The BMC update includes software security enhancements. Refer to the NVIDIA DGX H100 - August 2023 Security Bulletin for details.

DIMM that experienced uncorrectable errors at runtime will be mapped out on the next boot.
Exposed the C1AutoDemotion, C1AutoUnDemotion, and C6Enable setup options.
Moved the CPU setup options page to under the Advanced page in the setup UI.
Added a setup option to restrict host access via IPMI.
Provided the NvramVarsProtectionInOs setup option to prevent the OS from changing the NVRAM at runtime.
Implemented uncorrectable error rate limiting, disabled CSMI (correctable system management interrupts) on error flooding and on the core that reported MLC (middle-level cache) yellow state, and SEL logging when ANF (advisory non-fatal error) threshold was crossed.
Changed the SncEn default setting to disable.

Improved log sanitization to mask the IP address and login credentials by default.
Added support for the --target and --package override from the command-line interface (CLI) using a configuration file.
Enhanced the --target option with the servertype sub-option to resolve unidentified platform errors.

Support for abbreviated firmware update package names.
Enhanced the show_update_progress output to provide a full status report for Redfish.
Support for custom log file path.
The command exits with an error code 1 for any update failure or tool failure.

You can update all the system components on the motherboard tray at one time. Previously, you had to update the components individually.
You can create a JSON file with network addresses and credentials for multiple systems and automatically update multiple systems serially. Refer to Updating Multiple Systems for more information.
