A-10 SLC 5/03 (OS30x), SLC 5/04 (OS40x) and SLC 5/05 (OS50x) Firmware History
• Message Error Code (OS501 only)
After a Unix Server has defined the unsolicited “Client” IP address in
SLC 5/05, the Server is removed from the network. The SLC 5/05
“Client” messages continue to be initiated since the user program
re-triggers them on a message error. The “Client” messages normally
error out with a 0x10 error code (invalid command parameters),
probably since the Server’s IP address has been removed from the
“Client” IP table. However, the messages stop re-triggering after several
seconds indicating that the message was “done” with an error code
0x10.
The mother board firmware will add one feature to give more error
information for the MSG instruction. Two more bits (word 12 bit 0 and
word 12 bit 1) in control block are used to give the error information.
When daughtercard returns error code, .ER is set, bit 1 (word 12 bit 0)
in control block is set, error code, which is a non-zero value, will be put
into the control block. When daughtercard returns no error code, and
motherboard got an error code in the PCCC command reply, .ER is set,
bit 2 (word 12 bit 1) is set, error code, which is a non-zero value, will be
put into the control block. When daughtercard has no error return, and
motherboard get the right PCCC reply without error,. DN is set, bit 1
and bit 2 are reset error code in control block will be 0. Bits.ER, bit 1
and bit 2 will be reset once the MSG is enabled.
• Daughtercard Firmware Revision/Series Check (OS501 only)
A new feature will be added in the current release to check the daughter
card firmware revision/series. This feature will be implemented in the
power up. When the daughter card series is not same to a specific
number, or daughter card revision is not same to a specific number, a
non-user fault (0x3B) will occur. If series is 9999, no fault occurs.
• Expanded Channel 1 Diagnostic File (OS501 only)
The processor can support channel 1 diagnostic file. This diagnostic file
can be any user defined integer file, which file number is in the range of
9 to 255. The existing diagnostic information structure size in firmware
is 44 words. However, the new daughtercard supports 50 words
information. The 45th word contains the number of network storms
since the last power cycle. The 46th word to 48th word contains the
Ethernet hardware address. The 49th word and 50th word contains IP
address. In the new firmware release, the diagnostic information
structure in firmware will be expanded to 50 words to get all the channel
1 information from daughtercard to match daughtercard requirement.
• Update NETBSD TCP/IP Stack (OS501 only)
The Berkley NETBSD TCP/IP stack was recently ported over to the
1756-ENET module to replace the Berkley Software Distribution
