Re: fujitsu lifebook a555

I tried with ch341a writing everything ok but when it checks it says the chip was not matching the current document

Rename peste`s file to bios.bin ,or try some other alternative software, AsProgrammer,NeoProgrammer,Colibri,Flashrom

I tried with neoprogrammer and the verification gives a positive result, but when soldered on the main it turns on the LEDs for a second then they turn on again after a pause of 5 seconds then a long pause of 10 seconds and again, together with the LEDs on, the fan also turns

Re: fujitsu lifebook a555

thanks, do I have to write them both one after the other on the chip?

Not on the same chip... write the bios to the 8MB chip. I`m not sure if the KBC has an external chip to write to (and what size the chip could be,the 128KB file might need padding out) or if it needs programming through the keyboard connection. Just flash the bios for now.

Re: fujitsu lifebook a555

ok, I understand, it should have a flash for the kbc or you have to program it from the keyboard connector only that for this operation I imagine you need a special programmer and adapter flats for the keyboard connector, now I try the bios clean, thanks

Re: fujitsu lifebook a555

I tried but the result is as before, I also tried with another chip, the strange thing is that with the software of the ch341 on the verification it tells me that the chip does not correspond to the document and with neoprogrammer it tells me ok

because the ch341a software is poor.
