Nvram Variables Not Saving In Clover UEFI

Recommended Posts

Hi,

I'm trying to save my theme inside of the nvram now that it is used but every time I enter it, upon reboot it disappears.

I am using these drivers:

CsmVideoDxe-64.efi	HFSPlus-64.efi		PartitionDxe-64.efi
EmuVariableUefi-64.efi OsxFatBinaryDrv-64.efi
FSInject-64.efi OsxLowMemFixDrv-64.efi

With rev 1702, I have no issue booting, I also have sleep working.

I think they're kind of working, but I'm not sure:

Thomas' MacBook Pro:~ thomas$ nvram -p | grep EmuVariabl
EmuVariableUefiPresent Yes

I have also tried entering it in the new Clover PreferencePane but upon reboot it is empty.

Would appreciate any help :)

You have all the RC Scipts installed???

No, I'm not sure what they do? Didn't know I needed them, shall I install them all?

EDIT: I just installed "Install RC scripts on target volume", I put my theme into nvram, which was fine. Upon restart it was gone again. Do I need to install "Install all RC scripts on all other bootable volumes"?? I triple boot Win8, Ubuntu, and OS X all via Clover UEFI.

You need to install RC Scripts only to OS X bootable devices...

I don't know what could be happening as you are using EmuVariableUefi-64.efi and still not working...

Do you have any FusionDrive or Software RAID??? If no, you can see nvram.plist hidden at the root of you OS X partition???

What do you see at /Library/Logs/CloverEFI/rc.shutdown.log???

Ok I have a recovery partition too but don't think that makes a difference. I only have one install of ML, with Ubuntu UEFI and Win8 UEFI. So I guess I don't need to install the RC scripts anywhere else.

I think everything is working now, I checked to see if I had nvram.plist in the root of HDD and it was there. Also I checked that log and everything seemed to be fine, the script was writing to the nvram. So I decided to go into Clover PreferencePane and change the theme name to black_green. It asked for password, it wrote to the nvram. I restarted and this time it saved, so I guess all I needed was the RC scripts installed.

Now I have some questions, what other variables can I put into nvram? I see some people having line log count, whats that?

Also in the PreferencePane it doesn't show a preview of the theme, is that because I don't have the EFI automatically mounting? Should I set it to automatically mount? Whats the advantages/disadvantages of mounting the ESP on boot and how do I do that?

EDIT: I have no fusion drive or software RAID.

There is the possibility to use the following NVRAM variables with Clover...

Clover.LogLineCount = Number of lines to be used by system.log

Clover.NVRamDisk = Disk to save NVRAM

Clover.MountEFI = EFI partition to be mounted

Clover.Theme = Theme to be used

Clover.LogEveryBoot = Save an specific boot.log file for every boot

Also, I believe that Slice are implementing an feature that we will be able to set boot-args also using NVRAM variables...
