Clover General discussion

[Asgorath]

I got really tired of having to set "nv_disable=1" in my boot-args when updating to a new OS version on my Maxwell GPU, so I figured out a way to patch the stock NVDAStartup.kext to avoid the panic.  There's one byte different between the 10.11/10.11.1 version and the 10.11.2 version, not sure if there's a better way of handling this other than just having two patch entries.

<string>Maxwell panic fix 10.11</string>

<string>898d14ffffff418d46ef83f80273094c8d3514090000eb34</string>

<string>Maxwell panic fix 10.11.2</string>

<key>Replace</key>
<string>418d46ef9090909090909090909090909090</string>
</dict>

It basically NOP's out the 4 instructions in the middle of this block so that NVDAStartup doesn't try to match a Maxwell GPU.  As far as I can tell, the panic comes from the fact NVDAStartup is incorrectly matching a Maxwell GPU but the stock Apple drivers don't support it, so skipping this avoids the panic.

I would've preferred to match more stuff around the code in question, but there were significant differences in the instruction stream between 10.11.1 and 10.11.2 so I just settled for the instruction(s) directly before the CMP.

 

I thought I had the 10.11.2 patch working yesterday but I just tried it again and I'm still seeing a panic, will see if I can make that work.  Definitely works for 10.11 and 10.11.1 though.

@ Download-Fritz the nvram shows me this "bootercfg %02%00"

 

It seems that clover shows us a fake boot screen, not the apple boot-logo, so that value does nothing

[mhaeuser]

If you didn't enable custom boot screen, it doesn't.

[wern apfel]

No custom logo, i've not read the hole clover code but what is this @bootscreen.c

STATIC EG_PIXEL blackBackgroundPixel = { 0x00, 0x00, 0x00, 0xFF };
STATIC UINT8 whiteAppleLogo[] = {.............

[mhaeuser]

And if you had checked the only reference to that variable...

DBG("Custom boot is using alternate logo\n");

[Pluskat5000Schiffe]

someone has an idea about #8996?

[mhaeuser]

 

First of all I like to thank all contributors of creating the clover bootloader for this fantastic master peace of software.

 

I was reading the clover instructions written by Slice to do a combination of FakeID together with Kext To Patch.

The situation. I have an Intel Nic which is working with the FakeID LAN option but I need to strip off this section in the info.plist 

<key>IOPCISecondaryMatch</key>
<string>0x00008086 0x00000000</string>

of kext IONetworkingFamily\Plugins\Intel82574L.kext to get FakeID working.

I was wondering if its possible to patch this kext on the fly and how to do it. I also read that you need to do Text to hex to coded text but i don't have a clue how to do this and which conversation tools are needed.

At this moment this kext is the only kext which needs modification every time osx gets updated.

 

Any help really appreciated!

 

 

Just rename the key name to something random with the same length

[ValJr]

I have a Asus x99 Deluxe + 5820K with a GTX 970. I am trying to change the resolution of the bootloader GUI but no luck. Any idea?

When the bootloader load Yosemite the screen goes black, I have to disconnect and connect the monitor to get a video signal, any fix?

[cecekpawon]

Hello programmer, its still not possible to inject (both igpu & discrete) display at the same time? All from inject devices section or 1 from efistrings / with arbitrary?

[wern apfel]

while testing i've also changed the boot screen color

Thank you for your tip but it's not working. This is the clover config section I use.

  <key>Find</key>
  <string>IOPCISecondaryMatch</string>
  <key>Replace</key>
  <string>Replacetext12345678</string>
</dict>

Is this correct ?

[davidm71]

You can write a DXE driver to load and launch it from a Firmware Volume. Good luck with porting Clover's file loading to the Firmware Volume File System though.

 

Well that worked like a charm. Was wondering though how do you correct checksums after the ffs file is created? Sonix on Winraid was able to optimise the ffs driver and give it a volume name. I would like to know how to do the same?

 

Thanks.

Good trick!

[Pluskat5000Schiffe]

Good trick!

Slice thanks for the compliment ;-) however its not working. If I manipulate the kext this way manual and try it to load with kextload / unload its working but it is not patched in advance when clover loads. It's not a big deal however sorting this out enables me to make installers etc which have network working while installing OSX.

[Slice]

The kext will not be patched if it is not loaded. But it is not loaded until it is patched. This is the contradiction.

You may force load the kext while I am not sure if it helps.

Or better first install the system and after that patch the kext. Yes, you will not have network during installation. Do you really need this? This is a hackintosh anyway!

[mhaeuser]

What checksum are you talking about? And how do you give a volume name to a file?

hello clover team

i confim to not load kext 10.11 folder in 10.11.2

 

clover load kexts in other folder

 

maybe clover cant recognize 10.11 version in 10.11.2

 

i use latest clover r3330. i'm sorry my english. thanks in advance

Lol indeed I understand it now. Sure it's a Hackintosh but using clover in between makes the difference smaller between a hack and a real mac seen from the OSX side.

Solving patches done by Clover will simplify every installation.

 

Last question how do I accomplish to force that kext to load ? I will post the results of that back.

Something like this:

	<key>KernelAndKextPatches</key>
	<dict>
		<key>ForceKextsToLoad</key>
		<array>
			<string>IONetworkingFamily</string>
			<string>AMDFramebuffer</string>
			<string>IOAudioFamily</string>
		</array>

But sorry, this is not my invention.

[mhaeuser]

I think you need to provide the full identifier, so, e.g. with "com.apple.'-prefix. Should find it in the kext's Info.plist

 

EDIT: @davidm71 post #363: "After having done several tests with my ASUS P8Z68-V system, I found out, that the other 3 NVMe modules named Nvme, NvmeSmm and NvmeInt13, which I am currently still offering within the start post, are maybe not even required!". That's what I have said from the very beginning.

post #366: "Some minor hex code incompatibilities have been corrected." What are "hex code incompatibilities"? Would be nice if he shared what he did. Otherwise might just need to compare the files, but I don't have the nerves right now.

No harm leaving those three files I wonder except maybe eating memory. I'll get rid of them in my next bios edit. Anyhow the guy that optimized the file isn't sharing how he did it. I asked him nice and I'm very curious how he did it.

 

Thanks.

This wasn't working either.

 

I solved it by using a much easier trick. 

I made an Ubuntu Live USB boot stick. Booted from that and used the ethtool which enables eeprom reprogramming.

Ifconfig gives the interface name and that name is different from most examples you see on the internet. The interface was called "enp2s0"instead of "eth0"

I wrote new values for SubSYSID's

sudo ethtool -E enp2s0 magic 0x10d38086 offset 0x16 value 0x00
sudo ethtool -E enp2s0 magic 0x10d38086 offset 0x17 value 0x00
sudo ethtool -E enp2s0 magic 0x10d38086 offset 0x18 value 0x86
sudo ethtool -E enp2s0 magic 0x10d38086 offset 0x19 value 0x80

This will match values for IOPCISecondaryMatch values in Intel82574L.kext so now together with FakeID -> LAN = 0x10f68086 the kext is loaded.

You can even decide to change devid of your Hack Card to match a real mac card but I decided to leave it this way. I found the trick partly in this topic.

So now evertime I install a new hack i don't have to worry about en0 witch is not there during installation etc.

hello clover team

i confim to not load kext 10.11 folder in 10.11.2

 

clover load kexts in other folder

 

maybe clover cant recognize 10.11 version in 10.11.2

 

i use latest clover r3330. i'm sorry my english. thanks in advance

No problem here,, it still load from 10.11   

Same as you,, i use Clover R3330

[Gogeta5026]

I'm sure somebody out there has run into the same problem as me, so here goes....

Clover is working 99.8% perfectly except for when I try to boot Linux off of it. When I reach the GRUB menu I can't use my mouse or keyboard (which are Logitech wireless/USB). DOES ANYBODY KNOW HOW TO FIX THIS??? Mouse/Keyboard work fine on Clover, after booting into MAC, after booting into Windows 10, after booting into Linux. It's just selecting something on the GRUB screen is my problem.

If anybody can help... THAT WOULD BE GREAT AND APPRECIATED!!!
