To fix it if it's broken: Boot back into OS 9 by holding down Option at boot, start up XPF, hit the Options button, uncheck the "Enable L2/元 Cache" option, close Options, choose the X partition, hit Restart.Ģ) The Sonnet way. When the profiler comes up, it should list cache under the CPU type and such. If you do boot without the kernel panic, the way to tell if cache is enabled is to go to About This Mac under the Apple menu and click More Info. This will most likely result in a kernel panic at startup, but it may work for you. Then make sure "Enable L2/元 Cache" is checked, close the Options dialog, and hit Reboot. Here are the three possibilities, followed by how to fix it if your machine breaks.ġ) The easy way. The software supplied by different CPU upgrade manufacturers will work on other companies upgrades, so even if you have a Powerlogix upgrade, the Sonnet solution may work best for you. Amazing what 512 KB or 1 MB can do, huh? There are three methods of fixing this, and from everything I've read, it's kind of a crap shoot as to which one will work. You should have a working install of X on your machine now, but it is probably slow as molasses in the winter. ![]() This comes in handy when doing the next part of the installation. If you ever need to get back to OS 9, you can use XPF to do so, or hold Option at startup. It will reinstall the needed extensions and boot you into X. Choose the X partition and hit the Restart button. If you *do* accidentally format before you install, all is not lost, though. Installation should be normal, make sure you don't format the partition you are installing to, as this will erase the modified extensions and BootX. What this does is install the modified kernel extensions and a modified BootX onto the partition you want to install X on, and uses them to boot the CD. Select the OS X CD and the partition you want to install X on and click the Install button. Put in your OS X 10.3 disc and start XPostFacto (XPF). Start up your machine in OS 9, download XPostFacto from here and put it somewhere on your OS 9 partition. Install OS 9 on the second partition (not the less than 8 GB one). In my case, I made the first partition 7.5 GB, and left the rest of the drive (32 GB or so) as the second partition. That being said, you probably only *need* 3 or 4 GB to get everything working. Less than 8 GB is going to get pretty cramped pretty quick, though, so I also suggest getting a bigger HD. If your drive is smaller than 8 GB, this isn't really an issue, but I would highly suggest having OS 9 and OS X on different partitions. On to the install.įirst and foremost start up from an OS 9 CD, and partition your drive such that the first partition is less than 8 GB. I'll probably test this soon so that I can get back my dual monitor setup. I am doing all video on the Radeon 7000 for now, as I had problems with the built-in video on earlier versions of XPF. Also, XPostFacto a17 has some preliminary support for the built-in video of Beige G3s, but I haven't tested it as of yet. Keep in mind 10.3 will only work on G3 and above processors, so older machines will *not* work unless they have a G3 or G4 upgrade installed. It should, but there may be other idiosyncrasies I don't know about. This may or may not work with other Mac models. If you have any problems on a differently-abled Beige G3, please let me know so we can work towards a more complete Howto. These instructions are based upon this machine. Sonnet 400 MHz G4 upgrade w/ 1 MB L2 cache First of all, here are the specs of my machine:
