Off-topic but to quickly answer your question, E6420/E6430/E6440 all have Sandy/Ivy/Haswell CPUs with fully support integrated GPUs (HD3000, HD4000, HD4600). Have a look at the guides posted here. You may also want to look at other fully supported E6xxx models such as the E6220/E6230 or E6320/E6330 (even the bigger E6520/E6530 if you want).

Just verified behaviour on my E6220: with or without DSDT + GE=Yes/No, I systematically get full QE/CI with the built-in HD3000 (dev id 0x0126) and vanilla graphics kexts. In my particular case of a 1366x768 LCD, I don't need to set DualLink to 1 of course.

Look at the guides for E6220/E6320/E6420 of similar specs. HD3000 is normally supported OOB, you only need a patched FrameBuffer kext to support VGA output and/or HDMI output, otherwise the vanilla kext will do. With a HiRes display such as yours, you need to enable DualLink through Chamleon boot plist (if applicable of course) or through DSDT.

Can't say I saw any...

If your AppleIntelPIIXATA2 does not load from the Clover kext folder, try to place it in /S/L/E and repair its permissions.

Contact EmlyDinesh then.

Do a low-level formatting using some of the freely available Windows tools. That will most certainly wipe out all existing partitions that may not be deleted by a "standard" repartitioning, especially the hidden ones.

Difficult to say if one is better than the other. One is Broadcom-based, the other Atheros-based. Both are A/B/G/N cards and work OOB. I tend to prefer Atheros due to ease of use with eventual DSDT patch.

So... EBIOS errors are gone?

You could always download a fresh copy of the 10.9.5 Combo Update and try apply it again.

You can try others like VoodooBattery of AppleSmartBatteryManager. All available on the web.

Well, first of all you did not specify which kext you're using... Then I suggest you look into the bootpacks I recently published and grab the battery manager kext from there.

It may not influence things but: you've set nVidia to true at the same time as Intel you're not faking Intel desktop model id 0x0412

Did you try to simply reset the BIOS to default settings and then just configure SATA mode to AHCI? I found this necessary a couple of times after getting unexplained KP such as yours...

Are you sure you've got the bootloader installed properly on your keys? How do you partition/format them?

Flat CMOS Battery would normally trigger a BIOS error at power-on as the other settings would be back to default too.

I'd check that everything was properly fitted physically. That little flat ribbon cable is not the easiest of all to refit on the ZIF adapter side. I've also experienced situations where an external USB device (key of HDD) would behave the same and it was a problem of partition scheme/format type: the key or HDD would not be recognized when partitioned GPT with OS X extended format, only if partioned MBR with FAT/FAT32 formatting. I'd be surprised if you had such similar problem with a SSD but you never know... Or the SSD could simply be slow to get powered up/responsive at POST.

Could be the adapter, could be the SSD, could be the BIOS... Difficult to say... If you're not running the latest BIOS (A09), update it.

Re-install your bootloader and try again. Then, try and repartition and/or reformat your USB key. Please note that some keys do not like GUID/GPT partition scheme (I experienced this myself with a couple of cheapo 32Go keys). If you're using GUID scheme, try FAT/FAT32 and vice versa. If you still do not succeed, try a different key. An 8Go USB key from a respectable manufacturer really cost pennies these days.

I guess you were actually referring to EDP, not myHack (which really is the method I've been advocating for years now), in which case, true, I've stopped using it many moons ago when it started to go wrong for the D Series and, as a matter of fact, I really no longer needed it. This being said, I can fully understand that many people who do not have a large experience in Hackintoshing do seek a one-stop do-it-all easy tool to convert their PC into a fully working Hackintosh. It is what EDP was always about. It may be unfortunate and regretful to many people, but EDP underwent major re-engineering some time ago and it clearly proved a little... overwhelming... I've recently started posting full packs for the D620/D630 models in response to users' frustration with regards to your exact same observation. I'm about to do the same for the D420/D430. It takes a little time as I've not kept SL installations on most of my D Series laptops and have to proceed with reinstallations to ensure I don't post anything erroneous. I could probably do the same for the D830 (Intel GMA X3100 & nVidia NVS 135m/140m) -I actually have an old ML or Mav image backed up somewhere- but can't 100% verify the packs as I don't own such models. I can ask my friend her D830 NV but it'll take a few days to subsequently post something on the forum. Understand that this is a "hobby" for everyone, not a paid job. As such, whilst I can sympathise with the frustration of impatient people after a (sometimes long) while, I also ask that they consider this very fact: it's a hobby; support and tools are provided by people who volontarily spend (a lot of) their spare time on helping Hackintoshers. It's also not a matter of money, so any handful of statements about being ready to pay (what would only be pennies) to get the tools would be futile. This is OSXL, not TMX. I have myself received several very sympathetic messages from people who were surprised I never got a penny for my help but if I then challenged them to do so, they usually became very silent... Strange, eh?

Check you connections. Easy mistake is to connect the ribbon cable the wrong way.

That or look for the related DSDT patch and apply it. From memory, it's part of the patches provided with DSDTEditor package. Available off many sites, notably olarila forum.

Did you do the (strange) partition resize as mentioned in the thread?

Why don't you boot your installer key and rollback the previous version of Clover?
