thinkpad-firmware-patches VS coreboot

"skyra1n" ThinkPad Firmware Patches from digmorepaka's GitHub a list of UEFI patches for ThinkPads, these are the special sauce for adding features to our BIOS. If you have a ThinkPad 30 series device, you do not need to follow this guide for flashing skyra1n, you can flash your BIOS with the internal flashing software.

I bios unlocked and enabled the custom undervolt menu on 1.44 bios using a ch341 bios programmer. This way I set the undervolt via the bios rather than throttlestop.

Hey guys! Have any one tried this BIOS mod on latest firmware?

Here's the link to the uefi patches which are used to unlock the bios. https://github.com/digmorepaka/thinkpad-firmware-patches There's a very short and undetailed guide how to apply the patches to your bios. But just know that you need an external bios programmer like ch341a

First thing is to verify that the thunderbolt firmware is up to date and that both ports are working. Start here https://pcsupport.lenovo.com/br/en/solutions/ht508988. Then, if you want, you can buy these two and use these equipment (Ams1117 3.3v ) > aliexpress.com/item/32838236408.html with my ch341a > aliexpress.com/item/32841448145.html to make the bios mod (this will work for cards of wifi better wifi 6 and hackintosh) the patches are here (https://github.com/digmorepaka/thinkpad-firmware-patches), (it is possible to clean the intel ME) too, if you can't do it, don't risk it, ask help here in the community. I suggest backing up your bios and also the thunderbolt bios. Here is another topic from a colleague in the community and in it there is a pdf of mine where to check the cfg-lock to enable or disable.

You can try flash this bios mod to remove the whitelist. https://github.com/digmorepaka/thinkpad-firmware-patches

Pretty sure the whitelist for wifi is long gone, if not, there's always patches. Not for newbs admittedly.

Why BIOS (did you mean UEFI?) when it runs the best boot loader, which is Coreboot¹. Many users would love to re-flash their bios/uefi for it, if it’s supported.

Coreboot is 0.6% C++.

NovaCustom ; some models come with Dasharo a coreboot distribution.

You can also use Mr. Chromebox Script to install Coreboot on your chromebook to get a UEFI BIOS on your Chromebook and then you can go an install either a linux distro or even Windows if you want. It's a pretty straightforward process and also reversable if you want to go back to just using ChromeOS.

Some models are available with Dasharo a [coreboot]https://www.coreboot.org/) distribution.

why no haswell_ult_dmi_registers for broadwell? in https://github.com/coreboot/coreboot/blob/master/util/inteltool/pcie.c

use croshfirmware.sh from https://github.com/coreboot/coreboot/tree/master/util/chromeos

There may be other protections to restrict SPI flash access for security reasons (so you might not be able to flash your custom firmware in the OS), but worst case you can use a HW flasher (or maybe USB flashback). Still, this doesn't address the elephant in the room - platform initialization code might be open-sourced, but that isn't everything. You'll still need to figure out the board-specific stuff (the Super I/O chip, chipset GPIOs, other peripherals, etc.). Using coreboot as an example, Intel provides the Firmware Support Package blob to handle platform initialization. I think AGESA is somewhat similar to this, though Intel publicly releases the binaries for use in coreboot/etc. Thanks to the FSP, coreboot has support for recent Intel chipsets. However, there is only support for two recent consumer boards: the MSI PRO Z690-A WiFi DDR4 and DDR5.

does anyone know what is https://github.com/coreboot/coreboot/blob/b12caef23bc1b29c2e658f2b728cc4beac1e62b9/src/northbridge/intel/haswell/vcu_mailbox.c
