No one is stopping by, so for the records:
I flashed the 694D pro2 bios.
It seems it can better handle two tualatins (with adapters).
I can logon WinXP but it takes forever.
Reinstall a OS results in I/O and various other errors.
I think it is because pro and pro2 have different southbridge.

Maybe, if the portion of the bios that handles the two CPUs could be copied over the pro bios (or the pro southbridge portion ove the pro2), there would be an improvement.
Having a programmer I can do any type of experiments.
But I have no bios modding expertise.

That's not correct - I was here, read your post and searched for a newer BIOS, but didn't found one and therefor didn't post. 😀

The problem is that if a beta BIOS existed, it will be hard to find and maybe it's lost forever because MSI deleted all this stuff on their backend servers (no public server) many years ago...I could rescue a few of these beta BIOSes (-> https://soggi.org/motherboards/msi.htm), but my contact wouldn't give me a complete backup and didn't make one on his own. I often got the answer "You're some years to late, this model's BIOSes have been deleted.".

The Pentium III 1.26GHz-S is 0.13 micron process (cpu-world) and according to MSI in 2002, neither 694D Pro (6321), Pro2 (6321+V2) or the 694D Master(6362) properly support 0.13um Tualatin CPU's.

Thank you.
I know.
As stated in my first post, I am using modified Tualatin-S and/or adapters, of course.

So, the pro2 perfectly works with the mentioned chips.
The “pro” does not.
The similarities and differences (minimal) between the two motherboards make me think what I wrote above.
So Probably a bios mod could help.

From their archives the Pro2 does not fully support tualatins, bios info (no mention):
https://web.archive.org/web/20020601221057/ht … el=MS-6321+V2.0
cpu support: https://web.archive.org/web/20020611060958/ht … el=MS-6321+V2.0
The 694T Pro Rev 5 does mention Tualatin support, but only Celerons: https://web.archive.org/web/20020602083037/ht … el=MS-6309+V5.0

Sorry but probably you are not reading my posts.
I am using modded chips or adapters…
You know that even 440bx motherboards work with Tualatin right?
I am a bit confused, I do not believe you do not know this so I am about to assume you are kidding me…

Thanks for trying.
Maybe someone with goodwill, spare time and bios modding expertise can do the trick of “mixing” pro and pro2 bioses.

I did some basic BIOS modding (with Modbin, AMIBCP, BIOS Patcher and stuff) in the past but that's not enough for this. Maybe it's just necessary to mod the latest Tualatin microcode updates into the latest 694D Pro BIOS!? You also can try to extract the microcode module with CBROM from the Pro2 BIOS and replace the one in the Pro BIOS. If this doesn't work, I don't know...

Yes I read your info about modding the cpu or a modded adapter for voltage and pin isolation.
Yes you can generally run a tualatin on most single cpu motherboards that support P3's as long as the Vreg can supply the lower voltages or have an adapter Vreg.
Maybe you could ask Turrican (if he was still active, gone since Sept. 2014) what all he did to get it to run with both cpu's, doubt it was just a pin mod.
My guess is he also did a bios mod as soggi suggests. Most dual boards don't like it when the cpu id's are not in their code or do not match each other. Is probably why you can run one but not both. Just a thought....

Ok,

This motherboard has problems… Or it is me.

After sone tryouts with modded bioses given by an angel of this forum, I gave up with Tualatins and reverted to standard 3.7 bios.

Problem is that this motherboard won’t work with ANY processor in socket2 !!
I tried two 933 and two 1000 coppermine-T.
It won’t even boot.
At least with the two Tualatin with LinLin adapter I saw the post.
Now nothing….

Of course I inverted the CPUs, of course I tested them on another motherboard just in case I fried one (or 2 or all 4)

Fiddling with the jumpers I was able to make it post with 66Mhz FSB….
In that state I could install windows2000 and only on ATA66 port.
Forget the Promise lite controller, it hangs during installation.

What is going on here?
Bad capacitors again??

well, the board is already famous for using bad quality capacitor (or i should say: cr*p) and they always failed after 2 or 3 year in service anyways.
So the question is: did you recap the whole board yet?

To be honest I recapped the capacitors that appeared to be damaged and fixed the design flaw on one of them (it was mounted with inverted polarity).

oh, the one mount between pci slot 😁

but i think you should at least replace all the cap in the VRM section of the board, when you see one of those cap going to birth, the other may follow soon.

better, can you provide us the current picture of the board?

Thank you for your interest.
Here some pictures

There is an IC in D12 position (under cpu1) that gets incredibly hot.
I do not know if it is an indication of something.

this capacitor look like it had been knocked out of the pad, can you made sure that is just some dust?

it possible that something is shorted, i don't think those IC (i don't remember seeing IC under the cpu socket tho.) should get that hot.

Sorry,
I mean “near”, not “under”…
South of the cpu1.
