Configuring MB1 Boot Configuration Table

Use these procedures to customize the Microboot 1 (MB1) Boot Configuration Table (BCT) with static platform-specific settings. The BCT settings that can be customized include:

  • SDRAM timing
  • Pinmux configuration
  • Security
  • Firmware configuration

During a system boot sequence, MB1 bootloader uses the MB1 BCT to configure platform-specific static settings. MB1 executes before other CPUs are enabled. The MB1 stage is owned by NVIDIA and signed by NVIDIA and the OEM.
