Hard rebooting a VME's CPU (power-cycle, physical reset button, doodle board & ctrl+y*3) resets the OMS controller's motor positions to zero, which usually results in the restoration of autosaved motor positions.
Soft rebooting a VME's CPU (ctrl+x) does NOT reset the OMS controller's motor positions, which usually results in the restoration for autosaved motor positions for only the motors that have sufficiently non-zero positions (>RDBD), assuming the RSTM field hasn't been changed.

We (APS) have found it invaluable to be able to generate a hard VME Reset through the doodle board. Otherwise, techs would be called in to cycle the power (2 hour delay).Ned
