+QEMU 5.1 has three options:
+ 1. ``-bios default`` - This is the current default behavior if no -bios option
+ is included. This option will load the default OpenSBI firmware automatically.
+ The firmware is included with the QEMU release and no user interaction is
+ required. All a user needs to do is specify the kernel they want to boot
+ with the -kernel option
+ 2. ``-bios none`` - QEMU will not automatically load any firmware. It is up
