Lenovo ThinkPad T420 with UEFI Only

[Yum]

hmm. ok. well it seems to work for many of us on T420. if i use the built-in EDID i get lots of glitches and buffer hangs. as soon as i use/inject this EDID - zero glitch - zero hangs.  sorry it does not work for you.

can you send me your clover config plist for boot?

[tluck]

@yum - see my sig for link to post with full zip  - which includes clover /EFI 

[ag6952563]

@AJ 

 

1)  /.IAbootfiles  or something like this is created by the installer on the OS partition you were upgrading by the Install OSX.app ...  if you have HFSplus.efi vs Vboxhfs.efi in your clover drivers folder, then clover can boot from this installer bundle upon reboot. (just like a real mac)

 

since you aborted the install process by not restarting using this bundle, you can get rid of this folder now.

 

2) the installer will create (or update) the recovery partition - which is a 650MB partition on your OS HD. ( i would keep this.)

Thank you guys. I have deleted the .IABootfiles and the "Install Mavericks from..." is no longer there, good.

 

And for the recovery partition, it is actually there. The problem is that it doesn't boot, it complains about the AppleHDA kext. I'm trying to install the modified kexts to the BaseSystem.dmg that is in the recovery partition to see if I can boot from it. It would be useful in case of problems.

I used the following command from terminal to enable debug mode in Disk Utility and view/mount hidden partitions from the debug menu:

defaults write com.apple.DiskUtility advanced-image-options -bool true

 

Once mounted, I have converted the read-only .dmg into a read-write, applied the custom kexts using Kext Wizard, then converted .dmg into a compressed .dmg, and replaced the BaseSystem.dmg into the Recovery Partition. It almost boots now... still looking at it...

[tluck]

@aj - there is a much easier way to boot recovery partition!!! it is essentially the same thing as the USB installer - which requires extra kexts.

 

so stop at clover GUI

use clover shell to rename OEM so it's not in play for this and boot recoveryHD using the top level config.plist which will inject (custom) kexts from 10.9 

 

shell commands
 

map fs0

fs0:

cd /EFI/CLOVER

mv OEM OEM.NU

exit

hehe, that seems easier... indeed... I will try it...

take 2 on EDID HD3000 fix.

 

OK this theory is working in practice!  Theory: bogus panel size was the culprit

 

I changed just the panel size from 309x174 to 310x174. I can't get a glitch/hang on 10.8.5 or 10.9.0 using this edited EDID info.

It was NOT sync sizes as i originally thought - that attempt eventually hung.

 

tetonne - your EDID seems to be 309x173? maybe if i gen one that has 310x174 for 1366x768 resolution? i will post a new one test EDID later.

i noticed these EDIDs (mine too) specify a max size to be 310x170 but the panel was set to be only 309mm... it stands to reason the max cannot be bigger than the panel!

@tluck "EDID seems to be 309x173?" I don't know (don't understand in fact)

send me the new edid when it's created, i'll test and feed back.

[honeywell]

@tluck, could you generate an EDID with that panel size for 1600x900? I tried all the EDIDs so far (except the one in post #629) and I'm still getting hangs and glitches (though rarely). I'm also on 1600x900.

Can you generate a new edid for 1600x900? And explain which parts(number) to change?

Thanks i ll try

 

i have already tried your edid with 36AE10 but no luck, always glitch

[tluck]

@honeywell - see post 629 ... and the clover bundle has this same working (for me ?!) EDID for 1600x900.  the OEM 1600.900 config.plist is set up to inject the EDID and i also put in the DSDT (for non-clover).

 

... i don't know why this particular EDID works for me (and others ) but not for all.  

 

if you are NOT injecting this EDID (with product 2e2) , then please run : ioreg -l |grep EDID and post the EDID - maybe we can make sense of it and get a working one. 

[Yum]

my original ioreg:   d-h.st/7iC

[Yum]

you see this http://www.insanelymac.com/forum/topic/293500-i-found-the-brightnesss-working-principle-and-i-dont-need-genericbrightness-at-all/  ?

[tluck]

@yum - i will look at this post.  but I already have LCD brightness (16 levels)

 

so i took at look at  your ioreg EDID dump. and the first thing i noticed is you have 1600x900 but its on a 17" vs 14" so here is an EDID that you could try that has the same info - but i tweaked the params slightly (changed) to match the values work for me but with proper sizing.

 

see 4 value changes on line 50

 

your EDID

 

new EDID to test - take string below and put in Clover config.plist

@tetonne

- that EDID is only for YUM (or others) with 17" LCD 1600x900!

 

are you getting glitches or hangs with your default/built-in EDID? you have 1366x768 native LCD?

are you getting glitches or hangs with your default/built-in EDID? you have 1366x768 native LCD?

No glitches or hangs on my 1600x900 and 1376x768 with dualink 0 (dualink 1 doesn't work here)

but better customs are welcomed

 

I test the EDID provided 

my feed back here :

 

One more thing : Thanks tluck

[Smith@@™]

@tluck, thanks for your hard work on this, it's appreciated really.  I have the same edie like yum, i have controlled it by yum link in some previous post. I think that also laptop is probably same family with same screen 1600x900 on 17 inch. 

So i try your custom edie, i have past it directly in display/overrides and it is seen correctly but i have always artifacts, after 2-3 reboot or something of similar. Problem for me is still unsolved for now. I can try other if you have other ideas. I think that will be same for iim cause original edie is the same. 

But why all this is happen on clover instead on chameleon (and/or smcping daemon) there is not this artifacts problem?

Btw thanks 

[tluck]

@Smith@@ - how are you injecting the EDID? i found that putting one in /S/L/Displays/Overrides does not actually override the built-in EDID! However, I found that if I put a new/different EDID in the DSDT or inject by clover then the system will use it. it seems that if the system can find one in the LCD hardware, it will use it versus use one in an Override file.

 

I have been trying to figure out what is special about the EDID that works for me versus the built-in. i don't know why my built-in EDID is glitchy but an alternative EDID is absolutely perfect. And i had glitches on Chameleon/MBR before i switched to Clover. 

[Smith@@™]

@tluck i think that your theory about override is right because with same edid in previous post, that for yum (my model is in fact exactly the same), if i override it in display/overrides and so in vanilla method, i see in profiler that name is correct (LCD HP in this case) but override is probably not complete, if instead use the same last edie in clover i have completely black screen after all loading verbose end screen begin always more bright, it throb, vibrates and then nothing.

 

So i think that i must try all from clover. Can you make a new edie for testing?

 

Ed: i have another question, now i have injected original edid with clover. But The COMMENT in graphics setting, in this case i choose "GLITCHES?" is different from name in monitor profiler, i mean, name is taken always from original override in Display/Overrides. But i think that clover EDID is working cause with previous edid had black screen with original not. But about name is right? There should be also an override of COMMENT parameter from clover?

Yup, it's same DV7 hp  

 

@tluck, thanks so much for all help. I have done same smith@@ tries and result is the same. Now i'm starting to inject the edid directly from clover. I will test your other edid

[tluck]

@Smith@@ and Yum

 

this is what you need to put in your config.plist - it this is a modified EDID (detailed timing section) but has the same product/vendor.

this is what you need to put in your config.plist - it this is a modified EDID (detailed timing section) but has the same product/vendor.

In test, but i see already one artifact, but still in testing.  But before question, i should see this: HP 17" 1600x900 in System Preferences --> Monitor --> Colors ?

 

Or not, because seems that name is not override correctly..

 

Edit: artifacts again..     but i don't understand about before question, if edie is override correctly

[Smith@@™]

Maybe chameleon and clover read something in different way. Common problem is artifacts on clover and more less (avoid totally with smcping daemon) on chameleon. If i can understand what is that "something", but honestly i have done practically every form of tries LOL

 

 

Can be also my 16 GB of ram, but i had the same problem also with 8. On mavericks then patch intel kext for "downgrade" gram is not work. It see for intel always 512 MB of ram

No glitches or hangs on my 1600x900 and 1376x768 with dualink 0 (dualink 1 doesn't work here)

but better customs are welcomed

 

I test the EDID provided 

my feed back here :

@Smith@@ -- bummer. too bad that this EDID does not work for 17" HP.  

 

to answer the question. the comment in the Graphics config.plist is just a convenience to remind one what the EDID is for. as far as i can tell, the system will use the contents of the file /S/L/Displays/Override/Vendor-X/Product-Y by matching what vendor/product is in the EDID. but it gets the EDID first by looking at the LCD/Display HW if found then it will use it if it is a complete/valid EDID and then ignore anything in the same file i.e. EDID in the file.

 

the only way i found that system would use a different EDID was to use Clover to inject (overwrite) the EDID or put in DSDT in IGPU as AAPL00,override-no-connect property. i guess i just got lucky to find an EDID that works. TimeWalker mentioned he used SwitchResX to rework his EDID to a glitch-free state.
