# Slint UEFI demo This example demonstrates Slint in a UEFI environment.  Here's how it works:  To build this example a suitable UEFI rust target must be installed first: ```shell rustup target install x86_64-unknown-uefi ``` To build, simply pass the `--package` and `--target` arguments to cargo: ```shell cargo build --package uefi-demo --target x86_64-unknown-uefi ``` The produced UEFI binary can then either be tested on real hardware by booting it like any other bootloader or directly with QEMU (the firmware location varies by distro): ```shell qemu-system-x86_64 -serial stdio -bios /usr/share/edk2-ovmf/x64/OVMF.fd -kernel target/x86_64-unknown-uefi/debug/uefi-demo.efi ``` **NOTE:** the OVMF are not support mouse moving. please run it at VM or your PC if you want to use mouse.
