also tried to flash bios with this https://vinafix.vn/threads/hp-compaq-presario-cq42-g42-quanta-ax1-dis-uma.7993/...
the machine came with display driver crash during windows startup. Graphics chip found to be culprit. In the absence of good quality replacement chip, we decided to convert this machine to UMA.
The Discrete graphics X2600 is mounted on separate board.
