It's designed by Toshiba but manufactured by HannStar the part number for the motherboard is DA0TZ2MB8X0 (where "X" is the revision code) you will need to disassemble your laptop to see which revision you need, it can be A,B,C...), so far i have seen up to revision "D"
The bios chip is located close to the center in the top section of the motherboard and there is a "U1" mark close to the chip, the chip manufacturer is Windbond part number is 25X80VSIG.
