automatic script on boot

hi everyone,

How can I place a simple sript (bash script) on a Zenworks 7 boot Cd? I
want this script to be automaticaly executed on boot, after the setting.txt
(I think). I have tried to put some commands at the end of settings.txt
but no effect.

this script will create automatic Alias for IMG commands, so this way, I
could only type GX260 or DB915 and image will be restored faster. Or
someone have another idea?

thanks!
