As I understood it, those are referred to as 'lights-out' setups.  When
I first started seeing them on the market, they were add-in PCI boards
that had dongles that fed into the PS/2 and USB ports and they had
their own NICs on them.  The idea was that you could have a seperate
management network and hit those ports with a web browser and have near
full control of the system, even power them on, have full access the the
BIOS bits, interrupt boot sequences, etc, just as if you were at the
physical keyboard.

The first ones I saw were from Compaq, cira 1999/2000, they even had a
bit where you could upload a floppy image and have the system boot from
