>Environment:

	Intel Atlantis MB with Video and Sound card on the motherboard.
	Pentium 133
	FreeBSD 2.1R

>Description:

The sio probes cause the screen to become blank. Other than that, the boot
process continues regularly and the system seems to work. But no
screen output is available.

>How-To-Repeat:

	Just boot the OS.
	Disable the sio probes and you see the screen output. Enable them,
	and the screen becomes blank at the first sio probe.
	
>Fix:
	
	Not available yet.
