@Enforte, I have the lenovo model "s400" without the "u" at the end.
I downloaded this same bios from here and from another page, and when executing it, it seems that it installs ... but when the machine restarts, the blue screen appears indicating "Insyde HD20 -Secure FlashError: Invalid Firmware ImagePlease press any key to reset system
Do you have any idea? The Windows 7 that I installed is the 32-bits. Did you install the W7 64bits ?
