I had the garbled console data problem once before. I went through slowly
and methodically starting with 8N1 through all the different baud rates that
Hyperterm would allow. I finally found the right setting at 1200 bps.
Other than that, I know of no way to clear the NVRAM although I'd suppose if
you knew where the NVRAM chip was on the board and which pin was the erase
pin, you could apply 5 volts to it to erase it. Someone might have a
databook that shows that pinout if you can locate the chip on the board.
Oh, the other solution might be attaching a console cable to the AUX port
(but I guess you don't know the enable password, which is probably the point
of all this, right?)
This is good CCIE practice for you although I suspect you already ran out of
time in the lab troubleshooting section (oops)
