I am running NetBSD/sparc 1.2 on a Sun 4/110.  I have just attempted 
to get an old Sun 3 shoebox going on the system (ESDI drive, MT21 
ESDI to SCSI board, 60M tape) without much luck.

I am getting the following error message on bootup:

sw0: data phase error                                                 
sw0: aborting, but phase=DATA_OUT (reset)                    
sw0: reset SCSI bus for TID=0 LUN=0                 

Can somebody perhaps explain what this means?  If I disconnect all 
devices (ie removing the cable from the MT21 board), it doesn't give 
any errors.  This shoebox has worked with NetBSD/sparc in the past...

Any assistance is appreciated...

Thanks.

Mike.
