Are you sure that you copied the UEFI files inside the directory /run ? I
did it,but when I reboot,they are deleted. And this is what happens when I
copy them into /run :

root@devuan:~/Dati# cp /usr/share/AAVMF/AAVMF32_VARS.fd /run
root@devuan:~/Dati# cp /usr/share/AAVMF/AAVMF32_CODE.fd /run
cp: error writing '/run/AAVMF32_CODE.fd': No space left on device

/mnt/./monta-fisso
sleep 2

UEFICODE=/run/AAVMF32_CODE.fd
UEFIVARS=/run/AAVMF32_VARS.fd
CD1=/mnt/fisso/OS/ISO/BSD/FreeBSD-13.2-RELEASE-arm-armv7-GENERICSD.img
CD2=/mnt/fisso/OS/ISO/Linux/bookworm_mini_armhf.iso
DISK=/mnt/fisso/bhyve/img/FreeBSD/FreeBSD.img

-device vmware-svga,id=video0,vgamem_mb=16

ERROR : qemu-system-arm: device requires 67108864 bytes, block backend

it seems that /run is not the right place.
