GeForce 9600M GT and how restore from a BIOS flash failure? - 2009/12/19 12:10
Hi there, I got an Acer 7520g notebook which I did upgrade one year ago with a GeForce 9600M GT MXM module which has 512MB of GDDR3 memory. As many of us know this lappy BIOS has no support for such a card, this is going to manifest with an ugly and 30 secs long post at boot time stating to update motherboards BIOS in order to let the card work as needed. One year ago I did the performance table modification to my GeForce 9600M card in order to let it work at full speed and worked great...no way however to remove the 30 secs error message at boot time.
So recently I did something I should not have done. I flashed the card with a GeForce 9700M BIOS out of curiosity and the result now is that I have a blank screen whenever I switch on my notebook. I was tired of the 30 secs message and nothing helped me to hack the motherboard BIOS in order to skip such a trap. Before doing that desperade action I tried to uncompress BIOS modules, this however did not give me any chance to understand which module was the one to hack...yep..telling the truth I was not able to extract modules at all...no thyrd party software worked during this task.
Now apart from the fact I will never buy again a computer equipped with a Phoenix BIOS I am in a bad situation. I tried yesterday the tweezer method, the one which involves shortdutting pin 1 and 4 of the firmware to force the BIOS flashing with a black screen but my USB flash drive is not recognized and no activity is coming out of my notebook with those two pins shorted. So guys what do I have to do? Should I desolder the firmware chip and to flash it with my firmware programmer? Many thanks.
