Yeah, XPostFacto is just one of those products that sometimes takes a bit of mind twisting to figure out. Personally, my first use of it sorta was through BootX of all things to cram Linux on my old macs. Then the XPostFacto that used BootX to get things going.. It's been a while for sure, but once figured out it's very powerful and handy to have around.
My last use of it was to get OSX 10.4 on a Beige G3 Desktop with the non universal 1Gig G4 Sonnet in it... I REALLY REALLY miss that machine now. But cash was needed and out the door to a friend in Mexico it went.
So basically, yes, format your drive if you only have one drive to put the OSX partition in the first 7.9 (8 gig) of the drive max, and then say a 400 meg OS 9 partition anywhere up to the 128 Gig mark if you have one that big.
IF you need to go to a different hd for OS 9, just configure XPostFacto to use the right helper partion/drive.
The most confusing part to teach the guy that bought my machine was how to properly update the OS when XPostFacto was installed. Syncing up is very necessary I've found.
Good luck,
