Tiger/OS9.2 installation and Booting issues among multiple HD's

Question

G4 PCI, (thats bootable in 9, must be booted in 9 to use an essential business app). It has 2 HD's: an 80 G ata for OS9 & apps, & OSX (from Jag - Tiger, w/minimal apps&files. I later added a SATA 320G driven by a SIIG, pci card. The 320G became the main Tiger,X Apps & files HD, the smaller one for OS9 only, & Tiger emergency boot. The 80G died, but I was able to clone everything on it to a 10G ATA, that was then installed in the G4 so I could run the business app.
I also cloned the dying ATA HD to an empty 114G partition on the Large SATA HD. The idea was to transfer the os9 & Business app to a large partition bec it needed normal space. I couldn't get the G4 to boot in 9 from that partition, though it was a clone of the ATA HD??
**1. The OSX "Startup Disk CP" in the Large SATA HD, sees both Tigers and Both 9's in both HD's. I can restart directly into the Small ATA HD's X or 9. It will not boot into its own 9, though the CP sees it, and allows me to choose it. Itwill auto restarts back in its X, after a blank grey screen while it trys to make sense of whatever it sees in the 9 partition. This 9 is a clone of the ATA HD's perfectly working 9.
**2.When happilyrunnibg in the Small ATA's 9, its "Startup Disk CP" only sees its own X & 9, it doesn't see the SATA HD at all....To get back to the Large HD X, I must first reboot into the Small HD's X, then its Startup Disk CP sees the Large SATA's X & 9. I can then reboot into the Large X, but again not into the Large 9 (same deal as above).
**3.I tried to clone the ATA Disk (working 9&X) to a new external USB HD's 100G partition. It took forever. The SATA CP saw both in the Ext HD,but wouldn't boot in either in either. The ATA saw both but wouldn't boot.Scarey, very nasty freeze/crash, that refused to find any ogood OS.I
**Apple-C, with the 9 CD didn't work... grey dead screen, so I couldn't install a new 9 on the SATA, if it could be found?. I had to use the X disk CP to find a working OS. I Don't want to tell you how many hours of crash restarts with & without the Tiger Disk and repairs I went thru.
** How can I install 9 & its apps, to the large SATA partition?**Why didn't the cloned 9 work on the SATA?** Why does the ATA Startup Disk CP, not see the SATA?**Why do both HD's Startup CP see the EXT usb's 9 & X, allow you to choose them, when they are not bootable? Why are they not bootable? Help!Help!Help! Thanks so much. Totally exhausted! I know the easy answer is getting a new 80G ata and cloning the working 10G to that one, but why won't the SATA work???

Answer 1

Maybe the drive is using a GUID partition table. Tiger can read and write GUID drives, but PPC Macs can't boot from them. Select the drive (all the way at the left, not the volume indented below it) in Disk Utility, and look at the bottom-right of the window for "Partition Map Scheme". You need "Apple Partition Map" for it to be bootable by a PPC Mac. This is selectable via the "Options" button in Disk Utility's "Partition" tab.
Also, for OS 9 to boot, you have to chose the option to install OS 9 drivers when you initialize the drive.
