Download the BIOS, format a USB fat32 and rename the BIOS to M11H.cap...nothing else on the USB stick Put the stick in the USB port labeled BIOS and without turning the machine on depress the BIOS flashback button for a few seconds. Should start flashing and continue to flash for a couple of minutes until done. If it starts to flash then stops either the USB is in the wrong port or the file is not named correctly.
The problem with the internet update is they may have the support page updated but not the internet update. I always use the USB method.
