From this list I've had bad experience with the Soltek board, not very stable, I don't recommend it.

I've ended up with a PIII-S 1266 modded by the Korean guy on a plain Intel D815EEA and it flies, but you know, only 512mb of ram and no overclock.

If you still don't have the cpu with you, I won't discard buting one of these modded cpus, as Coppermine 'only' boards that can support these Tualatins with a modded bios are way more varied and affordable!

I can have motherboard Shuttle AV18E2 3.1 for +-190eur. And PIII-S 1266 for 25eur. Or PIII-S 1400 for 75eur. In my eyes variant 1400 not cost for additional money versus variant 1266, what you mean?
I have to adopt myself and look around to know what is a reasonable price for what piece, because I've only been watching it for a few days, so I can't simply say what is an adequate price and what is already too much.

Thank you for link. And are here some models what are better? for example if I will be searching board with via chipset.
For example Shuttle AV18E2 3.1 I can have for affordable price. But I see that exist version 4.1 too, but I not find any information what is different between Shuttle AV18E2 3.1 and Shuttle AV18E2 4.1.

Better for what?

These boards are all very similar in terms of features and spec; what is 'best' depends on what you want to do. If DOS is your target, go for max # of ISA slots - but bear in mind that a Tualatin will be too fast for a lot of DOS stuff.

If DOS isn't relevant and you want Win98SE/ME, go for an i815, i820 or - better - SiS635T for best speed.

If you want Win2k/XP, you want more RAM than that and you're back with Via 694T , or more exotic things like i840 or Serverworks IIIHE.

I mean this cpu, which has an interposer installed to be used on (almost) any Coppermine board.

For me 190€ on a 23 year old board you don't really know its state it's way too much. I paid around 25€ for the D815EEA, at least in Spain it's still easy to find random P3 boards in second hand apps for such low price.
The only thing you need is a modded cpu (or mod it yourself) 😉

Check whether the boards you're looking at have official support for the more demanding CPUs, like the P3-S 1.4GHz/512KB.
The Shuttle AV18E2 boards don't officially support that CPU - only the 256KB chips are listed.
I have one of those boards but I still haven't tried it, so no idea whether the 512KB chips really cause any trouble or not. I'm guessing the onboard VRM wasn't built for the current draw.
If I ever put that system together, I'll try the 1.4GHz/512KB anyway, but if I ran it that way long term I'd try to keep things cool to help the VRM be happier.

FYI - I had to recap my AV18E2. The originals were OST/IQ brand. I don't know what other brands they might have used.

Of course, I also look at the prices. That's why I haven't selected a motherboard yet. Some boards that I would like are either completely unavailable or cost an incredible amount. Same reason why I'm thinking of buying the P3-S Tualatin 1266MHz 512 and not the 1400MHz 512. Because I can have the 1266MHz 512 version for a quarter of the price of the 1400MHz 512 version.

I would like to put together my first retro build in the coming weeks months. I have a little boy and I would like play with him games from childhood.
This is actually what brought me to this site. Of course, I have a current computer system, for work and playing current games Intel Xeon Sapphire Rapids 56 p-cores 112 threads ROG Strix 4090 OC 8channel memory etc. But I'd like to have a gaming station at home for older pieces as for example Heroes2/3/Quake2/Arena/HalfLife/2/DeusEx/NFS/2SE/Keen/GoldenAxe/etc. That feeling is not same when you playing on 4K IPS 160Hz with RTX 4090 if you understand. 😀

Thanks to all, very useful advices. I'm not an expert on very old chipsets so any info is great.
Hm so as novice I see that many of yours prefer these chipsets/motherboards as better:
VIA VT82C694T (Apollo Pro 133T): ABIT VH6T, QDI P6V694T/A10T, MSI 694T PRO, Soyo SY-7VBA133U
VIA VT8633 (Apollo Pro 266): ASUS CUV266 (DDR)
SiS 645T: ECS P6S5AT

Haha now you realise that problem with Tualatin builds are the motherboards not the CPUs themselves 🙁. Good luck on your search.

About processor, if will be variant 1400MHz many more expensive, so I have not problem buy cheaper 1266MHz variant.
Only what I not know, variant 1400MHz have more steppings, for example only on eBay exist more steppings for buy, is between these some big difference?

Today I receive offer for MSI 694T Pro Ver.5 where is wrote A6309MS MB5.0 V7.1 091901 is it good bios version for PIII-S 1400?
On website cpu-upgrade.com is information from some user that with last bios version PIII-S 1400 works
And on website theretroweb.com is wrote that for MSI 694T Pro Ver.5 is last bios version 071595 V7.5

Just to add some cheaper possibilities - there are some brand-name prebuilt systems/motherboards that can also run a Tualatin. Sometimes you can get good prices on those, but they might not give you exactly what you want as far as expansion slots, or being able to fit in a standard ATX case and such.

Some Dell GX150 motherboards support Tualatin, but you have to look at the chipset stepping. They do use standard ATX power, but they don't fit in an ATX case, they don't have ISA, and they need a Dell ribbon connector for the front panel switches. Dell clamshell cases in that time period seem to be pretty interchangeable - so if you happen to have one already, or find one somewhere, then swapping in a GX150 board could be cost effective.
Some Compaq Despro EN boards can also run Tualatin, but those are very compact machines with little expansion.
I doubt there's any prebuilt type boards for Tualatin that have ISA though.

I'm sure every brand must have comparable machines but those are the ones I know about.

I'll add that some laptops also have desktop Tualatin chips - Gericom was notorious for doing this as far as I know, with their Webgine MSW (Uniwill N340S8) and 1st Supersonic M6T (FIC A380) both having 1.2GHz SL5GN Tualatin P3s.

Ah ECS P6S5AT is now not avaible anywhere.
If I must create choice between these two motherboards:
Chaintech 6OJA3T
vs
Epox EP-3VSA
what is better for Win98 (Glide/D3D)?
Edit:
or
Gigabyte GA-6VTXE rev1.0
or
QDI Advance 10T-A

The Chaintech is Intel 815, the Epox is VIA.
For Win98 the i815's 512MB limit doesn't matter, and it will probably won't be as fiddly as the VIA chipsets can be.

The Epox has a DIP BIOS, the Chaintech is PLCC (going by pictures anyway - maybe there's revisions where that changes). If you find one of those more serviceable then maybe that could matter to you.
Epox usually has bad caps, but maybe Chaintech does too, I don't know much about Chaintechs.

Look close at pictures and try to verify that the heatsink retaining hooks on the CPU socket are not broken. That happens a lot.

Interesting... The Asus TRL-DLS is not listed...

None of the PCPartner boards are listed : VIA chipsets and Intel chipsets

No. Both motherboards have chipset VIA Apollo Pro 133T.

https://theretroweb.com/motherboards/s/epox-pronix-ep-3vsa
https://theretroweb.com/motherboards/s/gigaby … -ga-6vtxe-a-1.0

That's why it's hard for me to decide which one to deploy and which one to send out into the world.

For now, I'm probably leaning towards the board I bought as a second one (because it wasn't there before), namely Gigabyte because it also has an ISA slot.

If the chipset is the same, the difference in performance between them cannot be very big, so this decision would make sense. What?
