Default values are hard coded in the drive firmware that is stored in flash EPROM nonvolatile memory on the drive PCB Default values can be changed only by downloading a complete set of new firmware into the flash EPROM An initiator can request and receive from the drive a list of Default values and use those in a Mode Select command to set up new Current and Saved values where the values are changeable Saved values are stored on the disk media using a Mode Select command Only parameter values that are allowed to be changed can be changed by this method See Changeable values defined below Parameters in the Saved values list that are not changeable by the Mode Select command get their values from the Default values storage Current values are volatile values currently being used by the drive to control its operation A Mode Select com mand can be used to change these values only those that are changeable Originally they are installed from Saved or Default values after a power on reset hard reset or Bus Device Reset message Changeable values form a bit mask stored in nonvolatile memory that dictates which of the Current values and Saved values can be changed by a Mode Select command A one allows a change to a corresponding bit a zero allows no change For example in Table 9 refer to Mode page 01 in the row entitled CHG These are hex numbers representing the changeable values for Mode page 01 Note that bytes 04
