Hi,

I have 2 partition on one HD. one with leo and one with snowleo.. the problem is that when I select snow leo Chameleon loads the kext on the extra folder of my leo partition... how can i avoid this???

Thank you!

Common problem.
This works best when different OS installs are on different drives. That way you can select the desired volume via BIOS drive selector and guarantee you boot the bootloader controlling those kexts.

First check both your partitions UIDs with Disk Utility (Info on disks), they must be different. Then add this to each of the /Extra/com.apple.Boot.plist files

<key>boot-uuid</key>
<string>UUID of this partition</string>

replace "UUID of this partition" with the real UUID of that particular partition, in the form
XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX

You must do it to both /Extra/com.apple.Boot.plist files, each with its own UID.

From then on, Chameleon will be able to differentiate the 2 partitions /Extra contents

Thanks for the help. I solved by using efi v9..
