Yury,

Wow! I've never heard of Intel AMT (vPro).  I did some quick googling.  I'll investigate more as I manage clients' computers remotely using Remote Desktop, VNC and ssh.  Thanks for the new information.

That would take care of Ed's original issue, but I don't see how you could remotely view the BIOS settings as it's not possible to have the VNC Server running when you boot into the BIOS screen. What do you mean, "this HDMI display emulator to allow me to remotely view the BIOS screen." How are you doing that?
