Setting a Breakpoint at Module Entry

To add a breakpoint to intercept the module initialization event, follow the steps below:
You can only add four breakpoints for module entries due to hardware breakpoint limitations.
  1. Load necessary modules.
    For instructions, see Loading Debug Information or Debugging UEFI BIOS (for loading PEI or DXE modules).
  2. Halt the target and select the desired thread in the Debug view.
  3. Open the Modules view and check if all modules for the selected debug contexts are loaded successfully.
  4. Right-click the desired module and select
