Michael Larabel's article gave this motherboard high marks. I always research hardware on Linux before buying.

And it performed quite well using arch Linux for about a week, then began allowing me to boot ONLY AFTER I log into BIOS. No change in BIOS is needed, just enter BIOS/exit BIOS, and boot continues successfully.

ECS support of course only supports windows, but a tech did helpfully suggest I install windows to see if the boot problem occurred.

ECS only supplies windows-based firmware upgrade utilities. There is not even a dos-based exe. My request as to whether they might supply a raw BIOS image was ignored.

Does anyone know of any way to perform firmware upgrade on an ECS Z77H2-A2X without having to buy some really overpriced utility (i.e., Windows 7 or 8)?
