Andy's tool has got a problem with it. I have reported the issue. Needs to be fixed, a manually mod should be possible since PBE decomposes it fine. We''ll wait for Andy's update...a manually mod should be kept as last resort, since it would be time consuming to realise.
I can but only with an RW Everything Report that comes directly from a G450 Machine or Computer and not from a G550 machine.
If the bios would be for G550 you would find it there as well. I think it's not for your notebook! There is no bios yet. If you flash a wrong bios, you probably would have to send it away to repair it. I cannot recommend to try it. Do you want to try anyway? Edit: From where is the G450 bios? There is no bios at Lenovo site!
