ATTO FibreBridge 2100R NVRAM Configuration Parameters Summary

This section provides information on updating the ATTO FibreBridge 2100R flash or nvram

parameters using updater.exe (MSDOS-based utility), SCSI Read Buffer or Write Buffer

commands. The buffer ID identifies the respective field for either updater input or via the

Read/Write Buffer commands. The nvram offset is provided to facilitate interpretation of nvram

contents directly.
