Coreboot specs

Intel

xxx0: gm45 bridge, Montevina: no FSP, no ME: X200, T400, T500, R500, X300 : no QubesOS support there (no proper vt-d2)
xx20: Sandy bridge, no FSP. ME<10: BUP module required only: X220/T420/T520
xx30: Ivy bridge, no FSP. ME<10: ROMP and BUP required: X230/T430/W530 Z220 CMT and others

Additional required Intel blobs:

FSP is present in all Broadwell+ platforms

ME status on different boards models

Removed in ME <=6 (xxx0)
Deactivated+Neutered ME in ME 6 <= 10 (xx20 BUP/xx30 BUP+ROMP)
Deactivate+Partially Neutered (BUP, RBE, Kernel and syslibs modules REQUIRED in ME > 11)
Soft disable/HAP disable bit possible on ME 12+ (PoC BE CAUTIOUS)

xx30, xx20: ME 6 <= 10
Skylake, Kabylake, Whiskeylake and newer: ME >= 11
Intel ME then changed its name to Converged Security Management Engine (CSME), where HAP bit can be flipped, but modules cannot be removed anymore.

t430: @flawedworld is the owner of the current PR and is the one that actually owns a T430.

[flawedworld]

@tlaurion happy with the T430, I also have an X230

[techge]

Actually, I only have two x220 here. Unfortunately, I do not have a T420.

[MrChromebox]

I have:

• Librem 13v2
• Librem 13v4
• Librem 15v3
• Librem 15v4
• x230

[ThePlexus]

x230 and x220 here. Im also waiting for when we roll to next coreboot version to maintain/support p8h61m-pro desktop

[Tonux599]

Happy with kgpe-d16, will be purchasing an additional SPI chip for testing soon as its my main workhorse. Also have an x220 and a FHD modded x230.

[Thrilleratplay]

I have a dedicated x230 tablet for heads.

Additionally, I have:

• T430
• X220
• X220T
• X230 loose motherboards

and a Carbon X1 Gen1 but haven't have success flashing coreboot on it.

My main machine is a X230 with Nitrocaster FHD mod but that has a fully encrypted drive.

[MrChromebox]

Librem 13v4 (skylake): @MrChromebox
Librem 15v4 (skylake): @MrChromebox

those two boards are Kabylake, not skylake

[tlaurion]

@MrChromebox @Thrilleratplay OP modified. Thanks

[Thrilleratplay]

@tlaurion Can you remove the X1 Carbon Gen 1 from my name. Until I can successfully coreboot it, I will not be able to provide any assistant with it and do not want to create any confusion.

On CBFS region, neutering ME, expending BIOS region in IFD after having reduced ME region

[bwachter]

I'm mainly on the x230 (with several of them). I have a t430 which I'm currently not flashing due to initial setup issues trying to get to a working version - I do have a spare t430 board+CPU, though, but I need to get my hands on a fan for it first. After that it'd be usable for testing with an external display.
