DA0LZ5MB8B0 with Intel ES (Lenovo)

[piernov]

Hi, anyone ever heard of Lenovo engineering sample motherboards?
Just came across a DA0LZ5MB8B0 (ie. Quanta LZ5 REV:B) motherboard which isn't referenced anywhere on the Internet. You can mostly find REV and I've seen some references to REV:A1 and REV:C.

The BIOS indicated a Lenovo Z380 laptop, which has a completely different motherboard. The Quanta LZ5 series is found in Lenovo U330.

Also this motherboard has an Intel Engineering Sample CPU (from Haswell generation, maybe a Core i5 equivalent, not sure).

Tried to flash the BIOS from a Lenovo U330T and it seems it doesn't boot anymore (I might have fucked up the flash).

This computer freezes when plugging in a SD card (among other "strange behaviour").

Will post BIOS dump and pictures later.
