NOOOOOO!!!!!!!!!!!

[Richard]

What began as a simple upgrade to a Radeon 7000 Mac Edition cost my 8500 its life. I installed the System7Today ATi Drivers. I opened up the 8500 and installed the Radeon, closed it up, and started it up. No video. I figured I should have hit the CUDA button. I opened it up, and removed the motherboard, with much difficulty, and hit the CUDA button. In the process of removing it, like 10 plastic tabs snapped off from here and there. Even half the PCI card retainer snapped off. I ripped off the rest of it because it kept cutting me and was pointless anyway. It turned out I didn't even have to remove the motherboard to get to CUDA. I had ruined my 8500's inner case for nothing! I tried to put the 8500 back together but failed. I started it up naked, with all the necessary connections done. Still no video. Since I had the motherbaord out already, I tried removing all the VRAM for the built-in video, which apparently could force the video to be from a PCI card. Still no video! The system just refused to give video to the Radeon! This wouldn't be so bad if my 8500 was together! I don't even think I can get that brittle case back together again probably. I can't even slide the motherboard back in, much less put the power button back in and the outer case back on.

What can I do? :'(

Also, I tested the card. It works fine in my B&W G3 straightaway, so it is not the Radeon's fault.

Leave it unplugged with no PSU/PRAM battery on it. Those PowerManagers/Firmware chips get so confused sometimes, the only thing you can do is let them drain all the way. You probably crashed the PMU causing stuff not to work. I would do that. It has cured my 9500 board numerous times. Also, make sure the CPU is pushed all the way down into the slot. They will come on, but with no chime if the CPU doesn't seat all the way down. (I would try the CPU thing first rather than letting it sit as the first remedy step)

 

[Richard]

It has been bonging, and I can hear the HD spinning up and Mac OS starting, it just refuses to output video with the Radeon 7000. I just tried zapping the PRAM, but it didn't work. I will leave the battery out of the motherboard (which is removed from the 8500 at the moment as I could not get it back in) for the night.

This sounds like a problem I ran into with the Radeon 9200 in OS 8/9. It happened when I reset PRAM or significantly changed configurations. No video would come up and I never figured out why.

Try starting up and just let it run for a few minutes, that should be enough to complete the boot cycle. Then press the power key on the keyboard and hit return. This should shut it down. If that doesn't work, just turn off the power manually. Then turn things on again. You should get video.

If by chance that still doesn't work, go back to the built-in video or an older video card if you have one. If it then works, it's something with the 7000 that your system doesn't like.

 

[coius]

ah hah! i know what's happening!!!! And it's a common problem with external video cards (PCI Cards). This happened with a G3 and I figured out what's going on. OpenFirmware is not initializing the card. Hence no video. It's trying to use onboard video, because it doesn't consider the pci card.

I had to boot into the OS and get it setup, then reboot. After that, it would work. I just realized it!

Sorry bud, but to do this, you gotta get it into the system with onboard video. It's the only way to cure it.

^^interesting point there, I actually had the same sort of problem when I stuck a 128 in my 6400. No video, so I started up with the onboard to check all the drivers were installed and rebooted using the ATI card and it worked. I just figured it was 'one of those things' and never realized it was an openfirmware issue.

removed the motherboard / 10 plastic tabs snapped off / half the PCI card retainer snapped off. I ripped off the rest of it

You Are Doing It Wrong

Might I suggest you switch to decaf?

I think I may have blew up the 604e, B-note. :-x

 

[Rodus]

^^are you UK based? I have a spare 150 Mhz 604 cpu that I'd let go for a couple of quid.

 

[Richard]

I am in USA.

Double check to make sure all the connectors and cards especially the processor card are fully seated

If it doesn't output video to the Radeon, how about the built-in video?

Have you tried shift booting it? Sometimes there's compatibility problems with some of the Ati extensions.

 

[Richard]

I know I broke the 604e because I ran it without a fan without realizing it. [)] ]'> It got REALLY hot. And the built-in video did work when the CPU was alive. I will try getting the Radeon to work once I get a new CPU.

 

[Bolle]

you cant run those boards outside the enclosure... the board is grounded through the inner shielding via teh PSU anclosure.

If youre running it outside of its box you have to do this:

to get it worky.

normall theres a small springy thingy taht connects the ground layer on the mobo to the shield which connects to teh psu case.

 

[Richard]

The 8500 was upsidedown and the mobo was on the carpet, hanging out of the 8500. Because of this, the CPU got ultrahot and died. I am not sure what I was thinking using a motherboard on the carpet in the first place…

Here is a picture of the idiotic idea…

I know…

Anyway, I ordered a 500mhz G3 Crescendo/PCI. I wanted a faster CPU for what I intend to do with the 8500 anyway.

No, he's doing it ... hard to say correctly ... but many's the time I had blood on my hands when getting my ol' 8500 motherboard out.

The cure is simple ... simply take it apart again and again, until it slides out nice and sweet! I recommend 3 times in the morning before breakfast, and again in the evening.

 

[Bunsen]

Bah. You're not a real MLA soldier until you can field-strip and reassemble an 8100 at midnight, in a muddy foxhole, under heavy artillery fire.

You can fix all the little broken tabs with super glue. You have to really take your time though, and make sure you're gluing each piece in it's original place, you will have to look very closely at how it broke to make sure it fits perfectly together before gluing. Also wait at least an hour for the super glue to dry or it will be weak and get white residue all over the motherboard from evaporating.

Also refer to the service manual to help you, it explains exactly what to do. Most importantly, TAKE YOUR TIME and be patient. I think this could have all been prevented if you just took a deep breath and thought about it before digging in.

Put everything back together first and try again before buying any new parts. The processor may have overheated but it's possible that it will still work.
