So I bought this awesome NIB "ProXellent Transkey" keyboard recently, because it has a great layout and it supports no software macro keys, which is a neat feature that I always wanted to try.
I plugged it into my small AT to PS/2 and PS/2 to USB converters, expecting it to work like every other AT keyboard in my collection. And then absolutely nothing happened. I tried to get it working myself and long story short it works in my BIOS, but doesn't as soon as I boot into Windows (or mac OS, it's a hackintosh).
I've never experienced this behaviour and I have no clue what could cause this. I really like this keyboard so far and I'd really appreciate any help that I can get.
Here's a picture of it, for the curious among you:
