Hi,

this may sound akward but I cant find my EFI partition or my boot.plist anymore.
Its been a while since I last put Yosemite to my system. Back then I read some manual here on tonymacx and decided to go for an installation where I seperate my win disc and my mac disc.
After that I remember having troubles to boot normally into win7. So I had to adjust some things - which I cant recall.
Anyway, If my thinking is correct I went for an installation where all the post installation kexts etc. would be put on the seperate EFI drive.
Now somehow I cant locate the drive anymore, or in other words, where do i need to perform my changes?

Mac-Pro:~ edje$ diskutil list
/dev/disk0

I mount the EFI partion with EFI Mounter v3
As it seems I have to EFI partitions. One together on the win disk, and one on the mac disk.
The one on the windisk (disk1):
Mac-Pro:EFI 1 edje$ ls -a
. .Spotlight-V100 ._.Trashes
.. .Trashes .fseventsd

The one on disk0
Mac-Pro:~ edje$ cd /Volumes/EFI
Mac-Pro:EFI edje$ ls
2016-11-28 (a folder I just created)


And the Extra folder from the yosemite disk:
Mac-Pro:Extra edje$ ls
Themes org.chameleon.Boot.plist
modules


If I perform changes ony my boot.plist from my extra folder on the yosemite disk, they do not have an effect. e.g. the theme that is in the theme folder is not the one that is shown on startup.


Can anyone assist me with some guidance here?

Thank you in advance,

best,

I removed my win disk and chamelon was booting normally into yosemite. This means chamelon must be on my yosemite drive. The question for me now is just: where is it all located?
If I use the efi mounter again to mount the efi partition - it is still empty, except for the dummy folder I created.
Am I mounting the drive in a wrong way?

If you installed Clover in Legacy mode then the config.plist is on your system drive in the /EFI folder.
If you installed Clover in UEFI mode then the config.plist is on your EFI partition in the /EFI folder.

If you are using Chimera (Chameleon) then the /Extra folder on your system disk is used for the org.chameleon.Boot.plist.

Hi, thx for your guidance.
I am sure I did not install Clover, since I have Darwin/x86 boot v5.0.132 - Chameleon v2.2svn r2463.

And I have the Extra folder, but changes in the org.chameleon.Boot.plist show no effect.

e.g.
Code:
<plist version="1.0">
<dict>
    <key>EthernetBuiltIn</key>
    <string>Yes</string>
    <key>GraphicsEnabler</key>
    <string>No</string>
    <key>IGPEnabler</key>
    <string>Yes</string>
    <key>Kernel Flags</key>
    <string>kext-dev-mode=1</string>
    <key>Legacy Logo</key>
    <string>Yes</string>
    <key>Timeout</key>
    <string>20</string>
        <key>HDEFLayoutID</key>
        <string>01000000</string>
        <key>Graphics Mode</key>
        <string>"1920x1080x32"</string>
        <key>UseKernelCache</key>
        <string>Yes</string>
        <key>HDAEnabler</key>
        <string>Yes</string>
        <key>Theme</key>
        <string>OSX black</string>
    <key>Default Partition</key>
    <string>hd(1,1)</string>
</dict>
</plist>
I just put the timeout to 20 so I can be pretty sure if the boot option remains quite long, but it does not. after a couple of seconds its gone. (and the theme shown is not OSX black).

any other ideas?
