Ok, I think I remember!
VERY IMORTANT BEFORE PROCEEDING!!!! Copy drag your os 9 HD alias to your os X hd alias. Took me about 15 min to copy it onto OSX.
When trying to get into OSX from OS9 you have to Hide the "finder" into a "finder folder" - make a "new folder" and name it: "Finder Folder" in the system folder.
Then, when you want to go into osX you have to go to apple menu/ open the control panlels/ startup disk..then stop - leave that window open without selecting anything.
Then go over to the OS 9 hd alais, navigate to the "finder" (you should see your newly made "finder folder" nearby) and drag the "finder" into the finder folder. Now you'll notice (if you backwards navigate) that your OS9 sys folder is "unblessed" (no smiley face on the folder)
then, go to the open startup window (remember I told you to leave it open! If you didn't you'll notice that you don't get the option to control panels, because you have no blessed sys folder.
Anyway..moving on...select to OSX drive as startup. It'll warn you startup is selected and that your computer maynot restart - don't fret...It'll restart, make a "bong" the restart again....don't worry about it, it'll come up in a min.
This will present you with OSX!!
Now, to get back (there may be another route) but this is what I do...restart from OSX into OS 9 on the OSX HD (the copied OS 9 that I warned you to do earlier)
Then, when that is up, go to the startup disk selection and select the OS 9 on the OS 9 HD. This is if you want to get to that particular OS 9 on the OS9 HD. I do, because I wasn't (and still not ) using OSX much so I'm still in my original OS9 on OS9HD... I also now regret not setting more gig space in my osX partition:
40 gig
os 9 - 30 gig
os X 6 or 8 gig...I now only have 1.25 gig left
Good luck...one other thing - make sure your cd drive is original (at least not a cdrw, some of the cdrw's won't boot)
*whew*
