BIOS At initial boot time, the ROM bank containing the BIOS is banked in. The BIOS initializes the hardware, such as the UART and the video chip, and tries to load the steckOS loader executable (usually LOADER.PRG) from SD card and executes it. If that fails, the BIOS expects a PRG binary uploaded via XMODEM. UART baud rate and the name of the steckOS loader executable can be configured and are stored in the RTC’s NVRAM.
