BIOS settings

A USB keyboard is not fully available before Windows starts up. There are not restrictions to

using a USB keyboard when editing the BIOS. To be able to select a boot menu before

Windows starts, however, connect a PS/2 keyboard.

Caution
Activate the "USB legacy Keyboard/Mouse" feature only when a USB keyboard or mouse is

connected. A requirement for activation is that "USB BOOT" <enable> has been selected in

the BIOS.

Note
To edit the BIOS on the operator device with a touchscreen, connect a USB keyboard or an

external PS/2 keyboard.
