Comments
Installation on X250 from USB-CD/DVD-ROM failed. eCS v2.1 started up to maintenance screen bot no HDD was found. eCS v2.2 Beta II even did not start up from CD/DVD-ROM. I tried to clone my existing system using DFSee and finally worked after some trouble with partition alignment. Status now on X250 is a working eCS v.2.1 with ACPI showing 4 cores, full support of native screen resolution via PANORAMA, working USB (mouse and thumb drive tested as well as USB keyboard in docking station) after disabling USB3.0 in BIOS.
