How do you run Leopard on your unsupported G4?

You just need one of those super neat Sonnet cards with USB 2, FireWire, and IDE all on the same card :D
Behold:

USB2.0+FireWire 400+IDE+SATA
Yes, that SIL3112 is flashable. The IDE port is actually a bridged SATA port.

hah thats cool
I have seen those in Dual SATA form, but not one with one of the ports bridged to PATA

I saw one where the guy replaced the EEPROM so he could flash the Firmtek Firmware onto the card, its pretty much the holy grail of Macintosh PCI expansion cards

(the Firmtek firmware meant the SATA ports worked in OS 9 etc :) )

finding the EEPROMs is pretty easy its soldering them on that's out of most people's league sadly

(there's also a resistor you have to change on the board IIRC which sets the supply voltage to the EEPROM)

This is the issue I'm facing with this card, I'm not really confident enough on my SMD rework skills to change the EEPROM.
Plus I don't know where the voltage selection resistor is, if there's one at all. Though if it's just a question of feeding the proper VCC to the chip, I guess I could run a bodge wire and steal it from some regulator.

All LeopardAssist does is fake a higher CPU speed to pass the install check. Nothing more.

Where are you getting your information?
It would be interesting to run Leopard on a 350mhz Powermac G4 if even possible.

I have this machine as prepared as I can be in terms of hardware. It already runs Tiger. I have a PCI IDE card attached to two large IDE drives, one SSD and one HDD. And there is a 20 GB partition sitting empty, just in case I can get it done! The RAM is maxed out -- 8x128MB, all matched.

One of the PCI slots has a Radeon 9200. The third PCI slot has a combination FW/USB 2.0 card.

Tiger runs, well... it runs, not horribly. I have slot envy for a 9600. :)

I don't expect Leopard to run *well* on this machine, but the challenge is to do it at all.
Next challenge, run Leopard on a stock 350mhz PMG4 (or any stock G4 from the last century) with ram maxed out.

Not exactly a challenge-it has been done.

The 350mhz Sawtooth is better since the Leo is straight forward and it can take more RAM(2gb vs. 1gb). A Yikes! is a bit more difficult since you need the platform support kexts from the WWDC 2006 preview and also can only max it at 1gb of RAM.
 
somewhere I have a picture of my Sawtooth with 2GB of RAM running Leopard with a Radeon 9800 Pro but its stock 450mhz CPU still :)

That 9800 deserves to run Leopard again. You’d probably cry knowing that it’s current installation is Jaguar.

Between the 1.2 giga and the 9800, it should make a great Leo box.

Since the conversation seems to have drifted to "Running Leopard on Macs from the last century":

This might be a bit far fetched, but is there a way to get Quartz Extreme working on a PCI card under Leopard? I have a flashed Radeon 9250 in a beige G3, and I just can't get Leopard to use it properly at all. VLC won't play videos, for example. PCI Extreme worked great for Tiger, but not so much for Leopard.

I think @LightBulbFun would be the one to ask there.
I stuck a PCI Geforce FX 5200 into my B&W G4 and Leopard uses it just fine.
