Yup you did, and it didn't help my boot problem.
Yes, it was unrelated to your boot partition problem in the end, but I explained to you what those settings can do.
Anyway, I think that SCSI inquiry delay should be the one to increase to something around 15+ seconds. I am at work now and can't remember how exactly it is called. Try it. If you screw something up, holding ESC at boot will always take you to the CSPPC menu and you can return the settings to old.
