I am struggling to make Northwood chips run on any of my 775 boards and at this point I ran out of options as to why.
The boards that I tried: P5B-Deluxe, Commando, P5E3-Premium
Chips that I tried: 2.4B (D1), 2.8C (M0), 3.0C (D1)
On each board that I tried, I injected the microcode corresponding to desired Northwood CPUID into the BIOS.
I've also pin-modded the 775-478 adapter to get rid of the "new CPU detected" error on each boot.
Finally, I've modded one of the boards (P5B-Deluxe) to make sure it supplies CPU with sufficient Vcore (1.5V) on POST.
Still, I'm always getting either code 00 or 01 on POST.
The same setup seems to be working fine with Prescott 478 chips.
Is there anything really dumb/obvious that I am missing?

None that I can see.
What an odd issue.

Those should work in the Commando and the P5B try the Commando with the second release bios.
I woudnt be sure about the 2.4B working in the P5E3 being a 133 bus chip but they all should work in the Commando I do remember something now about the early Bios.

Sounds like a similar thing to what I had with my 775 board (DFI Infinity P965-S Dark). It literally has two different BIOS files for it to run either older or newer 775 chips.
Depending on what you have is what you'd need flashed in for it to work. |

Tried Commando BIOS 0702. Injected microcodes. Getting code 87 on POST now.
I am starting to suspect that my model of adapter may not be working with Northwoods, for whatever reason.

Well that could be something they are only cheap chinese made.
Antinomy was knowledgable with them he might have an answer to it.

To guys who got Northwoods working - how did you inject Northwood support into the BIOS?
I am using software called MMTool. Used it to extract the 0F25 (M0) and 0F29 (D1) microcodes from P4C800-E Deluxe and P5LD2-X BIOSes (0F25 comes in two versions, with platform types 04 and 10) and then use the same tool to add them to the target BIOS. I tried both adding the new microcodes at the end of the list, as well as placing them just ahead of the Prescott ones (in case the board goes through Microcodes in some sort of an order) while preserving the total amount and size taken by microcodes by deleting some Prescott2M/Smithfield ones. Perhaps there is another tool that actually works?

What version of MMTool?
v3.26 works.

I used version "3.22_1B_21Fix-BKMOD".
I just gave 3.26 a try but it seems buggy. None of the Microcodes extracted by 3.26 can be imported by either itself or 3.22. And if I import or delete a Microcode, it seems to randomly set other Microcodes to 0000 hex values.

Northwood works fine on 915-975X boards. Starting from P965 doesn't POST, didn't figure out a fix. Also, P5B Deluxe works fine with s478 Prescott but P5K doesn't, maybe wiped out support too. It's not a VID issue.
Try P5WD2 Dlx/Prem - works fine with Northwood. In general, you should look for board supporting Pentium XE 3.4GHz, Pentium XE 3.46 GHz - these are Gallatin CPUs and Gallatin is the same as Northwood M0 with L3 cache disabled. Anything that works with Gallatin will work with Northwood.
Semyon, microcodes don't help in this case, don't waste your time. It's more low-level.

Of course it's possible - GRIFF even got a Pentium M running on P5B dlx. As I said, it's most likely a BIOS mod. I think it's either bootblock or main module (1B). The reason I'm sure is because after a certain BIOS version Northwood doesn't work on 975X. But hardware mod is another possible reason. Another thing to consider is Vtt. For Northwood 478 it's around Vcore I think, 1.55V. For 775 it's 1.3 and below. Might be it. But I think BIOS is more important to crack. Hex workshop, IDA and MMTool should be your friends.
Another thing to consider is that before this wytiwyx managed to run Core2 CPUs on 915-925 boards which requires quite sophisticated BIOS modding and some hardware mods. With that background cracking Northwood had to be pretty easy for him.

Couldn't run Northwood even on 775 boards but to tell the truth, haven't tryed too hard.  My Biostar G31-m4 running like a charm though. It's close to a socket adapter and a 775 board combo. |

Yep, I've got that board. Didn't test though |

Hey guys, I'm just getting back to this now myself. I can get the only E0 800FSB Prescott I have to boot in my P35C-DS3R pretty easily without any modifications outside of the VSS mods for voltage, every other CPU however is an issue and I am yet to try and inject microcodes into the bios since it seems to be a more painful ordeal than it is on AMI BIOS's.
Now I had a quick go on my rex and I get stuck at the bios post screen with the same Prescott CPU, however the error it comes up with is 3A which is a mem issue. This seems consistent with the only small issue I had with my gigabyte board where I had to swap ram to get it working. Perhaps this is a place to start?

P5W-DH will run with Northwoods.

I probably have the bios you need already. Give me the exact model of your board and I'll hook you up.

That is mega! Thanks so much Scott! What microcodes does it have on it if I can ask? Just in case I plug in a CPU that isn't compatible and wonder why it doesn't work  |

Should be all of them including Xeon's.
Lemme know how it goes. No guaranty the board will like it, but the codes are in there.
