Recieved the card today, and trying to figure out this PC/Pci header thing. (JP3)
On the pcb, there is nothing printed. Other than a white line wich are someehat thick in one of the sides.
What pin is one and two? Someone know this? Thanks in advance.

If you got a multimeter and like a good puzzle:
Compare the asus P2B pinout here: PC/PCI or SB-LINK cable. How to make?
with the Yamaha datasheet here: http://www.anime.net/~goemon/hardware/ymf724.pdf
to identify the pins.
Then mark or remove pin 3 to prevent future errors.

Or is the thick white bar of the silkscreened rectangle supposed to mark pin 1?

Well... No multimeter. 🙁
I was just hoping for someone here, having the same issue and resolved it.
After some further investigation, following traces to and from the header, it seems like PIN-1 is at the thick line on the bottom row.
And PIN-2 is above pin-1 in the picture on my card.

I think you can just try it. Worst case scenario it doesn't work, then you invert one of the ends. I think there's no risk of something getting destroyed if you plug it in the wrong orientation (one pin would remain not connected, and 2 signals would be reversed but they both flow in the same direction so no danger of a short)

On second thought. If the thick white line (to the right of the header) indicates Pin's 1 and 2.
Then I am wrong about the top right pin, being PIN-1. I assume that all SB-Link/PcPCI headers are 100% identical.

Just search for a cheap 6pin IDC connector (female/ female), like this:

Assuming you have a compatible chipset and board, connect both ends of the cable and test. If it doesn't work, rotate one end of the cable by 180 degrees and test again - this should be all you need to do.

I can't destroy any component's this way? Safe in the same way as if I connected a floppycable the worng way?

I've tried this a dozen times, on many boards and cards. And yes, I just looked at it like a floppy or IDE cable inserted the wrong way. There's a 50% chance of getting it wrong first time, so all I ever did was rotate one end to fix it. Just ensure the cable is wired flat like that link - it's like a very thin IDE cable. The usual disclaimers apply though, but this is a simple cable.

Thanks mate.... 😀

It worked. Now i need to get it going in MS-Dos-6.22
Going to be a Challenge.
