SGABIOS provides a means for legacy PC software to communicate with an attached serial console as if a VGA card is attached. It is designed to be inserted into a BIOS as an option ROM to provide over a serial port the display and input capabilities normally handled by a VGA adapter and a keyboard, and additionally provide hooks for logging displayed characters for later collection after an operating system boots.

Crust improves battery life and thermal performance by implementing a deep sleep state. During deep sleep, the CPU cores, the DRAM controller, and most onboard peripherals are powered down, reducing power consumption by 80% or more compared to an idle device. On boards without a PMIC, Crust is also responsible for orderly power-off and power-on of the device. For this to work, Crust runs outside the main CPU and DRAM, on a dedicated always-on microprocessor called a System Control Processor (SCP). Crust is designed to run on a specific SCP implementation, Allwinner's AR100.

ARM Trusted Firmware provides a reference implementation of secure world software for ARMv7-A and ARMv8-A, including a Secure Monitor executing at Exception Level 3 (EL3). It implements various ARM interface standards, such as:

1. The Power State Coordination Interface (PSCI)

2. Trusted Board Boot Requirements (TBBR, ARM DEN0006C-1)

3. SMC Calling Convention

4. System Control and Management Interface

5. Software Delegated Exception Interface (SDEI)
