Stepping P0 is ES cpu ?
Both: usual and ES. They use the same microcode.




Ok that's weird then because @mcduncan reports having successfully flashed and using an i9 9900T on 7060


Mine i9 9900T is R0, not P0.


Yes but that's still using 906EC microcode no ? @DeathBringer any thoughts on that ?

No, CPUs with stepping R0 has CPUID=0x906ED!

I've analysed this BIOS again.
Bad news - it blocks using all CPUs with stepping P0 (CPUID=0x906EC).
I can patch it but it's located in hashed volume (protected by BootGuard).



Does that means all the 906EC,P0 CPU cannot support? It's a pity, still thanks for you and @Sleinous great work

I can make a patch for it. But I'm not sure if it is safe because of BootGuard.

Check if boot guard enabled at PCH or not, if you have not checked yet, it may not have key burned into FPF. If not, then you can disable at ME FW side and carry on
MEINFOWin.exe -verbose

Check end of report, if you see Measured or Verified boot enabled at Left/FPF side then yes you cannot edit anything in boot guard covered area. I'm sure you know all this DeathBringer, just not sure if anyone looked at MEINFO report on these systems yet to confirm if FPF burned in or not

Bummer to see Well, I guess that shuts this down for other editing

Such a shame, but to be honest, apart from the ES cpus (which is a shame), 906EC doesn't include much of interest as most of the CPUs are unlocked multiplier K models and you really wouldn't get much overclocking headroom on these dell boards and next to no options in BIOS anyway :p

The only two CPUs that unfortunately won't be supported and aren't K models : i5 9400F,i5 9400
The F model has no integrated GPU so useless for a Micro PC but could be used in a SFF I guess with a low profile GPU.

Still a huge achievement and again thanks to both of you !

@Lost_N_BIOS
Did you know which program should I use for lzma-compressing to get the same result as in BIOS?
I've tried some version of lzma.exe (from LZMA SDK Igor Pavlov), but length of result does not match the BIOS.

OK. I need LzmaCompress based on LZMA Utility 18.05 by Igor Pavlov
or lzma.exe e -d24 -fb32 inputfile outputfile

Good luck DeathBringer! I've never seen it possible, but I've also never seen anyone try either. At least with programmer here they can recover easily!

Yeah i'm willing to test if needed but wouldn't be able to actually test the i9 9900T ES as I don't have one :)

You can test BIOS if brick or not, since you have programmer. So that would really be all that's needed to confirm, if working then I bet his CPU related edits will be OK

OK. Please make BIOS dump by your hardware programmer.

@DeathBringer - Just setting that up now for you, will upload asap :)
