The Daystar Genesis MP has code in Linux to bring up the additional CPUs. You take that code and make a PE for OS X and the 604s will run natively in Tiger.

Look at the full Picture... It's Qemu emulating a Sawtooth running Tiger with 4 fully functioning 604e CPUs. The GPIO used for the G4's and the MPIC fully supported 4 CPUs, it's just no production logic board ever had an extra 300 Pin CPU socket and the traces needed to tie that together. The...

it's not that it won't work... We'd just need to look at how Linux kickstarts the dual and quad 604s and use that to write a PE kernel extension for OS X to start the other CPUs. If I remember correct Daystar had a kernel extension that allowed 10.0 to work with the Duals, but 10.1 broke it...

The thing is what I changed for the R9200 from the iBook G4/eMac G4/Mac Mini G4 was the device ID in the drivers and added an 'ndrv' I took from OS X into a Mac OS style driver. None of this can be done for the R9100, because the 'ndrv' is already loaded and it has the same device ID as the...

You'll need another XPC100 for the iMac. I'm kind of waiting on you results before I do the swap on my Beige, I was really hoping I could just replace the XPC66 with the 100MHz part and clock chip the PCI to 66MHz but your RAM clocks not syncing with only 38MHz PCI let's me know that can't...

The MPC932 isn't pin compatible with the SC608 so I not sure is't any use to the Beige?

If you just need one of the daughter cards with the CPU and all, let me know, I have an extra.

It's been so many years since Joe worked on this. Back in the day I had a 9100 PCI in my PM8600 but I can't recall if it ever worked with the ATI Extensions for OS 9.

That tells us the 'ndrv' in ROM is working. Sadly I can't say what the issue is, the drivers should match by Device ID and the 'ndrv' is loaded and woking. By all I know about ATI cards and OS 9 they should be loading....

when you boot OS 9 without the ATI extensions can you change the screen resolution?

Not seeing anything that jumps out at me, as we already know the Device ID is the same and that is what I hacked in the OS 9 drivers to get the ATI extensions to load for the Radeon 9200 in the Mac mini G4/eMac G4/iBook G4. The only difference I see that maybe the issue you could do something...

ioreg -l -w 0 -n <DeviceName>

Did any version of the ATI Graphics Accelerator load? Normally when you get these desktop hangs in OS 9 with an ATI card the ATI Graphics Accelerator which handles 2D graphics acceleration is the offending extension. If your card has the same device ID as the Radeon 8500 you should not need...

I ordered one of these cards and it took the slow boat from China, but I have it now. So should we try and do away with the 'ndrv' and just load the SIM?

It boots, you just get no chime.

To add to it, the GeForce 6200 PCI lists as 66MHz "Capable", but runs the PCI-X slots in my G5 Dual 2.0GHz in 33MHz mode. So setting 0x20 in the PCI Status Register may just mean it will work @33 MHz when it detects a 66MHz slot? So it's "Compatible" and doesn't seem to be "Capable", but I've...

If you install Developer Tools there is a USB Prober application that will likely give a lot more info....

Great writeup, you went above and beyond with the old articles from magazines. We thought we really did something when we got 256MB of VRAM working flashing nVidia cards. At the time there were about two games that took advantage of more than 128MB. 768k was something in the late '80's. If you...

Well see, if it's the box you are in love with, why not expand what is inside the box to maximize speed and functionality? When 3D printers get just a little bigger for the home users, we'll get new plastics for our boxes. The PowerMacs are never going to get faster once you run out of...

A more elegant solution, and a more realistic one, is upgrading the 6500 with an Arm64 based logic board. Emulation of PPC has come a long way, my M2 MacBook runs the Mac OS/X PPC versions just fine, and I have even used PCI Passthrough for PCI/PCI-X cards in QemuPPC. As of this time...
