USB Configuration
This section is used to configure USB devices.
Legacy USB Support
Due to the limited space of the BIOS ROM, the support for legacy USB keyboard (in DOS
mode) is by default set to Enabled. 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 keyboard is not available and you need to use a USB keyboard to install Windows
(installation is performed in DOS mode) or run any program under DOS, set this field to
Enabled.
Default: [Enabled]
USB 2.0 Controller Mode
Sets the USB 2.0 controller mode to HiSpeed (480 Mbps) or FullSpeed (12 Mbps).
Default:[HiSpeed]
BIOS EHCI Hand-Off
Enable this field when using operating systems without the EHCI hand-off support.
Default:[Enabled]
Hotplug USB FDD support
Allows you to enable or disable the support for a USB floppy disk drive. When set to auto,
the system automatically detects the device and enables the support for the device.
Default: [Auto]
