Rebuilding IPMI firmware

Hello, Thanks for a great tool! I'm trying to customize the firmware for old IPMI server based on X9 platform. My platform motherboard is X9SRD-F. Official latest firmware on SM website is "SMT_X9_319.bin". I found one firmware "SMT_X9_364.bin" for slightly different motherboard (X9SRE-F) https://www.supermicro.com/en/support/resources/downloadcenter/firmware/MBD-X9SRE-F/BMC I was able to flash it with IPMI interface, however I find out that it is having some issue with IPMI java and support only x32 version of java =( I tried to flash SMT_X9_319.bin back again, but after flashing I can only see that IPMI open only 2 ports: 22 & 5900, so the web interface is not available anymore. When I flash SMT_X9_364 again, web interface is working.

I'm have a plan to modify SMT_X9_364 and add some missing library to this firmware to be able to support x64 version of java.

I follow the instruction and when I tried to extract firmware I see some wired symbols was add to the end of extracted files:
