I have one of these en route to me. Can anyone tell me what revision of the board I bought? Is it the right version for the BIOS file posted above? If it is, which file should I burn - 1013AF2_BI0 or 1013AF2_BI1?

Looks like the same board as mine. Are there more variations, besides those with and without the 5.27 V VRM?

I like how Intel went to the level of detail to remove the pins from the RTC socket which aren't needed.

Looks like Batman's Revenge to me, but it is complicated.

I think it is best to look at the current BIOS version and look for either AF1 or AF2 sufix. Then you know. Many of these boards also have OEM specific BIOS versions which reject stock Intel versions (unless you downgrade first or use external programmer).

I think it is more likely this is an aftermarket fix. Most of these late boards had Dallas chips soldered-in and they are all dead now. I personally desoldered at least a half-dozen of these and replaced with socket and sometimes removed unused pins to save time on desoldering/soldering 😀

the 5.27 V VRM

Interesting. Original P66 from 93 release could be first CPU which was powered by 12V rail. No surprise it was quickly dropped on new revisions.

Yes, these boards have only minor differences between revisions and jumpers are identical anyway.

lukas12p, if that is a socket 4 on it, then you have the rarer version of this board, the one with the 5.27 V VRM for running the P66.

That's early revision Socket 4 board. You can easily spot Socket 4 by two unsoldered squares below L2 cache chips.

Recently got one of these boards, but unlike the one posted by lukas12p it doesn't have the voltage regulator, coil and capacitors near the power connector, the component locations are there but unpopulated. It has a jumper near the top memory slot for selecting 60 or 66 though.

Does anyone know if I will be able to run a P66 stable without the VRM? So far I only have the P60 that came with it, but I'd like to try a 66 at some point.

Yeah, P66 works on mine too without the 5.27 V VRM. Kind of makes you wonder which tests Intel was doing which were failing at only 5.0 V on the P66 that needed the extra 0.27 V to pass.

You need an early Pentium 66 for such regulator. Later steppings improved yields and VRM requirement became obsolete. But let's also not forget that 5v rail from PSU could be lower or higher than 5v. So it's entirely possible that your PSU can compensate lack of VRM, especially if it's a modern PSU.

You need to use the Intel bios update utility and it will use ALL 1013AF2*.bi* files to flash the bios in parts. That is how it works.

Hi
I try to make any usage of my "new" motherboard. It works with P60@66, but I can't make COM port work with my mouse (it work with other computers). I tried two motherboard connectors, mouse gets power (I have led installed in it), but it doesn't work in DOS or Win95. COM ports are active in BIOS and recognized in Win95.
Question is:
1. Is there non-standard COM pin-out on this motherboard?
2. Where is PS/2 connector?

If your board doesn't have mini DIN's, the PS/2 connector's solder pads are sitting next to the AT keyboard. Either you can desolder the AT keyboard connector and solder on two mini DIN's (one for the keyboard and one for the ps/2 mouse), or you can solder in some wires to the solder pads and connect it to your own PS/2 header that will be loose. I think I glued or found a way to fudge a ps/2 header onto this board so as not to have the dangling header/wires.

Yeah there is
1 2 3 4 5
6 7 8 9
and
1 3 5 7 9
2 4 6 8

Usually they will list the actual pin numbers next to the onboard connector. Unlucky no serial port connector cable is marked for variant A or B...
