Overview of BIOS Features
3.9 USB Legacy Support
USB legacy support enables USB keyboards and mice to be used even when no operating system USB drivers are in place. By default, USB legacy support is disabled. USB legacy support is only intended to be used in accessing the BIOS Setup program and installing an operating system that supports USB. This sequence describes how USB legacy support operates in the default (disabled) mode. 1. When you power up the computer, USB legacy support is disabled. 2. POST begins. 3. USB legacy support is temporarily enabled by the BIOS. This allows you to use a USB keyboard to enter the BIOS Setup program or the maintenance mode. 4. POST completes and disables USB legacy support (unless it was set to Enabled while in the BIOS Setup program). 5. The operating system loads. While the operating system is loading, USB keyboards and mice are not recognized. After the operating system loads the USB drivers, the USB devices are recognized. To install an operating system that supports USB, enable USB Legacy support in the BIOS Setup program and follow the operating system�s installation instructions. Once the operating system is installed and the USB drivers configured, USB legacy support is no longer used. USB Legacy support can be left enabled in the BIOS Setup program if needed. Notes on using USB legacy support: � � � If USB legacy support is enabled, don't mix USB and PS/2 keyboards and mice. For example, do not use a PS/2 keyboard with a USB mouse, or a USB keyboard and a PS/2 mouse. Do not use USB devices with an operating system that does not support USB. USB legacy is not intended to support the use of USB devices in a non-USB aware operating system. USB legacy support is for keyboards and mice only. Hubs and other USB devices are not supported.
