Create a customized OS 9 troubleshooting CD System
Under Mac OS 9 and earlier system versions, it has been difficult, if not almost impossible, to create your own boot CD disc without special software like Toast. This feature would be useful if you wanted to create your own boot discs with copies of such utilities as DiskWarrior or Norton Disk Doctor on them. Now, with Mac OS X and Disk Copy (and a CD burner), you can - without Toast!

Read the rest of the article for the how-to...

To create your own bootable and "blessed" CD containing Mac OS 9.x and whatever additional utilities you'd like to include:
  1. Locate your computer's Software Install or Mac OS bootable CD and insert it into your disc drive.
  2. In Mac OS X, run Disk Copy. This application can usually be found in your /Applications/Utilities folder.
  3. Select "New Blank Image ..." from the Image menu of Disk Copy.
  4. Enter your selected "Save as" and "Volume name", and create it on the Desktop. To burn to a CD, you would need to select at least the 500MB option under the Size selection.
  5. From your Software Install/Mac OS CD, drag its System folder to the new disc image volume on the desktop which you just created. The 'disc image volume' will look like a disc drive, named with whatever you put in the "Volume Name" field.
  6. Now, install whatever utilities you would like to the disc image volume. Optional: Upgrade the OS on the disc image volume if you'd like, by running OS 9 updates and applying them to the disc image volume.
  7. After the disc image volume is prepared, drag the disc image volume (NOT the image file that ends with a .dmg!) to the trash.
  8. Back in Disk Copy, select "Burn Image ..." from the Image menu.
  9. Select the .dmg file you created earlier, click "Burn", insert a CD-R or CD-RW disc, and click the "Burn" button.
After a few minutes, you should now have a bootable OS 9 CD!

[Editor's note: Creating a bootable "troubleshooting" CD is an important part of a disaster recovery routine. I have one with DiskWarrior on it, along with key apps (ResEdit, Retrospect, BBEdit Lite, etc.) that I might have to use in the event of a total disaster.]

Applying updates a no-Go
Authored by: loungeboykip on Jul 12, '02 12:57:40PM

I tried following your steps here but my software install disk has OS 9.0 on it, and when I try to apply the system updates to the disk image it doesn't recognize that the image has a system folder on it at all, even though I dragged the sys folder (9.0) straight off Apple's own disk.

Step 3 of this hint needs to be changed. In the Image menu of Disk Copy, select "New Image from Device." That changes the rest of the hint considerably...

Step 4 Select your Installer CD from the menu. You may have to click the triangle tab before you are allowed to select.

Step 5 Save the disk image.

Step 6 Open up the image by double clicking on the image file, remove OS installers and add utilities to taste. "Ejecting" the disk image saves the changes.

Step 7 Go into Disk Copy and select Burn Image.

That's about it. Updating and installing utilities on a CD image may require some creativity. For Virex I boot into 9, upgrade virex on my OS 9 HD, boot back into X, and move the virex preferences from my OS 9 HD preferences folder into the preference folder on my disk image. I think Disk Warrior will actually install directly to the open disk image. I wouldn't recommend trying to upgrade the system software on the CD image.

My step 5 should read: Save the CD image file in DVD/CD master format. That's a key step.

This was very useful for me because I was just thinking about this the other day and wishing there was a way to create an emergency boot disk. And I was feeling bummed that all I had was my OS9 install disk and thinking what if that disk became damaged. So, I figured its always good to have at least 2 disks that can access the computer in an emergency. I was also thinking about how nice it would be to have my disk warrior, and norton utilities on one emergency boot disk. And now thanks to these helpful articles I'm glad I could accomplish this dream come true! :)

I think I had spoken too soon. I tried to do it the second way (written by mclbruce) and I kept getting an error message after completing step 5. The utility reads the files and when the indicator bar reaches the end and error appears: error 5 (input/output error).

Does anyone have a suggestion on how to get beyond this problem?

I tried this hint and was able to burn the CD but the CD was not bootable. I've now tried it twice, following the instructions very closely. Is there a step that's being left out?

I too have made many coasters trying this. The thing that got me closest was by combining this with another hint, which is to copy the Mac OS Rom file from the hard drive system file, and replace the one which was copied from the startup CD. That gives you a bootable disk, but the system crashed right after initalization, with a "trap error" message. I'd really appreciate some help here!

Create a customized OS 9 troubleshooting CD
Authored by: oddjobboy on Feb 09, '04 08:48:05AM

You know, it turns out that if like me you only want to burn a straight (bootable) copy of an Apple-supplied OS 9 install CD (for back-up purposes of course), all you need do is (within Toast) select 'Copy', then 'File' > 'Save as Disk Image'. When the '.toast' image has been created, eject the original and insert a blank disk, and select 'Record'.
Seems obvious I know, but when there are so many suggested permutations going around, the simple tasks don't always seem so simple.
