FLASH Download

1 Diagnostic Description

This utility loads the FLASH memory located on the control processors that are located within the system control architecture, with files stored on the system disk. This allows the nodes to initialize quickly after a reset is performed. This utility can also be used to check the nodes for the correct file versions without forcing a download.
