Hi, you can download the BIOS file from the support site, then unzip it and copy to a external device like USB. Then go into BIOS and find EZflash, then choose the BIOS file you want to update.
This will be very easy~
Edit by cl-Albert: Hope it's okay to edit your post Davy, but I usually skip the external USB drive and download to and flash the bios from the hard drive, so wanted to check if you had any opinion about this? Thanks.
