i think you should confirm your two memory banks really fine firstly. i guess your RAM has two: one 512M and one 256M. And about the kernel parameter, u can refer to the link: http://lxr.linux.no/linux+v2.6.29/Documentation/kernel-parameters.txt 2009/5/28 Bizhan Gholikhamseh (bgholikh) <bgholikh@xxxxxxxxx>: > 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?
