@afinon I think the W7104VMS.357 is more correct than the W7104VMS.500 bios. They are all supposed to be for the board revision you have. the difference seems to be a slight board revision. The ERP in the serial for the W7104VMS.500 series is 040 (S/N:601-7104-030K0705007659) anf the W7104VMS.357 is for earlier revision. I have read that they are both adequate and the difference is largely options...
