Now, that's not a "normal" Coppermine, but a Coppermine-T. IIRC the "-T" denoted that it used the same signalling levels as the Tualatin, probably ment for using a cheaper CPU in a Tualatin motherboard, IDK.

Did OP state that it was an SL5QE in question? I can't seem to see any sSpec mentioned

No sspec mentioned but it was the only slot1 I found.

OP still hasn't posted a pic of the cpu

We're talking about microcode...

OP if you're brave enough to try, I extracted the microcode file from SAH6_YW.BIN

I haven't found out what CPUID that is.
I looked. Doesn't seem to be a P2, ppro, or Celeron. Possibly an engineering sample chip?

I can't say I recommend you try it.

Up to you.

While we're here is it possible by any chance to mod the microcode for SP as well? Curious to see if it'll help at all with my BH6 1.1 and a SL5QV (cD0) that would POST but always hangs during the Windows 98 install. The BH6 is my test board so I don't mind trying it out.

Update: the 933 Slot 1 CPU arrived. Came with a monstrous aftermarket heatsink that made it nearly impossible to plug in the power supply, but it actually booted up! Runs at 700MHz natch, haven’t tried to overclock it or boot Windows. It seems that indeed, the 866 CPU is broken or fried in some way.

I may get a different mobo anyway in case something bad happens here, and will definitely get some PC133 RAM to see how far I can overclock it on this old board, but for now I’m just glad to know it worked!

I have my bases covered for almost everything about the board when/if I want to overclock it, except the AGP slot. Running at 133MHz would make that slot run at roughly 90MHz, and I know many AGP graphics cards don’t like that. I have a GeForce MX-4000 plugged in there right now, would it be able to handle that speed since it’s a couple years removed from this era?

I never had a BX motherboard back then, but I did have a KT 333 board that I overclocked to 209 (209/4 = 52.5 PCI x 2 = 104.5) and my Ti4200 never had an issue. I only replaced it with an 8RDA3+ because I opened my case one day and saw that the caps were bulging.

Good to hear.
If you have a multimeter and want to see if you can figure it out, try testing all the components on the CPU board.
It could simply be one of the resistor arrays, or a cap.
Resistors should read around 56k Ohm from memory.
Caps should not be short.

Sunkindly: sure. It only takes 5 mins since I put the instructions up.

Update: the 933 Slot 1 CPU arrived. Came with a monstrous aftermarket heatsink that made it nearly impossible to plug in the power supply, but it actually booted up! Runs at 700MHz natch, haven’t tried to overclock it or boot Windows. It seems that indeed, the 866 CPU is broken or fried in some way.

I may get a different mobo anyway in case something bad happens here, and will definitely get some PC133 RAM to see how far I can overclock it on this old board, but for now I’m just glad to know it worked!

That's great news, hopefully all goes smoothly OS-wise!

Thanks so much!

You're welcome.
Keen to hear how it goes - I hope you have a spare bios to hotflash it to.

There is a project that collects microcodes.
https://github.com/platomav/CPUMicrocodes/tree/master/Intel
CPUCODE.BIN - I have updated all the expired ones.
tools
-bit - It disassembles Award BIOS into modules well and shows CPU microcodes.
-MCE - Checks the microcode against the GitHub database. For Award BIOS, you must provide an uncompressed microcode file.

Which one is in that pic?
I only randomly picked a slot 1 abit board that supported tualatins, so there might be newer ones out there.

Update: the 933 Slot 1 CPU arrived. Came with a monstrous aftermarket heatsink that made it nearly impossible to plug in the power supply, but it actually booted up! Runs at 700MHz natch, haven’t tried to overclock it or boot Windows. It seems that indeed, the 866 CPU is broken or fried in some way.

I may get a different mobo anyway in case something bad happens here, and will definitely get some PC133 RAM to see how far I can overclock it on this old board, but for now I’m just glad to know it worked!

Great news!

Did you ever post a picture of the 866, or mentioned the sspec? Would be interesting to know if it actually was a Coppermine-T?

[Edit] Seems Coppermine-T wasn't made in Slot-1, so probably not that. But still interesting, though.

I'm assuming it's this one since it's the only Slot 1 866MHz rated at 1.7V...but I don't see anything peculiar about it:
https://www.cpu-world.com/sspec/SL/SL4BV.html

I'm kinda curious if the working 933MHz CPU is SL448 (cB0) or SL4BV (cC0)...they're both 1.7V so that rules out the earlier discussion about voltage potentially being an issue...

Any motherboard with an Award BIOS.
This screenshot is from the MСE utility.

bit.exe bios.bin
Get uncompressed CPUCODE.BIN
then
mce.exe CPUCODE.BIN

PS https://github.com/platomav/MCExtractor
In beginning, they do exe-file, no its Pyton script.

ok, so which bios is in the pic?
