NUC8 HDMI firmware

Hi,
Does anyone know where I can download the latest firmware?
This link is no longer valid:

BTW, how to update the firmware if HDMI port is not working?

Thanks for the reply.
There is no signal on the HDMI port, even using the HDMI-to-DVI converter.
My guess is that the LSPCON chip is broken.
