I tried the latest bios update for the X220, from 2015-05-27 It does not resolve the issue. Also, it required some hoop jumping, as they only provide a bootable cd (x220s do not have CD drives) and a windows program. However, if others are interested, this handy perl script: http://userpages.uni-koblenz.de/~krienke/ftp/noarch/geteltorito/ can be used to extract the el torito image from that .iso to a file, that can then be dd'd to a USB stick and update the bios. -- Allan Jude
