Respected Sir, I am understanding the code of POST for RAM. In the comment of Memory.c file for Address line test.....It s written that

*"In the actual code, we start with address sizeof(ulong) since our test pattern we use is a ulong and thus, if we tried to test lower order address bits, it wouldn't work because our pattern would overwrite itself."*

Here if we try to test lower order address bits then why pattern gets overwritten. I cant understand this. Please Explain me with example. What happens if we start with value 1 ?

Thanks, Amit Bhorania
