[Solved] Dell 7490 i5 won't boot to installation

Recommended Posts

Since the original topic is resolved, we can close this thread. For your wireless troubles, we have plenty of DW1820A-related threads on the go, including those I linked you to in 2nd post.

 

Regarding the brightness control keys, Jake, indeed patching through SSDTs would be the ideal route. I did try for a couple of days but it was not working as expected so, in order to post the fix, I went for the easy route and patched my extracted DSDT instead; I'll try and revisit this soon.

This works for my E7470 with F11 and F12

Just add the following Rename of BRT6 and SSDT-BRT6.aml. Of course will still need the 2 renames of _OSI and OSID

Note: Only work with VoodooPS2Controller.kext, doesn't work with ApplePS2Controller that I normally use.

This works without Darwin injection and check? Because I had tried that exactly + the additional Darwin injection and it did not work. But I did not rename _OSI and OSID...

Sorry, I forgot to mentioned the following as well, I didn't include it because you already have it in your bootpack.

You'll need both SSDT-XOSI.aml & SSDT-BRT6.aml (attached above) and the following 3 rename patches: OSID -> XSID, _OSI ->XOSI, BRT6,2 -> BRTX,2
