UEFITool VS grub-mod-setup_var

Open 1 E7250A24 -- 1 System BIOS with BIOS Guard vA.24.bin file with UEFITool

UEFIPatch from LongSoft's GitHub A UEFI patchtool built on the older UEFITool engine. UEFITool is not needed for this patch, only the UEFIPatch applcation.

Download UEFITool from https://github.com/LongSoft/UEFITool/releases for example UEFITool_NE_A66_win32.zip is hidden behind the show all assets button

There's a discussion here about this being done successfully on a ThinkPad T460 with a SPI programmer and UEFITool. The same method should apply to the T460p.

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).

How to view proprietary blobs on your system

I have been a long ThinkPad user and have bought an XPS 13 for the first time. I changed my boot logo on my machines before using this tool following this guide.

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/
