Installing OX9 and OSX on the same machine

[HiVoltage]

I need to have both OS9 and OSX installed on my PowerBook.

I've just upgraded from an old iBook and I used to have OS9 and OSX available in the startup disks.

Running Classic Mode under OSX is not appropriate ... I need to be able to boot into OS9.

I do software development and need both operating systems for testing purpouses and classic mode won't allow me to throughly test the software.

I tried to install OS9 and it doesn't appear in my startup disks. I tried to "restore" OS9 using my iBook CD's, but the CD won't load on my PowerBook.

I am screwed if I can't get this working, my work depends on it - need all the assitance I can get.

Thanks

Hi,

You might be out of luck. Recent ibooks and other macs are not dual boot. You may be stuck with using classic. The only other alternative may be to buy an older mac from ebay to use for your testing.

I have a beige G3 that I've kept for this sort of thing and more particularly for pluging all of those SCSI and local talk devices I have into.

Best wishes and good luck

Phil

Thanks,

I kind of figured this will be the case ... I was just hoping that I could do it from the same machine.

DOH!

Your Apple got Firewire? Maybe this will get you close.

I bought a Iomaga 20 GB External Hard Drive with Firewire and cloned my entire system to it when I replaced the Hard Drive in my Powerbook. I went to System Preferences and told the machine to start up from the External Hard Drive and it did.

Now, will it boot from 9? I noticed that the option is there to do so.

See this thread for more info.

yep, if your drive is bootable, you can change your startup disk and basically have two different machines on the same computer. you'll need to have your applications on the second drive as well because by default the OS launches all applications from the drive in which the file resides, so you may run into a snag there. But yeah, get youself a bootable drive and install 9.2 on there.

I could be completely wrong, but I've been told (or read somewhere) that the newer AL powerbooks cannot boot OS9 period.
