Abstract
A computer system having at least primary and secondary partitions, a primary write filter for write-protecting the primary partition, and a state machine. The state machine, in response to a need to write persistent data to the primary partition, boots to the secondary partition, disables the primary write filter, boots to the primary partition, writes persistent data to the primary partition, re-enables the primary write filter, and then reboots to the primary partition.
