All off? I think that's right. Table below from the reference says that's "19200 boot sequence operation mode". Unless you're trying to bootstrap FLOPPY, I think that's the right mode.For injecting FLOPPY into your laptop at 9600 bps, you want all ON. For operation mode (normal TPDD behavior) at 19200bps, all OFF.
The switch was indeed dusty or dirty, as I flipped it back and forth a bunch of times, and then all started working.
