HP 8470P w/AMD Radeon GPU

[ssprod]

Greetings..

HP 8470P 

i5 3360 CPU

Radeon HD 7650M GPU

I've managed to get almost everything running well with the exception of WIFI. Purchased a Broadcom 43224 card, as I've used this with another 8470P w/iNtel GPU.. however it's not working in this system. Any thoughts would be much appreciated. Thanks.

Thanks Jake, still no positive results. Incidentally, the intel wifi card that I replaced had 3 leads connected to it 1-3. I'm presently connecting 1+2 to the Broadcom card.

Thanks, Jake.

Hmm Broadcom 43224 is just DW1520. You just need FakePCIID.kext + FakePCIID_Broadcom_WiFi.kext

If stil not working, then add Lilu.kext + AirportBrcmFixup.kext

All can go in /EFI/Clover/kexts/Other

Thanks again. I've re-installed High Sierra and still no change. The card is recognized in DPCI, but not showing up in OSX at all. These are my kexts currently in EFI/Clover/kexts/Other. 

Update: I reversed the leads on the wifi card, and it's working now with these kexts.  I'd be glad to post my EFI, however I seem to be limited to under 2megs for upload. Thanks Jake !
