SOLVED - iBoot and custom smbios.plist

[bwhinnen]

Hi There,

I want to be able to just restore from backup using the Installation Disk (10.6.3) and iBoot, rather than re-installing etc.

I have a full backup on Time Machine, but my machine is setup as an iMac11,3. Is there any way to change the smbios.plist on the iBoot CD at all as doing a restore, finds the Time Machine backup but as the iBoot is a MacPro3,1 it will not allow me to restore.

Any help will be greatly appreciated.

Thanks,

Brett

Can you explain what you did and also change topic header to add SOLVED

First thing to do is mount the ISO as read/write, the unfortunate thing is that this will mean the ISO image will no longer be bootable, but we'll sort that out later.

Mount read/write:

sudo hdiutil attach iBoot-3.1.0-Snow.iso -owners on -readwrite -noverify

Then navigate to the mounted volume which is now mounted on /Volumes/iBoot. We want to go to /Volumes/iBoot/Extra and then mount the Preboot.dmg:

sudo hdiutil attach Preboot.dmg -owners on -readwrite -noverify

Now we can edit the smbios.plist file:

sudo vi /Volumes/Preboot/smbios.plist

Make the changes you want and then save it off. Then we need to unmount both volumes (don't forget to navigate away from the respective directories before trying to unmount them):

sudo umount /Volumes/Preboot

sudo umount /Volumes/iBoot

Finally we need to make it back into a bootable image and burn it to disk.

Open Disk Utility and drag the iBoot-3.1.0-Snow.iso file to the bottom left:

Then click on convert and change the format to DVD/CD Master and elect save:

This will inform you that you cannot use .iso so can use .cdr or both, I choose .cdr:

Finally just burn this image to a blank CD by clicking Burn.

This will then boot as per normal, but you will have the model identifier you want. For me I changed it to iMac11,3 as this is what my Time Machine backups are.

Simply boot as per normal and select restore from the Tools and navigate to your Time Machine to do the restore.

Cheers,

Brett
