Lost YDL boot

[Harvey Ussery]

Thanks so much for reply, Greg. I will give this a try--it looks like it 
could work.

    "Then, the all important step that you may perhaps have forgotten, 
run /usr/sbin/ybin."

I did run ybin after reconfig'g /etc/yaboot, though it didn't seem to 
have much effect. I just issued it as a command:  ybin    --not as      
/usr/sbin/ybin
Think that might have been a problem?
