Attention: We do not recommend this product to individuals without basic hard drive knowledge, proper tools (such as a hot-air station), or technical skills. If you cannot find an electronics repair service to assist with the BIOS transfer, do not purchase this item. We are only responsible for providing a fully functional PCB.
