PostPosted: Sat Jun 26, 2004 7:52 am    Post subject: [OT] boot iMac from CD Reply with quote

hello,

i have an old iMac and I want to install Gentoo on it.
I burned the minimal installation iso on a CD. But my problem now is: HOWTO: boot from the CD?
I read something in google and here in the forum (and handbook) but "c" wont work. I also tried other kombinations (Alt-Apple-Shift-Backspace and similar) but nothing worked...

Sorry: I don't exactly now the hardware settings and other details about it because I just bought it in eBay - but it's pretty old (200Mhz, 4GB HDD)...

Has anyone an idea?

thx in advance

Did you try to boot the Mac from the hard disk, put the CD in and then select it as boot disk in the Startup Volume control panel? That usually works.

If you have MacOS 9 on the box, boot and click on the Apple menu in the top left corner. There you have a submenu "Control Panels" which contains "Startup Disk" (falls Dein OS deutsch ist: Apple Menü -> Kontrollfelder -> Startvolume). There you can select the CD as startup disk and click "Restart".
If you're on OS X, click on the Apple Menu and open "System Preferences", where you have a "Startup Disk" control panel.

hello,

sorry I just saw the menu option and didn't try it -> big mistake as I saw...

someone told me that my iMac just can handle a HFS burned CD?
I burned the ppc-gentoo-iso with k3b on my x86 machine...
Does anyone know how I can burn the CD with HFS or shouldn't this be any problem?

The problem is, that if I insert the CD in MacOS9.1 he always want's to initialize or abort -> both ways finish by "ejecting" the CD.... and because of this (I think) the CD device is not listet in the "startup volumes"....

thx in advance

I can imagine that 9.1 might not deal with the CD well - I doubt it's HFS (silly for a Linux CD, let alone ANY CD), but it shouldn't matter too much as long as the CD is in the drive during initial startup. One thing to try would be holding down the option key during startup, which, depending on the age of the machine, should present you with a list of available startup disks. The Gentoo CD should be one of them. I'm surprised the "c" trick didn't work, though.

The CD should be allright if you just burned the image... if you can mount it with your regular Linux box and see the files, it should be OK.
Another thing you could try boot-wise is to switch the computer on and hold the Alt-key (true Macians call it "Option key"). After a short while, you should be presented with a couple of Icons, one representing your harddrive, the other one the CD you try to boot from. Click that, then the button with the arrow to the right. If that doesn't work, you should double-check whether the CD is OK, maybe you can try it in a friend's Mac?

hello,

thx for your hints...

Also the "Alt/Option key" (finally I now what the option key is :)) didn't the trick.

Yes, I can mount the CD on my linux box. But I cannot boot witht he x86 or my amd athlon from it -> is this correct?

in the /boot directory on the CD there are only G4 and G5 listet -> my iMac is G3...
might this be a problem? because in the handbook there are more listed (G3, G3-SMP, G4, G4-SMP, G5, G5-SMP)

I could not test it on another mac :)

thx in advance

When you're booting your iMac, hold down the option key and the c at the same time. Newer macs take just the C, I believe, but older ones need the option+C. If it's an old world mac (and it sounds like it might be), you won't be able to use YaBoot, but will have to use Quik, or something else. The gentoo instructions aren't very clear on how to do this, but I believe you'll have to boot into 9, and boot into linux from there...which means, you'll need to resize your 9 partition before you install anyways. :-S

Good luck

Does holding down Command (Apple), Option (Alt), O, and F together on boot do anything?

FYI - if it does, you'll need to type "boot" or "mac-boot" to get it going again.
