How to use

In a VM

1. Download dependencies and firmware files (Fedora linux):

sudo dnf install qemu-kvm edk2-ovmf

cp /usr/share/OVMF/OVMF_CODE.fd .
cp /usr/share/OVMF/OVMF_VARS.fd .

2. Prepare dir and copy efifetch.efi:

mkdir -p esp/efi/boot && cp efifetch.efi esp/efi/boot/bootx64.efi

3. Run VM:

qemu-system-x86_64 -enable-kvm \
-drive if=pflash,format=raw,readonly=on,file=OVMF_CODE.fd \
-drive if=pflash,format=raw,readonly=on,file=OVMF_VARS.fd \
-drive format=raw,file=fat:rw:esp

On hardware

Efifetch has never been tested on real hardware. Use it on a real device at your own risk
