I want to upgrade BIOS for an Asus Z87-A motherboard with Haswell Core i7 -4770 processor. The latest BIOS version on Asus website is from June 2014. But I don't want to use the BIOS version that includes microcode that disables TSX as per errata HSW136. Can I safely assume that since this errata was published in August 2014, the BIOS upgrade doesn't contain that microcode? I just want to be sure since the owner of this motherboard will kill me if I manage to disable TSX on his computer.
