When you say `blessed as the startup disc' do you mean that you've
ensured that the System Folder is blessed; or do you mean that you've
selected the disc (as in the actual disc in the drive) as the startup
device using the Startup Disc control panel?

What *does* happen when you start up?  Have you tried sabotaging your
usual boot disc by taking the System file out of the System Folder and
then un-blessing the System Folder?  Will it boot off the Jaz drive
then?  (and do make sure you've got some sort of working boot disc (CD
or floppy) handy before you do this).

Maybe the Jaz drive hasn't powered up enough by the time the PowerMac is
looking for a startup device?

(I've heard of trouble booting Mac Pluses off Zip drives because of
trouble with the non-standard SCSI port and the inability of the Mac
Plus to use the latest drivers, but never anything like this.)
