Today I remembered I had the original EEPROM and dumped its contents. Can help us solve the problem? I can read Radeon 8500 in the first few lines, but I can't decipher much more.

Well, I haven't looked at that schematic, but I've been comparing the datasheets and looking at the notes over the last few weeks, and from what it says there, the connection should be like this on the 744x: A[0:3] pulldown to GND A[4:35] -> A[0:31] 7410 AP[0] pullup OVdd AP[1:4] -> AP[0:3]...

Yes, I have unsoldered one and it is 1.27mm, 10x30, confirmed.

Yes, I had a 9100 on a GE, but I think it was 64MB, and maybe I wasn't using OS9 back then. We've tried at least. Thanks for your effort.

Perfect! Thank you so much!!! Even the datasheet!!! :)

Hello, what's the name of this G4 processor connector? Is it sold in any stores? Does the connector have a datasheet? Thanks

Unfortunately, I don't have an oscilloscope, so I don't know if I'd be able to locate a fault using that method. Yesterday, they lent me another CPU to test, but it doesn't work either. The fault must be in the motherboard; it will be complicated.

I've continued trying other drivers, with no changes. I've tried booting without the 8500 extension, and although the ATI graphics accelerator is still blocked, this time the desktop loads, but without 3D acceleration. Perhaps the 8500 extension is half-finished at 64MB? I finally tried...

Hi, this week is all about graphics... Along with an FX6200 that I managed to flash, I received a Dell GeForce4 MX440 64MB AGP x4/x8. Link According to the chip and memory specs, I should use a 270/200MHz ROM. Since it's AGP x4/x8, I covered pins 3 and 11. If I didn't, the Mac wouldn't...

Okay, @DarthNvader, I really appreciate your help. I don't know what could be causing ATI Graphics Accelerator to not load. Do you know the first version of the drivers for the 8500? I don't know if they came stock with some OS9 or with an installer. As an idea, I'd like to try others. Thanks.

Hi @DarthNvader I removed the ATI extensions, rebooted with the 9100, and yes, I can change the resolution.

I just tried moving the CPU to one side and then the other, and it doesn't work. I've also cleaned the CPU slot. No improvement.

Thanks @DarthNvader . This dump is for the same G4 GE. I dumped the 8500 first, then replaced it with the 9100 and ran the other dump. So I understand it's not something that can be modified in the ROM, but rather the drivers. I appreciate the help; these steps are beyond my knowledge.

Thanks for the replies. I've reset CUDA several times, tried with and without a battery... And I've removed and reinstalled the CPU several times, always with the same result. It's a shame I don't have another spare CPU to test.

Hi, thanks @DarthNvader for the instructions. I'm not sure I did it right. I don't think I typed it correctly in DeviceName because it looks like a full dump. But the two files have different weights just by changing the graph, so I assume all the information will be there.

Has anything similar happened to anyone with this model?

Quicksilver 2001 Exact, it's here.

That's right, none of the ATI Graphics Accelerator programs I've tried have load; they all appear crossed out. How can I dump .properties using the ioreg command line tool in OS X? Thanks.

Hi, although I already mentioned something in this thread, I was only asking how to adapt a SCSI disk that was not from a Mac. https://68kmla.org/bb/index.php?threads/hd-scsi-for-powermac-7600.46081/ Shortly after those tests, I decided to add a SIL3112 SATA PCI card, a 160GB 3.5" SATA HDD...

Yes, but if you look at my photos, they both have ID 514c. I can't change it to the same number. What should I put? On which driver? What software allows me to do this?
