Did you update from a USB device or Harddrive ? I have found that any USB drive bigger than 16Gb can cause an issue when flashing a bios from it.
If the bios was improperly written then there is not much you can do except request a new bios chip (your board has one that is socketed and not soldered). Go here and follow the instructions:

Thanks for the response, it was a 64Gb stick so perhaps that had something to do with it. disappointing that it frys the chip but guess thats just how it goes sometimes
