Installing OSX Tiger on upgraded Bondi

I have an original 1998 iMac G3 Bondi with upgraded CPU card (366MHz G4 thanks to dosdude) and DVD-ROM/CD-RW drive. Trying to install OSX Tiger with XPostFacto, but for some reason it gives me a 🚫 sign after reboot. Weird thing is it will boot a Tiger DVD or CD with the normal startup key method.

Couple of things to try

- Reset NVRAM, PRAM before booting, CUDA reset on motherboard
- Boot in verbose mode to see errors (hold down command + V at startup)
- Do the Open Firmware hack to misreport your CPU speed at 866Mhz +
- Check iMac last firmware is applied - 4.1.9

You also need to install Tiger on the first partition < 8GB (anything above that format as second partition); you might also have luck installing Tiger using another Mac and moving the hard disk over to your iMac G3.

Verbose mode didn't work for some reason. Firmware 4.1.9 is for the slot-loading models, installer for the 1.2 firmware says it's already updated. I'll look into that OF hack but I suspect the problem was that I was trying to install on the second partition. Maybe I should just do a clean install of 10.3 and upgrade from that instead of OS 9.

Yeah, I'd try a fresh reformat under OS 9.1. Both OSes can coexist on the same partition, but ideally have two separate. I wouldn't do a cross upgrade from 10.3 - you're adding too much pain!
