Powermac 7200/90/sonnet/ati/os8

[modplod]

I have been trying to fix up a 7200/90 I got at a yard sale with various extras I picked up cheap. I just installed OS8 then I installed a sonnet g3/400 pci upgrade card.....worked no problem.....the tried to install an ATI rage card and the computer would not boot properly. The rage card works without the sonnet card, just can't seem to make them work together.

The mac has 90 mb ram, 2x 500mb hard drives and has the vram slots filled.

Hoping someone can help.

My handful of different permutations of the Cresceno G3 have never given me a single problem . . . so . . . .hrrm . . .

Clarification may help, have you differentiated between:

a physical presence conflict at the hardware level . . .

a driver conflict with both cards present using the Extensions Manager . . .

an extensions load order conflict . . .

I'm half asleep . . . so that's all I can think of offhand. :?:

I have some experience with mac osx but virtually none with os8.....so in answer to your question.......don't know.....sorry

Am I beyond help?

Nope, not at all!

Around these parts: the only stupid question is the one that doesn't get asked!

Have you installed the drivers for the Sonnet G3 Card?

Have you determined that it is working correctly?

By "works," do you mean that you can choose amongst all "availabe" resolutions from the VidCard or that it gives you 640 x 480 just fine without even loading the drivers for it?

Does the Computer boot:

When either card is installed alone and both of the card's drivers are correctly installed and activated at the same time under the "Extensions Manager" Control Panel?

Try hooking up two monitors for your troubleshooting. The system might be trying to display an error dialog on the built-in graphics card.

I can't remember the last time I used an ATI Rage. Does it flip in immediately when the Mac is switched on, or is it enabled by a system software extension?

It will work without drivers, but you need the right driver for your OS version to enable the cache. Without the cache it will be slower than it's fully capable of.

Installing drivers for the video card is probably a good idea too.

BTW, are you using MacOS 8.0 or 8.1? 8.1 is a free upgrade, and recommended.

A while ago I set up the same configuration of hardware with an additional Fast Easternet card. As of the Sonnet driver software does not work with any of the Mac OS 9 versions, the machine got a fresh install of 8.6, upgraded manually with any extension and control panel from 9.x that would work, including ATI driver software. The machine runs properly as a productive system still.
