X-SW-Source: 2005-05/txt/msg00137.txt.bz2 Hi All, I am working on a IXDP425 based plattform, If I understand it correctly there is no bios on it, and so for physical memory on the system, redboot has to depend on constant / #defines at compile time. What if one wants to dynamically detect these ? Why cannot we read the memory registers, while we are in redboot and set up things accordingly ?? ( I remember doing something similar while playing around in netbsd,=20 from smbus via open i/o ports it used to read the memory rows, coloumns etc and find out the size) I am sure there is some glitch in doing this, and I am missing something basic here, can someone please correct me here.
