Hi,
can anybody write me how to setup PROM on Indy R4600 to tell
kernel the name of root device? 

I've seted up:
 setenv systempartition scsi(0)disk(2)rdisk(0)partition(8)
 setenv osloadpartition scsi(0)disk(2)rdisk(0)partition(0)
 setenv osloadfilename netbsd
 setenv osloadoptions auto
 setenv osloader boot

But in the boot process it stops and ask me for root device.

Thank you for your help,
--
Roman
