OC DELL Latitude E6420

... -update-: check posts following

The only thing left thats Rehabmans now is ... Debugging where would the world be without debugging..

Things youll encounter at first where you have to use a (FakeSMC.kext) Driver Arrangement: Fakesmc, Usbinjectall, ahci_port_injector, and Inject nVidia, Fix RTC, or a LegacyRTC.kext is when you boot verbose... or plug in usb things like that the Clover EFI will RED-CONSOLE-PANIC: once you get working ACPI Tables it will stop that alltogether... we also need to ProvideConsoleGop(); -> XNU Verbose Console....

Quirks Section: There are none, you can-should uncheck all these...

Theres no Page for Sandybridge... I use a laptop so... : Dell Latitude E6520 nVidia Working.. I can edit this like a OP: Originally was using FakeSMC+Plugins, Now am using VirtualSMC and its working just fine for me..

So upon first boot : LocalAPIC Processor = Disabled you need to modify your APIC.aml table and remove the CPUS that macOS isnt using for power management....

and they wont show up as a CPU or that theres one thats Disabled...

Persistent Bug: Mouse Cursor (Previous Selector artifacting the Permanent Cursor) as it moves so its moving as its previously selected Bitmap such as a Text Indicator causing you to click as a text indicator on a button for example and thats wrong its click as an Arrow on the button....

The actual EFI: Clover{Duet,REFIT,OpenCore Library Extensions} - When booting in EFI Mode it keeps trying to Enter Boot-Args... , The Mouse and HFS and Audio Driver Work..... the point in this area is it doesnt support its protocols completely... not that its not UEFI it just is lacking a subset probably.. not a SuperSet..

The Model Emulated: uses MacbookPro 8,1.. may switch to MacbookPro8,3

Fixing the DSDT/SSDT Tables: it mainly involves consolidating instructural based asl, with syntaxtual equivalent so a little bit of algebra is required..

The Point: to use the least amount of tickboxes..... and have it working at the bare minimum with a how to what for this specific SandyBridge

Board...

Fix KEXT Stall Error: NVHDA Stalls.. use AppleALC 1.2.8 or youll be booting for 15 Minutes per restart this ones five seconds....

This is the EDID:

EDID: 00ff ffff ffff ff00 30e4 d902 0000 0000 0014 0104 9022 1378 0a15 d59e 5950 9826 0e50 5400 0000 0101 0101 0101 0101 0101 0101 0101 0101 7e36 80b0 7038 1f40 3020 3500 58c2 1000 0018 5424 80b0 7038 1f40 3020 3500 58c2 1000 0018 0000 00fe 004d 4336 4a4e 8131 3536 5746 310a 0000 0000 0000 4131 9e00 0000 0002 010a 2020 0030

The ALC_ID=12

Fix USB: Inject Device IDS into the Root Controllers...

DSDT/SSDT Headers and Normalization: MCFG , DMAR I Assume like DSDT/SSDT2 you have to change it to APPLE Properties..

Fix your RTC and IRQs these you have to do by hand and go ok so if these two conflict here it should leave IRQ2 Open when your done.. the only

required Spare IRQ... conflict so that each device has one.......

;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

OpenCore: is a different thing altogether <-

debug debug debug : Developers! Developers! Developers! <Prologue> so config.plist not present in vault .. yes im using x86legacy vault "SecureBoot" and.. probably the same FSB Error.... My vaults fixed and is booting ...

Tables K Done : Signatures: Recalculate these as they may be wrong..

SSDT-1 : TPM : U1NETA==
SSDT-2 : CPU0IST : U1NETA==
SSDT-3 : CpuPm : U1NETA==
SSDT-4 : NvdTabl : U1NETA==
APIC : CBX3 : QVBJQw==
MCFG : SNDYBRDG : TUNGRw==
DMAR: SNB : RE1BUg==
DSDT : SYSFexxx : RFNETA==

TableIDs:
SSDT-1 : VFBNIICAgICA=
SSDT-2 : Q3B1MElzdCA=
SSDT-3 : Q3B1UG0gICAg
SSDT-4 : TnZkVGFibCA
APIC : Q0JYMyAgIA==
MCFG : U05EWUJSREc=
DMAR : U05CICAgICA=
DSDT : U1lTRmV4eHg=

So we have just out of Resources error to figure out..

Figure out why it can't get the CPU FSB...

Figure out why when you press the Restore DMG does it not do anything...

CPU Does not Support RDRAND... or AVX2.... Monterand and Surplus

Required? .... your P C States down... theres like 19 P States and 4 C States I think 0 2 4 6 7

So tables to drop: CPU0IST, MCFG, CPUPM.... The correct way for CStates

is the original Snow Leopard Method, 0xE2 MSR Unlock isnt required

which is odd mine was always failing if i didnt patch AICPM but

when the SSDT is done correctly it wont require that... so drop SSDT.aml....

<your_favourite_drum_and_bass></goes_here>

Im like just cruising on up right behind!

So filevault works... , now just to work backwards and back around <-

1.thisll be required eventually..

get very meticulous and start disabling everything

"Whatever You guys decide on doing:

APFS and HFS Plus detection errors just -1 on the Date..

1:02

1:27 whos not?

BIOS Modding: so wants to change BIOS Logo to Phoenix as we use Phoenix Bioses is Bridge Pin 5 and 9 on the IDT Audio Codec Chip its on the Right and Top of the Motherboard counting UP from the bottom right hand side.. Make sure to use All_Regions_Bios File Dump... I have the utility for it.. I wont do anything else because i dont have a FLASH CLIP.... and blew all 2 opportunities so i only have the 17" Dell left the E6520 i just blew 2 E6420s in a Fire.. they both caught fire... So I now know my precautions for the Finale~ is just simply locate my M.8 8mm screws and those are the only ones i need if you use anything different welcome a fire and a shorted laptop motherboard... But beside the point so Something Something APFS is the Loading Bar Issue where the Loading Bar doesnt show up? As I HAVE gotten some kind of Verbose Output from OpenCore?... and Remember im starting from the Bare Minimum just working my way up.. so Maybe needs APFSLegacy Efi Driver and it MIGHT not support Loading DMGs... I do not know.. Bios Modding: in UEFI Tool the FULL DUMP of the BIOS you'll know you have it when its like 9MB and Loads as Intel_Image... if you flash just its bios descriptor itll Brick the Laptop and whether theres a persistent SATA Bug after "Just the DVD Drive" i also dont know i couldnt plug in my DVD Drive leading me to think it was bricked but it wasnt.. But like the ones who found this means: Does this open the door for doing things they claim No Dell has Ever Intended *YES: Overclocking/Voltage-Adjustments Fan Adjustments...
