SSDTTime VS grub-mod-setup_var

Build SSDT-EC, SSDT-USBX, SSDT-XOSI, SSDT-PLUG, and SSDT-HPET from SSDTTime instead of manually https://github.com/corpnewt/SSDTTime

I'm trying to do a fresh install of Ventura. I tried using SSDTTime from my Catalina at first, only to discover that the option to dump DSDT is disabled by design because that'll not give me the unadulterated DSDT which makes sense.

Precisely, I went through the guide once more, discovered some new tools (like USBToolBox for example) then I did USB mapping + SSDTs (using SSDTTime) by hand (I was not sure that I did them properly in the first place, 3 years ago). Then with those clean SSDTs & kext, I used my old EFI and OCAT to merge everything together. Double checked everything at the end just to be sure that I did not forget a thing and that OCAT did not mess up anything.

I couldn't get past this point in mine without running https://github.com/corpnewt/SSDTTime and enabling `SetupVirtualMap` in Booter Quirks

It's a must though. Every PC is different, even 2 identical models might not have the same ACPI tables.. I would Start here.. There's only a few things you'll really need, especially on these machines. While there's many methods, a clean install of windows NOT booted through OpenCore, using SSDTime is the easiest for most.

I built my own SSDTs using SSDTTime.

OpenCore 0.8.7 / Dumping DSDT use SSDTTime for generate ACPI Tables / Use genSMBIOS for generate MLB (Board Serial), ROM (Mac Address), SystemSerialNumber (Serial), SystemUUID (SmUUID)

try mapping usb drive on windows first using USBToolBox as USBInjectAll isn't fully working anymore on Monterey. Also I suggest creating your own SSDT/acpi patches via SSDTTime.

If so, switch back to AppleALC and add SSDT-HPET.aml with the patches in the patches.plist generated in SSDTTime (https://github.com/corpnewt/SSDTTime).

If HPET is not an option in firmware, then it is disabled (0x00) and hidden from you. Which in practice is bad. The only option for users in this case is to download your firmware from the vendor, use this tool to locate the register and set the value with this tool to enabled (0x01).

And you can do all the same things with this(https://github.com/datasone/grub-mod-setup_var), but it doesn't have a UI, so less convenient.

It is possible with a little bios edit. I did it with my old asus which I dont have anymore. All You have to do is follow this guide: https://www.reddit.com/r/Lenovo/comments/id0457/guide_to_reenable_undervolting_after_latest_bios/?utm_source=share&utm_medium=ios_app&utm_name=iossmf thing I did different is use https://github.com/datasone/grub-mod-setup_var/releases instead of RU.efi to boot my usb I sont remember why tho

You neaed to download setup_var

Download this file and place it inside BOOT

explanation: this is where maxdarksol begins skimping on explanation. download the efi file here. It's called modGRUBShell.efi instead of bootx64.efi. It doesn't matter, it's just a file name. Get a usb thumb drive, format it as FAT32. Open it and make a folder called "efi". Then in it another folder called "boot". Then put the modGRUBShell.efi file in it.

The efi file (modGRUBShell.efi) from release 1.3+ from https://github.com/datasone/grub-mod-setup_var/releases

Download the .efi from here and place it in the Tools folder of OpenCore, create a new snapshot in ProperTree or add it manually to the tools section in the config.

download https://github.com/datasone/grub-mod-setup_var/releases/download/1.3/modGRUBShell.efi and put in the EFI\BOOT folder in the USB pen and rename it as bootx64.efi .

I did this by using the Grub bootloader patched with setup_var (https://github.com/datasone/grub-mod-setup_var). Follow this guide to obtain the correct IFR values for setup: http://forum.notebookreview.com/threads/tutorial-xps-15-9550-9550-bios-advanced-options.810307/
