BIOS Setup

USB Mouse Function

Due to the limited space of the BIOS ROM, the support for legacy

USB mouse (in DOS mode) is by default set to Disabled. With

more BIOS ROM space available, it will be able to support more

advanced features as well as provide compatibility to a wide variety

of peripheral devices.

If a PS/2 mouse is not available and you need to use a USB mouse

to install Windows (installation is performed in DOS mode) or run

any program under DOS, set this field to Enabled.

USB Storage Function

This field is used to enable or disable the support for legacy USB

mass storage.
