Systems, methods, and apparatuses are disclosed that allow for accessing a bootable partition on a serial peripheral interface device. The device may store a file system image containing an operating system kernel, boot loaders, and other utilities. A firmware stored on the device may include drivers, protocols, and utilities used to make the file system image accessible to high-level firmware protocols operating within a computing system. The file system image may be recognized as a bootable partition and the computing system may be booted from the partition.
