Cancel Red Alert. (But still looking for info)

'Found info on the differences between new and old DS5K's ROM Monitor
and surmised that I needed something like:
>>boot -f rz(0,N,0)vmunix

where the N is the disk number.

I ended up splicing the DS2100 box's internal disks into my VS3100 
and using 'test 50' and 'show dev' to get the SCSI address of the 
DS's internal drives.

Anyway I got it booted (and think I probably want to add -a after vmunix)
and will be able to boot again, ... 

I would still like to get info on how to 'read' whats on the SCSI where, 
and how to set up the environment for autoboot ala the VS's that I run.

PS:  part of my problem was that my DS RRD is set on address 4, and so was
one of the internal disks.

Have a good weekend,
