So you say:
1) Sold pin on BIOS chip;
2) Turn windows on (i've read Dos is better, should i use it?);
3) Flash the original bios;
4) Turn off system.
5) unsold.
Am i right?
1) Solder wire between pin 1-8 on BIOS chip(suggest that you check your BIOS chip datasheet in case its a different chip, you need to turn CS high(to positive/VCC) in order to disable BIOS);
2) Turn windows on;
3) When windows finished booting, clip of the wire(now the BIOS will be enabled, but GPU will not read content from it)
3) Flash the original bios;
4) Turn off system.
5) unsold.
