# BIOS/Boot-Time Access

Kiwi provides immediate access to the target device from the moment it's powered on. This allows you to access the target computer during boot time without needing any configuration on the target's end.

If mouse does not work in BIOS, try press `Ctrl-Shift-M`  to toggle mouse in Boot Mode (for Kiwi Pro and Kiwi+ only). The Boot Mode will require the interaction mode to be 'Capture/Release Mode'.&#x20;

Once the Boot-Mode mouse is enabled, there will be:

* &#x20;a message popping up on the right-bottom corner of Kiwi App window<br>
