Not genuine mac os 9 install disk10/31/2022 ![]() ![]() ![]() I'm an Apple Certified Service Engineer, but you don't need that qualification to gain the above knowledge. Also I make a bootable utilities CD and by simply updating Mac OS ROM and the other extensions it boots my G4 (MDD) well. When I upgraded from a G4 (Digital Audio) to a G4 (MDD) I just cloned my existing 9.2.2 install onto the new ATA/100 drive and then added in the new Mac OS ROM and new additional extensions. oh and don't forget the newer Apple CPU Plugins. NOT GENUINE MAC OS 9 INSTALL DISK DRIVERSThere are other newer hardware drivers that you might want to include, such as newer ATI driver update and newer FireWire Support extensions. You can copy the Mac OS ROM 9.5.1 from your G4's System Folder. In order to get your previous 9.2.2 CD to work you simply copy the System Folder from it to a new Image and replace its Mac OS ROM with Mac OS ROM 9.5.1. In actual fact these models require Mac OS ROM 9.5.1 or later. It simply includes a newer Mac OS ROM than was on your version of 9.2.2. The Power Mac G4 (MDD) does not have a special version of 9.2.2. It is brand new hardware and each time there's new hardware the Mac OS ROM file has to be updated to run this new hardware. The reason your existing Mac OS 9.2.2 CD wouldn't boot your machine is the same reason a Mac OS 9.1 CD couldn't boot it either. Perhaps the editor was embarrassed or something.ĭespite having a new ATA/100 bus the Power Mac G4 (Mirrored Drive Doors) is no different from any previous Mac model. I emailed this to MacFixIt, they normally post my ramblings. Everything else I need on my Mac runs under Jaguar. ![]() Until Apple comes up with an OSX CD that permits me to include other utilities (besides Disk Utility), we still need OS9.īy the way, I have no other use for OS9. In any case, I now have a "master" CD that will serve as a basis for any "emergency" discs I might require for OS9 utilites. This might have been a quirk that occured on my system because of the manner in which I built this CD. Don't mess with the Startup Disk control panel when booted with this CD, as it seems to hang the OS subsequent to changing the Startup disk when attempting a reboot. Burn the CD.You startup with this CD in the usual manner (hold down the "C" key).Make sure any support files required by that utility are placed in the appropriate folders (like Toast's extensions, etc.). Drag over any disk utilities (like the OS9 Utilities folder, Norton Utilities, Toast, etc.).Don't remove the files from there or your Mac will not run in "Classic" mode (though OSX might offer to add those files later. Note that we're talking about the System Folder in the Toast window and NOT the "genuine" System Folder on the HD. Open the System Folder in the Toast window and remove the three files that start with the word "Classic".Drag the OS9 System Folder over to the Toast window.Click the "new CD" button at the bottom of the Toast window.If you leave it as "Mac OS Extended", it will not work! (MacOS Extended CDs are not bootable!) Set Toast to burn a Data CD in "Mac OS" format.Startup in OS9 (the OS9 that's already on the main HD that came with your Mac) I've not been able to get this to work when attempting this under OSX.It's not perfect but it does work and has allowed me to make an OS9 "emergency" CD. I've managed to define a method to create your own bootable OS9 CD that -will- see the ATA/100 bus. The result is that any HDs on that bus do not come up on the Desktop nor (it is reported) are those HDs seen by OS9 disk utilities. NOT GENUINE MAC OS 9 INSTALL DISK SOFTWAREWhat I mean is that the new 100MHz ATA bus is not recognized by the software on an otherwise-bootable OS9 CD. In addition, a "generic " 9.2.2 CD will not boot these units "properly". In case you haven't seen the reports elsewhere, the latest Dual-G4 minitowers ("Mirrored Door" or "WindTunnel") do not come with an OS9 bootable CD. ![]()
