Yeah - it does not make sense to show the difference between 1.04 and 1.10 - maybe at the time when there should have been only 1.10 left for sales - otherwise it may seem that genuine 1.04 is also fake...

Indeed.
Even more so because I have not succeeded finding good photos of a 1.04 with the extended frequency jumperset. Do they even exist ?

If you look closer at the picture, there is version 1.10 printed on the board - not 1.04 as description says.

First time hearing about p2b fakes.
Looks pretty legit copy-cat work from the pictures.

Some of the chosen examples to show the differences are indeed awkward.
For me the most compelling aspect is the frequency selection jumper set; instead of a 4-pin jumper block plus a separate AGP jumper there are only the 3 jumpers of the earlier board versions.
The board layout chosen by the counterfeiters is practically identical to rev. 1.02.fakeee1.JPG

I vaguely remember when Asus was worried about fake revisions on the P2B, was working for HPc at the time.
IIRC some were taking the rev 1.01 or 1.02 boards and remarking them as rev 1.04 just like you say.
If any one wants to buy an Asus P2B get the P2B-F and skip the plain P2B or P2B-B. Neither was designed for any P3 cpu from start but the P2B-F was.

Hate posting a reply and then have to edit it because it made no sense 😁 First computer was an IBM 3270 workstation with CGA monitor. Stuff: https://archive.org/details/@horun

If the early P2B versions are only used with Katmay cpu and if the BIOS is left intact they are probably all fine, I think ?.
According to the Roland Scheidegger paper the revisions starting with 1.12 are fine for Coppermines too.

Sorry to resurrect this, but I recently acquired a 1.04! And indeed it has 3 BUS Freq jumpers!

Here is posted thread, about difficulty getting a PIII Coppermine to work onto it:

Asus P2B Motherboard: No support for PIII?

From rev 1.0 up to 1.03, they all feature only 3 BUS Freq jumpers:

Rev 1.03
https://www.ultimateretro.net/en/motherboards/9629

Rev 1.02
https://www.ultimateretro.net/en/motherboards/9628

Rev 1.00
https://www.ultimateretro.net/motherboard/image/35409.1.svg

From 1.10 onward there are 4 jumpers:

3 BF jumpers is totally normal because that enables additional frequency dividers (for example 133/33) which are not available with 3 jumpers.

What's so unusual about that?

Many 3Dfx and Pentium III-S stuff.

Below an overview of two common scenarios. There are unfortunately also ASUS boards (like f.e. P2B-D rev 1.06) that have the later clock generator with 16 settings in combination with the early 3-pin jumper block with 8 options.

UPDATE:

I was able to update the BIOS to the latest 1012 (using UniFlash 1.40 in DOS, with the appropriate flash file provided by soggi, thank you soggi! 😀)

As expected (thanks for everyone shedding light on this), my Coppermine 650 did not work. I searched my entire collection, and could not find a suitable PIII (fine a 850EB! 😀, which of course could not work), so at the moment I have to revert back to my PII 400 that came pre-installed with the system)

Say, is jump from my PII-400 to a 600+ PIII that noticeable in mid-late 90's FPS games? I mean I tend to play my games at maximum of 800x600 on GeForce 5200, with NO acceleration (I know, that's crazy)

Thanks!

The jump will be noticeable, the core is 50% faster and profits off the faster cache on the Coppermine chips. But realistically most games from that time perform decently on slower hardware so I wouldn't worry about it too much.
A 400MHz PII is a very authentic CPU for an early P2B too. You can always build a faster system on a newer platform if you feel you need more power.

That's what I was thinking! Thanks!

If possible also the back and the sticker with the serial number?
