Supermicro IPMI Firmware?
« on: November 08, 2013, 06:24:51 PM »
So, I've recently attempted to extract some supermicro IPMI firmware (from http://www.supermicro.com/support/resources/getfile.aspx?ID=2370 ).  It seems that it only managed to extract the web UI files, and that the actual Linux filesystem wasn't extracted.

Is there an option somewhere to extract all the parts of the firmware?   I know there's a linux image in there, I can extract it manually with binwalk.


# binwalk SMT_X9_238.bin

I should also note that making a minor change and putting the firmware back together resulted in bricking the IPMI controller.  I'm still trying to figure out how to recover from that.
