) SIO # 4 -
passed (or not present) Bridge Communications MCPU
Monitor

3.  After the above messages, the system displays a ">" prompt.
Enter "gn" and press the return key.

4.  The Sysgen Utility V2.0 menu will appear on the screen.
Enter 1 to select View/Alter Module Parameters, then press
the return key.

5.  To display a parameter module, enter the number of the module
as it appears in the Module Select Menu, then press the
return key.

6.  After the list of parameters appears on the screen, you can
change the value of a parameter by entering its number. Then
enter the new value of the parameter at the prompt and press
the return key.

7.  Press <ESC> to return to the Module Select Menu.

8.  After system generation is complete, enter 2 to save all the
parameters.



9.  Enter 3, then press the return key to exit to the monitor.
