    Flashing the wrong bios was what bricked the laptop. Now I'm trying to put back the original one, from the manufacturer's website that I'm certain works with the computer. However the file itself is larger than the bios memory. I assume that the flash update tool doesn't write the whole file on the chip but I'm not sure which part is what I need. I can't use the flash update tool because the computer won't boot at all, even though power works fine. I'm using a ELNEC SEEprog.
    I ran into the Phoenix Mod Tool in my search for something that would make sense of the file and it seems to read it correctly, but I still have no idea which part to use, so I was hoping people with more experience here might have some idea.

    The BIOS "W760CUH.11" is the BIOS.ROM + Platform Data. Here's a couple threads on the subject.

    But, I took a peak at yours and the "NAPI" string doesn't appear to be in the middle of the BIOS. What you should try is to figure out the correct size of your memory chip and "cut" that from the beginning of your BIOS file. The "NAPI" string should be a multiple of 512kB (80000h) away from the beginning of the file.

    Also I'm not a hardware guy, but you might actually need a different EEPROM programmer...according to the first thread I linked. Good luck!
