+## Install bios update via UEFI
+
+UEFI updates cannot be updated via the iDrac since it only supports BIOS
+firmware files.  If you use systemd boot you can however download the EFI
+firmware file and put it in `/boot/EFI/Dell/bios-update.efi`.
+
+Also write the following efi boot entry file as
+`/boot/loader/entries/z-efi-update.conf`:
+
+```
+title EFI update
+efi /efi/Dell/bios-update.efi
