I almost remember manually booting UNIX with arguments 30 years ago, but I don't have a clue how to do it with the self starting LINUX of today. Can you give me a kick start?

I also believe I will have the same problem again when I need to update ubuntu and/or EMC2. To avid this prolonged agony I would like to install simple Video cards that do the job for the foreseeable future With EMC2 and my processors.
