| bootldr | Flash | Boot Loader | primairy loader from chain of trust |
| metldr | Flash | Meta Loader | aka asecure_loader. Loads other loaders |
| appldr | CoreOS | Application Loader | loads vsh.self (Userspace Module) |
| isoldr | CoreOS | Isolation Loader | loading isolated SPU modules |
| lv1ldr | CoreOS | Hypervisor Loader | loads lv1.self (Hypervisor) |
| lv2ldr | CoreOS | Supervisor Loader | loads lv2_kernel.self (Supervisor kernel) |
