Finally, here is the working dump for boards with U1 chip only, after I remove the password, the custom logo and update it to the latest version A15.
For more BIOS'es problems you can always contact me at [email protected] or [email protected]
Tested and works 100%. Same as new.
Enjoy :D

You can download bios above.
 
Ok. I`ll tell you the hole story. So i bought this laptop ..that had a bios password. We tried to remove it ..but to be honest I`ve never flashed a bios chip. There was very hard to find a schematic..or anything that could help me to identify the bios chip. Until then a friend of mine toke the u7 chip and wiped. After that I was aleardy waiting the new chips with the bios already flashed. But because the u7 chip is wiped..it starts but will not boot or show anything on screen because of that chip. Is it worth fixing or shall I just buy another one? I`m a tehnician ..but this is the only thing i`ve never done ..like bios chips. thank you and sorry for bodering you.

Thank you,
With respect Ciprian Baroncea.
 
Thank you hyoucef72, i`ve done the u7. but i get just blinking light..and that means..process failure. shall i do the bios ? i need only u2 or u1 and u2 to flash the memory ?
 
Hy again. I`ve tried the files. and still i get process failure ..the led blinking...probably ..something else is wrong. . so any ideas .. what can i do next? :)
