@Lost_N_BIOS - Hehe, I would love a modded 2503 WiFi ver if possible

I just tried 2503 and so far no issues.

@howiec - OK, I will redo/update both now while I'm here, I'm sure everyone will want update anyway so might as well
--------------------

@ColonelStrike @jeffrds @redf0x @levski @Main Fighter @royal @howiec
Here is both WIFI AC & Non-WIFI update mod BIOS 2503 - Flash via USB Flashback ONLY, this is stock modified BIOS!!!

*** Both models included in below link, be sure to pick correct one per your model or flash will (should) fail
http://s000.tinyupload.com/index.php?fil...452132424016517

USB Flashback names for both boards >>
Non-Wifi = M10H.CAP
Wifi AC = M10HWIFI.CAP

Awesome, you're the best!

Will try shortly.

@howiec - You're welcome! Yes, please post back and let me know if all is OK (should be fine )

@Lost_N_BIOS - Running the 2503 WiFi pre-Spectre/Meltdown version with no issues thus far on my 8700k!

Nice work!

@howiec - Great to hear it, thanks for the quick test and report back!

Hello, i need modded bios of older Version 1602 2018/07/10

I can find IOAPIC 24-119 now
I remember that there must be HPET option, but i can't find it right now.

I need:
1. HPET option
2. TCO Timer
3. IOAPIC 24-119
4. XHCI Legacy
5. XHCI Hand-off
6. USB KB/Mouse Sim
7. SPD Write Disable
8. CPU SMM submenu (ALL inner contents)
9. Legacy IO Low Latency
10. And Memory Remap (single option)

-CPU Microcode WITHOUT Meltdown & Spectre patches for full CPU performance, looks like version 1602 has no M&S code, is that correct?

I need 2 versions of modded bios, first version with INTEL ME disabled and 2nd version with enabled ME.
My cpu is 8700k
My mobo is Asus X Hero z370 wifi, but i've pulled out wifi module.

Also, what method are you using to dissable ME, is it partially neutralized or fully disabled?

I know that code in the ROM cannot be removed because it’s inside of the processor itself (read only memory). But other part is on the flash, and it can be removed.
How to check total amount of ME code remaining after your modification?

Send me pm with your pp email and how much to donate.

Thank you Sir!

@REGEN - Why do you need OLD BIOS?? If you just want non-spectre/meltdown microcodes we can do that via swap in >> cpu906EA_plat02_ver00000070_2017-08-23_PRD_711B866C.bin
No, 1602 BIOS is not pre-spectre/meltdown, it has some fixes there in microcodes at least, the one above is only one for 906EA without some fix in it (1602 has Rev 96 from 5/2/2018)

ME Disabled, if you wanted, I would do via HAP Bit disable. How are you flashing BIOS? I don't think USB Flashback will flash in ME FW if your ME FW is already that version, so it will skip any ME FW changes.
You may have to flash that is via ME FW update tool, to disable, but to enable back you would then need flash programmer, or unlocked FD via flash programmer or pinmod.
So, before, you, or I, do anything in regards to ME FW, be 100% sure of what you want, it's not easy to go back if you do not have flash programmer or already did pimod (live short) and unlocked your FD

Also, in regards to ME FW, if you've already flashed latest BIOS, you cannot go back to older ME FW, unless unlocked FD already or you have flash programmer.
But you can flash in disable ME FW via ME FW update tool

Never mind! Disregard most of what I mentioned above, if you want ME FW disabled by me using HAP Bit method, you need flash programmer or unlocked FD first, because FD and ME region both need written to to disable ME FW in this manner
I have no idea about ME FW workings, or the things you asked about, you'll have to research about what HAP bit disable ME FW gives you and then you know what I can do for you via this method (once you have unlocked FD, or flash programmer such as CH341A)

If your goal is about performance, then leave ME FW alone. And use latest BIOS + Old microcode that you want.
So let me know what you want done, I can edit the latest mod I already did for you if you want, to put in older microcode (Actually, that would be post #77 above)
if you want ME FW changed in that BIOS, or you still want OLD BIOS, let me know.

I will send you PM, if you really want, but it's not required for me to edit something for you.
Send me a PM if you still want to send something my way and I'll send you how-to info, thanks!

1. I overclocked my cpu to 4.7ghz on 1602 bios and it is working fine for 2 years with two gtx 1080 ti in SLI.
I watched few videos on youtube where 2017 bioses for z370 taichi are faster than latest 2020. Anyway, I need to test it.

2. What microcode without M&S can you recommend?

3. Yes I know about HAP Bit disable, but also, it is possible to delete part of the ME code from the flash.

4. Yes I want to test one mobo with ME disabled. If there will be problems with stability or overclocking, I will use my friends help, he has flash programmer.

5. I don't know what microcode to choose, but as I said, I need best overclocking + disabled ME + no M&S

6. For best results, again, we need to test, so I have 2 same mobos with same cpu.
They have the same 1602 bios. On number one I will flash 1602 with ME, on other 1602 without it.
If I will have problems, I will wirte here and then maybe try nevest bios. Or best one for overclocking. Maybe you can comment what bios is the best for your taste?

Reason to use latest bios if older one is working stable? I won't upgrade to 9900k.

Thank you a lot!

Ok then, please tell me, you can't help me, so I need to search for another solution?

@REGEN - Sorry for delay, I am always buried and behind here, can't keep up with all the new requests each day
1. So, your CPU would OC fine on latest BIOS too, but if you want old BIOS we can do. Taichi BIOS or board is unrelated to yours, but yes, sometimes old BIOS (due to ME or microcodes, or both) may be faster

2. I mentioned it above.
3. If you want me to do it, I only do HAP bit disable.
4. See above, I can do one w/ one w/out, but yes, you will need flash programmer to go back to one with once it's disabled (Unless you flash in unlocked FD first, via pinmod or flash programmer)
5. See #2

6. Great way to test

I don't use this board, so I can't comment on what BIOS is best for anything, other than to say I always suggest using the latest BIOS and then mod to whatever you want done (such as ME Disable, old microcodes etc)
This way, you're using the latest BIOS with all the bugs worked out, and all proper fixes and enhancements added in vs some old buggy BIOS that may not be tuned for best performance (speaking generally, nothing to do about microcodes)

Ok. Since, I already downloaded new modded bios, I will have 3 different biosses and 2 same mobos to test.
But first I need old version modded bios 1602. Tell me when it's ready.

Thank you!

Happy New Year!

It's not even Christmas yet
Happy Holidays and New Year to you as well! Sorry for delay here, always buried

This is my bad sense of humor. I just come here from time to time and check, maybe the BIOS is READY. hands itch to test)))))
