Alright my friend built a PC and paired a B150 motherboard with a kaby lake i3 7100 CPU and when he tries booting the PC everything works except the display. We know this is a bios issue because I used my old motherboard and CPU with his PSU and same GPU and the display worked. How do we manually update his bios to the latest version with no display? Is there a way or does he need to buy a new motherboard because I heard B150 supports kaby lake with an update.
