Possible SCSI address conflicts

[Doug Hardie]

FreeBSD 5.3-P5 with  device          atapicam in the kernel.

 From dmesg.boot:

It looks like there is a scsi conflict.  Both da0 and cd0 have the bus 
numbers.  I won't be back on site till next Friday to try the drive.  
Is this an issue?  Other than changing jumpers on the drives is there a 
way to resolve it if needed?
