[Bochs-developers] RE: Bug in Bochs or my code?

[Chris <cod...@ya...>]

OK, it seems that this also happens on a real cpu :( I checked if the 
memory is overwritten, but this is not so and it would be very 
mysterious, if something overwrites the memory so that it only sets 1 
bit! The next thing is, that the only code which does something with 
memory, before this piece of code, is working!
This problem seems to be a problem which only arises when I reach a 
special code size, because I had those problems already. Another symptom 
is that when the above problem doesn´t arise then the int15h function 
0e820h gives nothing back. And I solved the problem so far that it only 
arises if the code which calls int15h is at a specific position!

Where are the asm and hardware gurus who maybe know what my problem is. 
I could also give the code fpr my loader!

@Stanislav:

I don´t know how to use Instrumentation and at the moment it seems that 
I have not enough time for get knowing Instrumentation!
