Well, it's a well-known bug...

It seems that:
Some AMD motherboards will not boot the 2.2.2 floppies, while yet other
machines (I happeed to run across DEC Ventirus FXs) won't boot later
2.2-RELENG boot floppies. The cause for all this is still unknown. The
best cure available at the moment is to use the older floppy to install
the newer version (use the options section to change the name of the
distribution). You may have to do a little fixing afterwards, but once
you get the correct version installed you can run sysinstall and do most
things.
