This requires extracting the firmware from a good motherboard and downloading it to this motherboard you have. The EEPROM connected to the EPF chip only holds the configuration file, not the firmware, the real firmware is only inside the chip.The BIOS isn't sure if it has that firmware, if it does it may be an IAP to upgrade the firmware via the LPC bus. I'm not familiar with 8051 core microcontrollers, so I can't analyze the existing firmware to see if it's upgradable.... -
A short found after raising the voltage will not burn through the printed circuit board, but it should not exceed the maximum voltage withstand of the chip. Sometimes the short location will be around a via hole and you can drill some through holes to fix the short, but I've only encountered two motherboards like this.Leave a comment:
