Hi, I've bought a used Asus P2B 1.02 and there is a missing component missing the PS/2 port. Apparently this (and maybe other things) results in keyboard error/ lots of beeping (attached ps/2 keyboard works on other computers).

Could anyone checkout the component on their own board so I can order/find a new one to soldered in place?

The best photo I found of a board with the component is this:

Best regards,

It's a ferrite bead inductor for emi filtering https://www.google.com/search?q=ferrite+bead+ … 036RO1036&hl=en, you can salvage it from any atx motherboard, it's placed between the 5v fuse and the ps/2 connector power pins and it provides 5v dc trough it for the keyboard/mouse.

Thanks - had a few tries identifying a ferrite bead - and now the ps/2 keyboard port is working 😀

Good job ! looks a screw driver mishap, those beads are brittle and do not take much to break....

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
