Usage guidelines
Before a Boot ROM image upgrade starts, the Boot ROM image validity check function examines the
upgrade Boot ROM image for file validity or incompatibility with hardware. If the Boot ROM image
passes the check, the upgrade process starts. If not, the system does not perform the upgrade.
Examples
# Enable Boot ROM image validity check.
<Sysname> system-view
[Sysname] bootrom-update security-check enable
