### Download release
## How to use
#### On Real hardware
### Download release
if your have amd64(x86_64) UEFI computer
Download release and copy the UEFI_fireworks.efi to <USB_DRIVE>/EFI/BOOT/bootx64.efi case independent
#### On real hardware
#### On VM
If you have an amd64 (x86_64) UEFI computer,
download the release and copy UEFI_fireworks.efi to /EFI/BOOT/bootx64.efi (case-insensitive).
run:
you will need OVMF firmware you can get it [here](https://qemu.weilnetz.de/test/ovmf/usr/share/OVMF/OVMF_CODE_4M.fd)
#### On VM
You will need OVMF firmware; you can get it here: https://qemu.weilnetz.de/test/ovmf/usr/share/OVMF/OVMF_CODE_4M.fd
Run:
```bash
qemu-system-x86_64 -machine type=q35,accel=kvm -drive if=pflash,format=raw,readonly=on,file="$OVMF_CODE_PATH" -hda fat:rw:build -boot order=c -smp 4 -s -serial mon:stdio
```
