Asus ROG Crosshair VIII: BIOS update

A while ago I upgraded my mainboard and CPU to a Ryzen setup (mainly so I could squeeze a few more VMs on it for work), using an Asus ROG Crosshair VIII for the motherboard, and for the most part it’s not skipped a beat, except for one minor issue: sometimes when I go to switch it on, it does nothing. I have to switch off the 240v AC switch on the back of the PSU, then switch it back on in order for the machine to start normally.

So I decided to see if a BIOS update would fix it on Tuesday, and set about performing it. I downloaded what I thought was the correct one, and rebooted into the UEFI setup to use the EZFlash. Navigate to the SSD where I saved it, and… “not a valid UEFI image”.

Did I download the wrong firmware? Maybe, there’s a wifi and a non-wifi version and it’s possible I grabbed the wrong one, so I made sure I downloaded the correct one and tried again… nope, still nothing.

After some experimentation and Googling, I figured out that even though the EZFlash3 software is able to browse around NTFS partitions, it’s unable to read files from it. So I threw the firmware on a FAT-formatted USB thumbdrive and tried again and this time it worked.

It’s been a few days and so far it seems to have solved the issue. We’ll see.
