Sorry. I just assumed nobody would even care about this antique. Hope
no one is too annoyed by the self-ack.

no, because the Dell BIOS turns it completely off.

yes, I'm cloning what they do by watching IO with serialice. They did
not read it and or it in in this one case.

Going to have a long delay now while I convert to CAR. Also having a
