<br><font size=2><tt>I went looking for new firmware for this HCA. The
OpenIB Wiki entry on updating the Mellanox firmware says to check the board
revision by doing </tt></font>
<br>
<br><font size=2><tt> "cat /sys/class/infiniband/mthca0/board_id"</tt></font>
<br>
<br><font size=2><tt>which output nothing. An "od" on the
file shows only '0000000a' hex. </tt></font>
<br>
<br><font size=2><tt>Next I tried to find the board-id with the the "mstflint"
tool as described in the "installation cheat sheet", but when
I tried to build it under 'gen2/trunk/src/userspace/mstflint' I got a number
of compile errors. Evidently this system's installation of gcc 3.4.3 is
missing several 'c++' include files. I will have to investigate that
further.</tt></font>
<br>
<br><font size=2><tt>So I next built the "tvflash" utility under
'gen2/trunk/src/userspace/tvflash'. I was able to use this to display
some information about the board, but got an error:</tt></font>

<br><font size=2><tt>Lacking the Board-ID (PSID), I went to the Mellanox
firmware support site and tried to determine what firmware I needed based
on the information I did have (i.e. Lion Cub, PCI Express, 25208) and I
think that I need to load the following firmware:</tt></font>

<br><font size=2><tt>Michael, can you confirm this, based on what I have
described above?</tt></font>
