Do i have right understand that the main differenz at security beetween old BIOS and UEFI are:

The BIOS loads the different firmwares into the RAM and giving the Storage-Addresses to the OS.
After them the BIOS stops.
The UEFI loads the different firmwares into the RAM and using the firmware self to provide a Interface: the Unified Extensible Firmware Interface.
After them the UEFI do not stop.
(If i have a full paranoid, high secure OS where i have read each codeline and have self compiled,
them the UEFI can do nevertheless what they programmer of the UEFI want do to with my PC)

Is this correct ?

how does the Compatibility Support Module (CSM) work ?

BIOS = "old school"... Unified Extensible Firmware Interface ... aka. "UEFI" (Intel/WindozzZ?) = "new school"?

Both can be hacked (ie. firmware bug)... :evil: Coreboot cannot be hacked (yet?). :unknown:
