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. 

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. 

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. 

To install an operating system that supports USB, follow the operating system’s 
installation instructions.   

The BIOS can be updated using either of the following utilities, which are available on 
the Intel World Wide Web site: 
•  Intel

®

 Express BIOS Update utility, which enables automated updating while in the 

Windows environment.  Using this utility, the BIOS can be updated from a file on a 
hard disk, a USB drive (a flash drive or a USB hard drive), or a CD-ROM, or from 
the file location on the Web. 

•  Intel

®

 Flash Memory Update Utility, which requires booting from DOS.  Using this 

utility, the BIOS can be updated from a file on a hard disk, a USB drive (a flash 
drive or a USB hard drive), or a CD-ROM. 

Both utilities verify that the updated BIOS matches the target system to prevent 
accidentally installing an incompatible BIOS.
