Find in this page, disc images which when correctly burnt to a blank CD-R, will properly boot a Mac from a 3rd party (i.e. lacking an Apple ROM \/ not being an apple supported model) CD-ROM drive, including CD writers. This is a difficult thing to achieve, and has several difficulties, one of them is needing a CD that will allow it in the first place.<\/p>\n\n\n\n
Generally, original Apple Installer CDs will boot a Mac even with a 3rd party drive, but a lot of images online have been… not extracted perfectly. This page contains a mixture of “fixed” images and original ones. Generally the original images are more broadly compatible, but I’ve done my best with my own!<\/p>\n\n\n\n
This “fixed” image should boot most macs with a 32bit clean ROM, namely from the Macintosh IIci onwards. I haven’t tested, but CDs might work to machines as new as the Power Macintosh 9600.<\/p>\n\n\n\n
