![]() I received several warnings regarding that the device ID did not match (currently 0322 but I was flashing 0321). Where NewRom.rom is the filename of the new ROM you wish to image on your floppy. Secondly I flashed the card with this command: This is the oldest AGP card to support both Core Image and Core Animation! To flash it with the new ROM image obtained from The Mac Elite (link below), I had to use a PC with an old Windows 98 boot disk and a floppy containing the nvflash utility and the new ROM image.įirst I backed up the current ROM using this command: I used a PC ASUS 9520/TD card which has the nVidia FX 5200 chipset. To do this I simply taped over pins 3 & 11 with scotch tape and viola! Therefore as in my case when upgrading the video card with a 8x AGP card pins 3 & 11 need to be disabled. To accomplish this Apple added an extra slot at the front of the AGP card and also used pins 3 & 11 on the backside of the AGP card which at that time was not being used. At this time Apple was using the Apple Display Connector which provided power through the AGP card removing the need for an additional power cable. It is possible to upgrade the video card in most G4 AGP equipped Macs with certain PC based AGP cards.Īt the very least you will need to flash the firmware on the card with a compatible Mac version. Type in the following (press Return after each line):ĭev 867000000 encode-int " clock-frequency" propertyīasically this fakes out the installer into thinking that the system is running at 867MHz until the next reboot! See the link below for further details. Make sure you have your Leopard DVD loaded in the drive.Ģ. Startup your computer to Open Firmware (press Command+Option+P+R immedietely after startup bong). After doing some reading performance is noticably better using 10.4 "Tiger" but I wanted Time Machine and some of the other features Leopard has to offer. ![]() Mac OS 10.5 "Leopard" is officially not supported on anything less that a 867MHz G4 and this Quicksilver is 800MHz. It only had a CD burner in it so I replaced that with a proper DVD Burner and maxed out the RAM at 1.5GB. It had some Sharpie on it so I took care of that with some Rubbing Alcohol. I took it home, fired it up and it worked perfectly (a little dusty though). I can take old junk to be recycled and come home with more! This time I was dropping off a bunch of gutted PC's from work and picked up a 800MHz Quicksilver. I really like the electronics recycling program here.
