NOTE
Computer systems that have an unshielded cable attached to a USB port may not meet FCC Class
B requirements, even if no device is attached to the cable. Use s shielded cable that meets the
requirements for full-speed devices.
Legacy USB support operates as follows:
1. When the user applies power to the computer, legacy support is disabled.
2. POST begins.
3. Legacy USB support is enabled by the BIOS allowing the user 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 keyboard and mice
are recognized and may be used to configure the operating system. (Keyboard and mice are
not recognized during this period if Legacy USB support is 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.
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.
NOTE
Legacy USB support is for keyboard, mice, and hubs only. Other USB devices are not supported in
legacy mode.
