Hi, a quick question. At first glance, they seem to have the same motherboard connector. I have an iMac G3 tray with a failing CPU card, and I could get one from PB G3 Wallstreet. Has anyone tried it? I know the fault is the CPU card because I put one in from another iMac I have, and it works then.

You can apply the COMBO update for the version you already have installed. I have done this in the past to fix problems. It is not necessary to update to a higher version.

I think it'll work for you on QuickSilver. I cloned the same OS9 and Sorbet Leopard installation from a GE to a QS, and it works. If you have a chance to test the computer first, just plug in your hard drive and hit the button.

Thanks @DarthNvader, I'll try to see what's going on. I don't know if it'll be able to detect the error. I don't know if it has any influence, but the Mac Mini extensions I had saved in a folder were 14 extensions, and the 9250 extensions were 16 extensions. I don't know if those two additional...

Hi, today I flashed a Radeon 9250LE with the driver from this site, and the same thing was happening to me as with the 9100: "ATI Graphics Accelerator" appears crossed out upon startup. However, I found these drivers on my HDD, which I had saved for a while, and they made the graphics card work...

good job! thanks!

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.
