Hi,

I have a supermicro X8DT6-F/DTE-F motherboard with a broken IPMI BMC controller (AFAICT).  The bios at POST sits for a very log time trying to "initialize IPMI" and eventually fails.  I have contacted supermicro tech support about reflashing the BMC IPMI software with one of their online images, but have been unsuccessful using the recommended yafukcs tool.  The tool gives the errors..

Error in SendTimedImbRequest
Error in Getting FMH Info
Error in FirmwareInfo

The supermicro techs gave up quick and simply said RMA it.

I was wondering if anyone has had success using flashrom to reflash the Nuvoton WPCM450RA0BX chip that is on this board ?

If so could you explain how and which programmer you used ?  I'm also interested in general approaches even if this has not been done before to try.  At this point I don't think I can make things any worse. 

./flashrom -V --programmer internal
flashrom v0.9.7-r1711 on Linux 2.6.32-358.18.1.el6.x86_64 (x86_64)
flashrom is free software, get the source code at http://www.flashrom.org

flashrom was built with libpci 3.1.10, GCC 4.4.7 20120313 (Red Hat 4.4.7-3), little endian
Command line (3 args): ./flashrom -V --programmer internal
