Yeah, Softpedia still hosts the file too. But ASRock should put a notice - not just silently removing the update. I think I ll just wait and see what their response will be.
ASRock support came back regarding this issue. Apparently the P3.70 version of the BIOS had issues with some Xeon CPUs (unable to boot). A new BIOS version is to be released shortly. I felt their response was honest, so I am happy with that.
