Hi, I have a generic x86 board, running Linux 2.6.23 which has 768 Mbytes of RAM. My understanding is, I can pass the system memory size through kernel command line: through "memmap": "memmap=640K@0 memmap=255M@1M" The above kernel command line indicates to the kernel there are 255 Mbytes of available memory. My questions is, when I change the "255" to a larger number e.g "768", when I type "free" command Or cat /proc/meminfo, the system still reports 255Mbytes of RAM. Why? How do I fix it?
