The HannStar J MV-4 substrate has been used by dozens of OEMs (e.g., ECS, Biostar, Jetway, and many white-label manufacturers) for low-cost Socket 478, LGA775, and early AM2 motherboards. Based on troubleshooting history, this marking is most commonly found on: hannstar j mv-4 94v-0 bios bin file

On some boards, shorting specific solder pads (often marked “CLR_CMOS” or “JCMOS1”) may work, but this depends on the exact revision.
The difficulty with the HannStar J MV-4 is that this board was used in several different laptop chassis. The ports and layout are generally the same, but different laptop models used this board with .
