Hi,

Anybody found the pinout for J3 "ATX form connector" bracket? All I need is the PS/2 mouse functionality and no other USB/IrDA.

I have a clone of PCChips M571 v.3.2A and it has similar (if not same) "ATX form card connector" (combined USB, PS/2 and IR headers). You can try this pinout.

Alright, I'll try it. Hopefully the pinout matches.

Thank you! It works!
Now if I would want to I can also add USB functionality onto this board. But pretty much all of the usb disks I own don't play nice with 9x. Even with the NUSB driver......

Nice to see it worked. Socket 7 PCChips mobos usually share their own proprietary standard for these audio, PS/2, USB and IR connectors.

I don't see much use for USB 1.x on this board, but there are some working DOS (USBASPI.SYS + DI1000DD.SYS) and win 9x (I'm not sure if NUSB will work on win95 OSR2.x, but there are other options) drivers for flash drives you can try.
