I just got another PowerBook, and the disk had been wiped by the prior user, and all it did was boot up to the blinking mac face. So not very useful. I did luckily buy some CD’s from a user on reddit a few months ago, so I had 10.4 install DVD, and an install of 9.2.2 for the emac.
Now the OS 9, is an install disc, not one of the recovery discs, and naturally the aluminum powerbooks don’t boot OS 9, so I’m kind of out of luck for getting Classic working, or so I had thought. I copied the System Folder from the CD onto the hard disk, and told the classic applette to boot it, and it updated some system files, and then gave me this fine message:
So this got me thinking, back in the Sheepshaver days when trying to boot from an ISO as a disk file, it fails the same way because the image is read/write. If it’s read-only it does boot up however. So I used disk util, and made a new read-only disk image from a directory, and pointed it to a directory that I’d moved the CD’s system folder, desktop to. After mounting the read only image, it booted!
Now for the best part, I then kicked off the installer from the CD, and had it install a copy of OS 9, onto the OS X disk.
It’s worth noting that just about every optional install fails. It’ll come back with an error, and you can skip the component. It’s probably just easier to install the minimal OS image.
But rest assured it really does install.
After the install you can eject the CD, unmount the read-only copy and tell the classic to stop and then boot from the new installed copy of OS 9 on the OS X disk. It didn’t interfere with my OS X from booting, although the ‘sane person’ would probably have disk image make a small (1gb) read/write virtual disk, and have the installer install to that.
So to recap, copy the system folder from the CD onto read-write media, and let classic update it. get it to the point that it’s not happy about being mounted read-write. Move it to a read-only disk image and have classic boot from that, and then run the OS 9 installer to install itself to whatever target disk you need or want.
I’ve run Netscape 4, IE 3 & 4, QuickTime 4, and the SIMS version 1 (the OS 8/9 carbon version). using 10.4.0 on an aluminum powerbook.
I don’t know if anyone else has done this, I couldn’t find any real concrete guides for installing OS 9 from OS X. So here we go.
