My question for the Slashdot audience is: Is there a good solution to allow me to login to this box if it cannot get on the network? I'm looking for solutions other than slapping a video card back in. In my case, I will have physical access to the machine.
A few caveats to make it interesting: This question is for plain old desktop/laptop systems, not network servers designed to run headless. Also, I am aware of the serial console, but even "old" machines may only have USB, and I have not seen any good documentation on how and if USB works as a substitute. Finally, if there is any way to access the BIOS settings without needing a video card that would be an extra bonus, but I'm satisfied with just local OS access starting from the GRUB prompt. I'm all ears for advice from any Slashdotters with these setups running.
