Lenovo Y450 BIOS flashing

I already install Windows Vista on Y450 and flash the new BIOS driver (version 28).

But I want using Windows XP, how can I install the previous version of BIOS? Because when use Windows XP CD for boot, my Y450 had GREEN screen, so I think it's the fault of BIOS flashing.

Thanks.

Re: Lenovo Y450 BIOS flashing

Once a BIOS is flashed you cannot go back to a previous BIOS version. You would need a new motherboard...
