Even with a dead battery you should have seen console output. I would check the serial cable, p2 adapter and 712 console port jumpers first. You could try to boot directly from the eprom which holds the 197bbug(using the DIP switches) in case the 197bug has been flashed with custom firmware(never seen this, but who knows). You can remove the 297 expansion card as 197 has its own memory soldered on the back-side.
