    Thank you, that is an exclusion of one suspect, the license stamp.

    The build of the NK.BIN file works fine on top of AWARD BIOS, DOS, and a Bootloader developed with Microsoft BSP. Since I replaced the BIOS and DOS with my ROM Bootloader, I also missing BIOS functionallity is a suspect.

    To optimize boot time, I do not use the BSP to write my ROM Bootloader. I rather write/wrote my complete own code. It might be essential to lern more/find detailed documentation of the hand-off requirements/conditions for WinCE (Entry to the NK.BIN image in RAM) on x86 based platforms. Any hint?
