I downloaded the BIOS file for my acer aspire 5580 model from Accer's website. (It contains several dlls, WinPhlash.exe and ZR1_3508.wph files among other files. (There is No *.fd or *.rom file) Having failed to do recovery from thumb drive, (It didn't work for me. When I press Fn+Esc and plug in the AC jack nothing happens (the power led don't blink). If I press the power button anyway, still nothing happen (it don't attempt to read from thumb drive) but the fans and lights turn on. Of course, there is no display (both external and internal)) So, I moved forward and soldered out the BIOS ROM chip to program it with hardware programmer. But the ROM file is little larger than chip size (1028 Vs 1024 KB). So, how to extract only the relevant section from the ZR1_3508.wph?
