ATTO FibreBridge 2200R/D, 3200R NVRAM Configuration Parameters
Summary
This section provides information regarding updating the FibreBridge 3200R flash or nvram
parameters using updater.exe (MSDOS-based utility) or 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. Accessing the FibreBridge 3200R via BridgeTools (WinNT and Mac based
utility) precludes the need to reference this summary.
