Indeed, attached my current that works for me, but it should not differ too much from the one in the first post.

Thank you, I will try that... do you beleave that in some bright future USB 2.0 will be working? Or is that something none kext or DSDT patch cannot solve...? You know, most of the WiFi usb dongles are 2.0 ...

That should work, from what i know, it's only the 2.0 flash drives that do not work. It is possible to get them to work, but then, the USB 3.0 devices will only work on USB 2.0 speed.
If that is ok, then download the IOUSBMassStorageClass and IOUSBFamily from here: http://www.insanelym...60#entry1881406

Thank you very much Lejenk.., I dont care about speed, more important is compatibility for me... by the way DSDT you attached works like a charm!! At least I know that Clover is loading custom DSDTs :D Have you tryed EFI partition I have shared?

I have, even spent hours on the phone with the idiots from Dell, they could not help me, came down to: "Wait for a bios update".
I could boot clover once, so it works in some kind of way, but not as it should -_-

I was also on dell line for hours... so you have switched to UEFI boot... disabled secure boot and enabled Legacy option ROM, right? If you want, you can download image of Arch Linux(Kubuntu,Ubuntu, whatever...) and open SSH port for me, I can analyse your PC and can also install it on flash drive in UEFI mode.. if you dont trust me, you can remove HDD from NTB.. its up to you, but I have spend 2-3 days instaling OS(es), especially windows, but if you have A12 as me, I dont beleave that UEFI on your PC is in worse shape than on mine...

Or you can place other HDD(or bigger Flash drive) and we can Skype or somethink, it is better to see what you see so I could share my experineces and hints... well its up to you... I am willing to help you, since you contributed so much to our 7720 which is handy to me :) I offer only compensation :P

Yes, could only boot clover with Legacy ROM disabled btw.
I have A12. Just wondering, how do you want to Skype, when i have to reboot the system, that way you can't see what i see :P

It's fine like this for now, perhaps the in the future. No need to compensate anything, this is what we do :superman:

Attached a few screenshots, it shows on the right the SSDT with the info, on the left where to add it.
Well, just also noticed, i forgot to add PSS to CPU0, have to look in to that again -_-

To disable the GPU, you will also need to add the following:

Method (PINI, 0, NotSerialized)
{
\_SB.PCI0.PEG0.PEGP.OPOF ()
\_SB.PCI0.PEG0.PEGP._PS3 ()
}
Goes above Method _WAK

Add the function to Method _INI under Device PEGP, and under Method _WAK as shown on the screen:

Method (_INI, 0, NotSerialized)
{
PINI ()
If (LNotEqual (BRID, 0x06))
{
Store (Zero, _ADR)
}
}

Hope this helps. I'm moving this weekend, so short on time :) will make a detailed guide after that.

I don't know anything about AMD sorry.
Yes, the battery life doubles, and the system will run a lot cooler.

For editing the DSDT to disable the GPU, you will also need the SSDT files, best to create a new topic for this.

No, extract the SSDT files from Linux or Windows, you can use Aida64 from Windows, a video explaining how to can be found here:


Just extract all found SSDT tables, one of them will contain the needed information.
