This afternoon I tried every driver I could find, even those for the Mac Mini G4, and the same thing happens with all of them: ATI Graphic Accelerator appears crossed out, and the desktop is left without icons. If the IDs for the 8500 and 9100 are the same, I assume there's nothing to change in...

Okay, thanks a lot!!! I've ruled out any other possible symptoms of the problem. I'll keep investigating! :)

Hi, let me revive this post. Shortly after those attempts, the PM7600 stopped booting. When I press the button, the LED lights up, but no chime, no image, or anything. If I press the button again, it immediately shuts off. It's been sitting idle for a long time waiting to recap the PSU, because...

Thanks for the tip. I'll look into it, but I don't know if I'll be able to; I've never been very good at modifying drivers. From my ignorance, I understand that the 9100's ID is in the hardware; it's not something you can add to the ROM, right? Reviewing the photos I added earlier, both...

Thank you all very much for the ideas. I've run several tests and think I've found the problem, but I can't find a solution. First, I compared the Radeon 8500 64MB with the Radeon 9100 128MB using xbench, and both have similar results; one has more memory, but the other uses it faster. I think...

The Ati Displays control pannel?

:) Ok, I'll try Quake 3, I've never played it, but I was referring to some software that allows me to verify that it works correctly, OpenGL, and other things.

Thanks for your answers, I'll continue testing as you suggest. Doing a Google search, I found this link from another user with a similar result: https://aquamac.proboards.com/thread/1485/radeon-9100-128-mb-vram What software can I use under Sorbet to test graphics performance? I could compare...

Hi, I recently found this used 128MB Radeon 9100 for a good price and decided to flash it for Mac: For flashing, as I don't have a PC, I use a TLL866 programmer and I have a few 25P10 EEPROMs to replace the original 25P05, which I have used with other graphics cards (7000PCI, Radeon...

Yes, I know how to do it, I have done several G4 CPU swaps.

This afternoon, I had a little time, and I reflowed the CPUs. But the result is strange. Now the GE won't power on. Sometimes the red LED on the motherboard lights up for less than a second, then turns off again. No matter how hard I try, it won't power on. If I put in another CPU card, it...

Perfect, thanks. From what I understand, your patcher didn't remove anything from the original patcher; it's still valid for the 7447 and 7448, right? You only added the new G3s. This way I can make a boot CD and save it as UNIVERSAL. Thank you for the work you have all done; it's a shame I...

No había visto esta foto, hiciste un intercalador. Eres brillante. Ese es mi problema. :)

Although I'm pretty decent at electronics, messing with firmware is difficult if I have to type commands. I don't like doing it without understanding what I'm doing. The Newertech patcher I've used on some G4s has been a Newertech BootCD. I boot the G4 by pressing the programming button, and...

Okay, it's a good experiment to run, but the 750FX's BGA pattern would be different from the G3 installed in an iMac; that has a 360 BGA like a G4 PPC7400. Regarding the firmware, is the patcher joevt posted installed the same way as a PowerLogix or NewerTech patcher?

Sorry, I have a G3 750FX.

How cool! So, could the same swap be performed on an iMac G3 tray? I have a 750GX 900MHz processor on a faulty iBook G3 motherboard.

Thanks for the suggestions. I've performed the tests you suggested. I've cleaned thoroughly, tried pressing the 300-pin connector, the USB has power but no video, I've removed the EEPROM without success, and then put it back in. I performed another test, tried it on another GE that works fine...

I measured the Vcore and it's at 2.1v, which would be correct. I turned it on without a heatsink, and both processors get very hot, but it won't boot. The power LED is still off and there's no chime. I've noticed that the PCB is bulging downwards, I imagine from having the heatsink on it for so...
