1. A basic input/output system (BIOS) system comprises: a set of BIOS memories; a decoding module, when enabled, is operable to: access at least some of the set of BIOS memories to retrieve a decode threshold number of encoded BIOS slices for each set of one or more sets of encoded BIOS slices, wherein a BIOS program is dispersed storage error encoded to produce the one or more sets of encoded BIOS slices; and reconstruct the BIOS program from the decode threshold number of encoded BIOS slices from each set of the one or more sets of encoded BIOS slices; and a BIOS management module operable to: detect a BIOS issue based on one or more of: an operational issue with one or more BIOS memories of the set of BIOS memories, a rebuild issue with one or more encoded BIOS slices of the one or more sets of encoded BIOS slices, and a modification to the BIOS program; determine a BIOS change regarding the BIOS issue; and implement the BIOS change to change one or more of: an encoded BIOS slice, a BIOS memory, and utilization of the BIOS program.
