Chassis Intrusion Reset OS
Ran into a situation tonight where I activated CID (albeit purposefully :)). POST completed then WS 27 appeared but got stuck halfway through loading. The only way I would resolve the problem was to disconnect the CID cable, disable in BIOS then do a clean reinstall. Has anyone ever dealt with this before? This unit is an enterprise refurbished machine.
What does CID actually do when enabled? What's the hardware/BIOS? Are you sure the activation of that switch made Fedora stall? Did you change any other hardware, like video card?
