1)	Boot with "-c" and disable the serial ports until you are
	successfully installed.

2)	Get -stable, -current, or apply the patch in the FAQ to
	the sio.c file, and rebuild a kernel.

3)	Reenable the serial ports.

4)	Call Mach and complain that the IBM standard requires that
	they ignore port 2e8 unless you specifically enable the
	IBM-adapter-compatible video mode (like IBM does) because
	2e8 is the port for Com4:.
