How do I enable on board video with my beige g3?

#1 Thu, 5 Feb 2009 - 04:01 68kMLA

How do I do it? I had a radeon in it and now I put it in my g4 mac pro. Now I want to put OS 9 on this beige g3 but am unsure how to get the on board video to enable itself.....I have tried it with an adapter on a vga lcd, and an old apple monitor with its own (adb? is it) plug thing and both havent work thus far.

Well, if you're trying to use an old RGB monitor like the one for the IIGS it won't work, it has less pins even though the connector is the same. I'm not sure why a VGA monitor won't work as long as you have the right adapter though. I have the beige g3 tower I just picked up connected to a 14" Apple color plus display using on board video with no problems. Maybe something got jarred loose when you took the card out. Try reseating any cards, ram etc and see if that helps.

Some of those adapters have a bucket load of slider pins and the correct settings can be a real pain to get right, aer you sure it's configured correctly. Serously, I'd look into getting a PCI GPU, you can pick up an ATI 128 for next to nothing and it's far quicker then the onboard graphics.

Make sure the AV card is seated properly in the PERCH socket. It often seems like it is when it isn't. Did you get a startup chime?

Did someone take out the memory simm,its pugs in right in front of the ZIF.

Doesn't matter - there's 2MB onboard even without the optional 4MB DIMM

The very first beige G3 I had would not lite up the screen(VGA) with out

the 4mb stick under OS9. Honest...I had to buy one to get the machine to work.

Lets see im getting back to working on it and yes it does bong. I have no idea what the AV card is or what a PERCH socket is guys

Well if it bongs, the AV/PERCH card is installed correctly. The AV card is the one that has the sound in/out ports on it, that is installed in a black slot (PERCH) next to the PCI slots.

And only under OS 9? Weird. If it was under both I would say it was a fault with the onboard VRAM

The Beige series should have 2MB of VRAM built in and a slot for 4MB more to get to 6MB total. I don't think video works at all if the built in 2mb is bad, all the extra RAM does is allow for extra color depth.

Thanks guys I reseated the ram, the av card, and reinstalled mac is 9 (with my g4s radeon) and updated it to 9.2.2. Then I took out the gpu and the onboard video works great!!! :-D thanks again guys you are the masters!
