Use pflash from a shell on the BMC. The web UI has these formats there and they just get in the way.

pflash and a raw image (the .pnor that op-build produces) will do the “make the flash chip EXACTLY THIS” nice heavy hammer approach and get rid of any “smarts” that the web UI has.

The only practical thing you lose by using pflash is the preservation of NVRAM, which is only going to have any settings you set in petitboot for boot device preferences.
