    Hey Guys,

    I have a 8088-based system built and I am trying to test my hardware with software. Because the 8088's startup location is 7F0, it has 16 bytes of remaining memory locations available for access.

    I am using NASM for an assembler and it does not allow multiple ORG directives. How would I command the assembler and the 8088 to jump to the 'top' of memory (00000h) once it has reached FFFFF?

    If NASM doesn't allow multiple ORG directives, file a bug report - or download the latest, and see if that's been fixed.

    I believe that I can achieve the desired effects with a near jump in my code.
