I order eeprom reader/writer adapter Minpro100 For the time being, in a few days comes the second bios-chip from the asrock, I was suggested to make a save of bios, but of the total, but I do not know how to do it.You can buy a eeprom reader/writer adapter Minpro100 and some W25Q128FIQ chips to wtire a origenal BIOS in that for spare.
My MOD BIOS all had been test，if you not sure your CPU can work -70mv，you can use the -50mv one.
It would be interesting how to make a total and professional rescue
I have to learn with the eeprom to rewrite the bios, if it can on another original from my asrock, let's say it would be damage
I think for the first time to use the old dufus method, with sticks on the stick, to find out what suits the board and processor.
Then set me up at the best voltage and write it
I can handle a bios backup chip for now, if that's the case I'm buying on ebay
