Multi OS Boot question...

Mac Metal Head
I use a B&W G3 at work for making images. I have 2 hard drives in it, the standard and then another on secondary slave that i use as the target, After i created this last image I installed it onto the 2nd hard drive. I can't get the thing to boot from the 2nd disk, if I select it from the startup disk it sits there with the questionmark folder deal then decides to boot off the othe disk. Holding option doesnt get me anywhere, so I assumed it is not supported on this Mac.

Any reasons it wont boot? does it need to be master?
 
One drive set to Master, one set to Slave. Both should boot.

How did you make the images?
Carbon Copy Cloner works very well to clone systems.
 
One is alone on the Primary IDE channel, the other is slave on the secondary. I used CCC, the thing that boggles me is that Startup Disk finds the one I want to boot from with the correct version and everything, when I select it, it fails to boot from it and falls back to the other.
 
I did an ASR, the option was grayed out, i assumed it would be bootable.

Heh, it's been a while since I have made an image, I cant remember how I did it last time.

To have a SLAVE you must have a MASTER on the same bus or channel. with two drives, one on each channel, they must be both set to MASTER

Ah yes. I hate to think of all the times I have assumed and my assumption was wrong. According to man asr in Terminal

man_asr said:
source and target can be /dev entries or volume mountpoints. By default,
asr will restore in place, and will not bless (see bless(8)) any folders.
If -erase is specified, any blessed folders on the source will also be
blessed on the target.
bless -info /Volumes/<vol>
will display current blessed folders for the given volume.

Yea the hard drive is slave to the CDROM... I replaced the ZIP drive with the hard drive so I didn't want to bother with changing jumper settings on the CDROM
 
hang on a second. you have one drive on a dedicated bus, and one sharing the Optical/Zip bus? i'd move the hdd to the other (HDD) bus. the optical/zip bus in G3/G4 towers has ALWAYS been severely crippled compared to the normal HDD bus. it doesn't need extra speed, cus the drives were never fast enough to need it.
 
I didn't have any extra IDE cables around, the one that it had only had one plug.

Just as an update, I put the drive alone on the primary channel and it worked fine.
 
What revision of B&W G3 is it? Some earlier models did not support adding a 2nd (slave) hard drive. Does the hard drive bracket on the bottom of the case look like it's set up for one or two hard drives?
