OS 9 in a PwrMac??

I need either guidance or told to simply forget it. Have a couple of Pwr mac's and a pwr book 1400 all w/ sonnet G3 cards. Got a unlicensed copy of OS 9.1 like this http://eshop.macsales.com/Catalog_Item.cfmID=5913&Item=APLOS91CD
But of course it says imac on it and I think that is what it means ... not just any old upgraded G3 ... I may as well have put a 9.2.2 CD in it..... Should I just blow it off or am I indeed doing something wrong??

OOPs

Sorry bout that ... It will allow me to boot fm the CDrom but the software installers dont work The message is " This software cannot run on your computer see documentation" so what the hey I goes to the Software installers/ system Software and try that installer... msg is " Install system software requires version 4,5,3 of the installer app." and " Please try opening the installer app. that is inthe same folder as this installer doc." Well I cant find nothin' like that!!! All that's in there is morsels, extras and installation tome... What do ya think?? Oh! There is "net boot disk image pieces" will that do me any good?? Thanks again for the help and or guidance... Marty
Just noticed the link don't work (versions are different so maybe that is key!!)

decided to put the disk image onto a cdrom (burned it) and boot fm that!!! Just exactly like ya took a HDD fm a imac and tossed it in a power pc .... very unhappy software... this disk obviously says imac on it for a reason.....Oh well ... who out there needs an imac disk set???? Or the heck w/ it as cheap as old imac's are I'll just get one .. hmmmm wonder what flavor (color) the "evil half" would like???? LOL Thanks for the replys and if anyone happens upon a "new" method pls keep us posted... Marty
