Hi, a friend of me has a bunch of Macs, from that 97 G3 to a G5 1.8 SP, so I give him my Yosemite ´s Rage 128 (I replaced it with a Radeon 7000), and now he want to place it inside the G3 desktop, saw that G3 has a built in ATI Rage II, we put the Rage 128 into a PCI slot of course, then start and no screen :-/ The fact that the G3 desktop has built in video, could disable the option to enhance the GPU ? Have anyone replaced or upgraded a G3 desktop graphic card?

Any advice is welcome :-)

The onboard video usually requires an adapter in order to attach a VGA cable to a monitor, but the PCI video cards usually do not. Make sure the VGA cable is attached to the Video card without an adapter, and remove the adapter attached to the computer's onboard video outlet (having it attached can fool the computer into thinking that there is a monitor attached there). If that doesn't work, try zaooing the pram, holding down command-option-P-R at startup until you hear the chime 2 times. Still no video?
The old Powermac G3 Desktop I have is very particular about installing an OS X system, and a lttle less particular about running one, bit it absolutely refuses to run anything newer than 0S X 10.2.6, and gets all messed up soon after upgrading to 10.2.8. What system is installed?
Assume you have checked that the appropriate video drivers are installed?
Good Luck

After I installed a Radeon in my old BeigeG3, it would no longer show me the grey screen with the dark apple logo during the early stages of booting up. After a minute or so the screen would flick on and show the last bit of the os x startup progress bar before loading the finder. Perhaps it does work and you just didnt wait long enough to find out. Although the beige guys are very finicky with X so I wouldn't be surprised if something else is wrong.

Yes, onboard video has the Apple outlet, but the ATI 128 card needs the adapter in the reverse sense, that is, the monitor has the Apple port, not VGA port.

I did not try it really. Good suggestion.

I some Jaguar version, but the owner wnat to install Panther on it, go figure.
What about XPostFacto? (http://www.macupdate.com/info.php/id/7594)

It is needed really?, that is, my though was that Mac OS X just would recognize the new card since is a card that came with an Apple computer.

hum... hope that was the way, will also let it think some time about its new card :-)

Thank you very much for your advice.
