I've heard there's a company working on "graphics adapter" that has a serial port and somehow grabs the keyboard as well. It's supposed to allow for a "real" serial boot, allowing you to go into the bios setup remotely if you need to. I've also toyed around with a few of the cards in a USR Total Control Hub. Both cards have 486's on them, and allow you to enter bios setup off the serial port when you flip some DIP switches. I guess this is a custom BIOS they had built, but I'm curious why no one sells a BIOS eprom you can plug into a normal motherboard to do the same thing...
