The drive maintains four sets of mode parameters: 1. Default values Default values are hard-coded in the drive firmware stored in flash E-PROM (nonvolatile memory) on the drive's PCB. These default values can be changed only by downloading a complete set of new firmware into the flash E-PROM. 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. 2. Saved values 60 Constellation ES.1 SAS Product Manual, Rev. E
