Firmware Functions
The RSL8 board is setup with BIOS firmware. Some standard PC/AT peripheral devices (e.g. Keyboard/Mouse, Serial Ports, SATA interface) are
directly supported by the BIOS, BIOS extensions and Operating Systems. Some peripheral devices (e.g. Ethernet) are directly supported by
standard communication software (e.g. TCP/IP stacks, TCP packet drivers) others need special programming according to the freely available
sample software (e.g. Watchdog). Please refer to the appropriate documentation for detailed information.

Application Programming Interface (API)
The RSL8 system does not contain any special API beside the installed BIOS. Refer to the BIOS and Operating System documentation for API
specifications.
