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.
