PS/2 ports why?


Recommended Posts

I have been caualy window shopping for upgrade parts. I have noticed that modern motherboardsHer http://www.newegg.com/Product/Product.aspx?Item=13-157-543

For example still have PS/2 ports.

 

Didn't that interface become very obsolete long ago?

 

Why are those 2 ports still relevant?

For keyboards, N-key rollover so you can hit as many keys as you can reach without any being dropped. Recently some USB keyboards have begun to incorporate it, but for the most part, PS/2 it is. The mice are just subjective (imo) and a USB mouse won't have much in the way of a problem compared to a PS/2 one. Higher polling rate on the USB mouse, too, if it's a gaming one at least.

 

Sometimes the USB keyboard won't be detected in the BIOS, even some USB mice in UEFI. Solution? PS/2 keyboard or mouse.
