NB The 'Security' screen lets you enable or disable 'Boot from USB Devices'.
The F12 key will bring up a boot menu. You then move on to a screen titled: Please select boot device:. My X300 had a USB pen drive inserted and a CF card fitted. With this combination the menu of options is:
You can select any of the items but, what ever you select this time, it does not change the default behaviour of the BIOS.
The Compact Flash card carried a version of eLux. (eLux support now migrated to unicon-software)
