USB Legacy Support
Common Options : KB/Mouse/FDD, None
Quick Review
This BIOS feature determines if the BIOS should provide legacy support for USB devices like the keyboard, mouse and floppy drive. This is a useful feature when using such USB devices with operating systems that do not natively support USB (e.g. Microsoft DOS or Windows NT).
When enabled, the BIOS will enable legacy support for USB keyboards, mice and floppy drives. You will be able to use these USB devices even with operating systems that do not support USB.
When disabled, the BIOS will not enable legacy support for USB keyboards, mice and floppy drives. You will not be able to use these USB devices with operating systems that do not support USB.
However, the BIOS can only provide relatively rudimentary support. For full functionality, you will need to use an operating system that supports USB and install any necessary driver. Alternatively, you can also enable the USB Port 64/60 Emulation BIOS feature.
