On a mobo I used to have there was a non functional 83 mhz option that was asynchronous I believe the reason it didn’t work was the chipset or mobo wasn’t able to go async. I suspect your no boot option may be that. Mine also would not boot. My understanding was it was because of the rest of the mobo, not the chip.

Many old boards could only run async with a Cyrix cpu, though occasionally it was just a VIO issue

What effect will replacing the ref crystal have? Does it have any implications beyond overclocking the PCI and AGP bus?

Ref crystal makes your floppy controller puke and legacy devices plus date and time.
