#ú : ´ V ¾ À X % r ! " B@ ¹ SET CONFIGURATION
Initially, the Diagnostic attempts to gather CONFIGURATION
information from the board itself. If no information can
be obtained, factory setting values are used.
Changing any parameter in SET CONFIGURATION only changes the
value used by the Diagnostic.
If the F10 key is pressed, the program will attempt to install
the current values into the board being diagnosed.
; 9 BOARD SELECTION
To allow Diagnosing more than one board at a time,
the Diagnostic builds a list of all the adapters
it thinks are installed in this machine.
Use the Up/Down Arrows to highlight the desired board
and press
Or use the board number (e.g. 1) as a 'Hot' key to
automatically select a board.
The Internal Loopback Test is designed to
isolate hardware failures with little or no user intervention.
The test will use all appropriate loopback
modes (i.e. Loopback mode 1 for 8390). The
test will verify data path integrity to the
point of the FIFO in the 8390. Next, it
will verify CRC generation and recognition
logic. Finally, it will verify address
recognition logic.
The 'Basic Adapter Test' performs tests on the following:
1) I/O Port Accessibility
2) LAN Address ROM
3) On-board RAM
4) Network Controller Registers
5) On-board ROM (if installed)
6) Internal Loopback
7) Interrupt Generation
For a more detailed explaination press PAGE DOWN.
64 1) I/O Port Accessibility
This test verifies the current Base I/O Address
by using it to identify a working LAN Adapter.
Press PAGE DOWN for next I 2 0 ö 2) LAN Address ROM
The current Base I/O Address is used to computes a checksum on the LAN Address ROM.
The computed value is compared against that
stored in the adapter.

First, the current RAM Base Address is
checked for out of range conditions.
Next, the current RAM Base Address is
used to test for conflicts with RAM or
ROM on other devices in this machine.
Finally, the RAM itself is tested.

The current Base I/O Address is used to
perform write/read/verify tests on the
registers in the LAN controller.

If ROM is enabled on the current adapter,
first, the current ROM Base Address is
checked for out of range conditions.
Next, the current ROM Base Address is
used to test for conflicts with RAM on
other devices in this machine.
Then, the user is alerted if the installed
ROM does not have a Boot ROM signature or
does not have a valid Boot ROM checksum.

Internal tests are performed on the LAN
controller hardware.
Note: Activity on a live network may
interfere with Internal Loopback
data.
For accurate results, use a
null terminated T-connector.

20 £ 7) Interrupt Generation
The current IRQ Interrupt level is used
to unmask the required interrupt and
install an interrupt vector to a interrupt
service routine in this Diagnostic.
Then a packet is transmitted and the
Diagnostic senses whether or not the
interrupt service routine was called.
Note: The LAN Adapter must be properly
terminated.
Press PAGE UP for previous 20 &INTERRUPT TEST
This test will verify all aspects of the
interrupt path. First, the PC is set up to
handle the interrupt. This is done by
unmasking the IRQ line into the PC interrupt
controller chip and setting up the interrupt
service routine in the CPU's interrupt vector
table. Then the LAN controller chip is set up to transmit a packet and interrupt the PC when it is done. When the interrupt service
routine is executed, the
'Interrupt Test Passed' message is placed on
the screen.
Check Method - Controls the method of packet verification
when running Respond/Initiate Test Messages.
Quiet Errors - Stop some errors from suspending execution.
Those errors will be logged only in the
Statistics.
Auto Clear Stats - Controls whether or not statistics are
cleared each time Respond to Test Messages
is executed.
In order to run this test, another node on the same network
must be using 'DIAGNOSE' and have 'Respond to Test Messages'
running from the Main Menu.
Test Messages are sent to and received from the current
Responder Node. The received packets are fully compared
to those sent.
Total Test Message Frames sent and received are continuously
updated.
6 4 ( RESPOND TO TEST MESSAGES
This will wait for a Test Message to be received
from another node on the same network using
'DIAGNOSE' and running 'Initiate Test Messages'
from the Main Menu.
All received Test Messages are echoed back to the
Initiator.
Pattern - This is the information in the Test Messages being
(hex) sent and received. The data is repeated through
the whole message. By making each Initiator send
different information, comparing the received data
against the sent may reveal network problems.
Iterations - Number of Test Messages to be sent and received.
Choose 'Non-stop' to run forever.
Frame Length - Size of the Test Messages being sent.
Special sizes may be typed in manually.
Check Method - Controls full packet verification after the
message has been echoed by the responder.
Press PAGE DOWN for more...
Dest Addr - Responder Network Address may be manually
entered.
Transmit Retries - Number of times to retry any transmit
before showing an error.
Receive Timeout - Time to wait for a Response to a Test
Message before retransmitting.
Quiet Errors - Stop some errors from suspending execution.
Those errors will be logged only in the
Statistics.

Before any Diagnosing may be performed, a board must be
selected. Enter 'Choose a Board to Diagnose' and select
your board or 'Exit to Operating System'.
This Entry Menu will appear only once per Diagnostic session.
However, you may 'Choose a Board to Diagnose' from the Main
Menu at any time.
Very nice! Thank you for this wonderful archive. I wonder why I found it only now. Long live the BBS file archives!
This is so awesome! 😀 I’d be cool if you could download an entire archive of this at once, though.
But one thing that puzzles me is the “mtswslnkmcjklsdlsbdmMICROSOFT” string. There is an article about it here. It is definitely worth a read: http://www.os2museum.com/wp/mtswslnk/
