I've been trying to code a simple c code program building it into the Keil interface, but the HEX file generated has got the startup.a51 code (from C51 lib) in it and the effective code starts at 0x08??. I didn't make to run the simple piece of code because this seems to lay at the external memory space (I can see the code using the External Memory Editor) and I haven't found a way to "J"ump to this location and run it. I am using the evaluating version of Keil, everytime I try to change the ?PR?main?module location it complains that I am using a limited version I have to set the code at above 4000H.

My doubts are:
- Do I really need this startup.a51 piece of code? If not, how do I get rid of it?
- Where do I set where the code should start if I really have to use the startup.a51 because the startup.a51 has a jump to startup part of the code (at 0x800) but there's a huge gap inbeteween.

Thanks in advance
