Just googled this problem and came here, so thought I'd drop in my 2p.

I've killed 2 MSI X58 Eclipses by this method now - first on .123 BIOS and second on .125 BIOS using M-Flash. Apparently MSI has problems with its M-Flash and recommend not to use it for the time being.

I can't even hot flash because it's soldered to the board
