Function x86_64::bios_start

pub(crate) fn bios_start(bios_size: u64) -> GuestAddress

The x86 reset vector for i386+ and x86_64 puts the processor into an “unreal mode” where it can access the last 1 MB of the 32-bit address space in 16-bit mode, and starts the instruction pointer at the effective physical address 0xFFFF_FFF0.
