Legacy USB support enables USB devices to be used even when the operating 
system’s USB drivers are not yet available.  Legacy USB support is used to access the 
BIOS Setup program, and to install an operating system that supports USB.  By 
default, Legacy USB support is set to Enabled. 

Legacy USB support operates as follows: 
1.  When you apply power to the computer, legacy support is disabled. 
2.  POST begins. 
3.  Legacy USB support is enabled by the BIOS allowing you to use a USB keyboard to 

enter and configure the BIOS Setup program and the maintenance menu. 

4.  POST completes. 
5.  The operating system loads.  While the operating system is loading, USB 

keyboards and mice are recognized and may be used to configure the operating 
system.  (Keyboards and mice are not recognized during this period if Legacy USB 
support was set to Disabled in the BIOS Setup program.) 

6.  After the operating system loads the USB drivers, all legacy and non-legacy USB 

devices are recognized by the operating system, and Legacy USB support from the 
BIOS is no longer used. 

7.  Additional USB legacy feature options can be access by using Intel

 Integrator 

Toolkit. 

To install an operating system that supports USB, verify that Legacy USB support in 
the BIOS Setup program is set to Enabled and follow the operating system’s 
installation instructions.
