Re: USB Legacy in BIOS

Attila the Hun 1,
For XP computers, disable USB legacy support in your bios.

What is legacy support?
In USB terms, this is USB device support built into, or specific to, a
particular computer system. Legacy mode support is inherent to a system and
is typically provided by legacy hardware interface emulation.
Legacy mode support allows devices to function in an operating environment
that is not USB-aware. For example, legacy mode support for a USB keyboard
and mouse resides in the system BIOS and presents the keyboard and mouse
data via the port 60h/64h/IRQ1/IRQ12 interface.

I'm having some problems with my PC. I went into BIOS and one of the
options
is to enable, disable USB Legacy. What is the purpose of USB Legacy? Also
what will the result be if I leave it disabled?
Any help would be greatly appreciated!
Thanks, attilathehun1
