I tried the MacTron discs and they dont work. I purchased an external burner and toast titanium. I followed these directions to burn OS :
This is a way that can be used with different burning applications (they just have to be able to install the necessary wrapper code to make a volume bootable):
*start Disk Copy (usually located in the Utilities-folder), select Image>>>Create new Image... from the menu
* fill in a name for the CD, make sure that a size of 663,000K (CD-ROM 12cm, full) is selected and "Mount Image" is checked (checking the "Zero blocks"-option also is a good idea)
*save the image (usually to the desktop)
*you can now use a Mac OS installer (your original Mac OS install CD, for example) to install a System Folder to that disc image (once installed, you can also update that system using any [download] updater) and add all applications you want (try to install them whenever possible, because simply copying things over will not always work)
*when using Mac OS 9.2.x, remove these files from the System Folder: "Classic", "Classic Support" and "Classic Support UI"
*now run those applications on the disk image which require registration (e.g. a serial number) - otherwise they will ask for registration when booted from the CD and therefore might not work
*disable any AutoUpdate- / LiveUpdate-features, as the applications on the CD can't be updated anyway once they've been burned
*when running applications from the disk image, some applications might create preference files in the System Folder you are currently booted to - in that case, just copy those preference files to the System Folder on the disk image afterwards
*now you should remove anything that may have been stored in "Startup Items" or "Shutdown Items" inside the disk image's System Folder; you might also want to remove some useless control panels, extensions, etc. and set the Energy Saver control panel to "never go to sleep"; also set all other preferences/control panels to your preferred settings (once again, you might need to copy files over from the System Folder you're booted to for these changes to take effect)
*when finished, burn the CD [when using Toast Titanium, set it to "Other", select "Mac Volume", click "Select", choose the disc image from the menu, select "bootable" and click "Record"] - in case you're given the choice, make sure to select "Mac OS Standard (HFS)" volume format, not "Mac OS Extended (HFS+)"
