By default the BIOS enables this feature. What are the advantages of doing so?

Why shouldn't I disable legacy USB on a laptop?

Disabling it made the USB boot to stop working

This link is admittedly very old, but i can not imagine that the function in the BIOS has changed much. Essentially what the Legacy USB Support in the BIOS does is emulate USB Keyboards and Mice as PS/2 compatible devices, enabling operating systems which are not USB aware to accept them as input devices.

So if I use an OS that doesn't need that, I'll be good without it, right? – Jader Dias – 2010-11-04T17:26:38.363
for any modern OS i would imagine so. why do you want to disable it? – Xantec – 2010-11-04T17:28:43.743
