I have a home server running headless (i.e. without a monitor), using ssh for remote access.

This works fine most of the time, but I still need a graphics card and still need to drag out a monitor whenever I have to access BIOS, (re-)install the OS and similar.

I know that there are business servers that let you control everything remotely (over Ethernet), including power up and BIOS access.

Is this type of functionality available for "prosumer" class hardware? If so, where does it sit - should I look for motherboard support, a PCI-e card or an external device?

And does this type of functionality have a name, so I know what to google for?
