Your best chance would be to reserve this memory at boot time, maybe you'll even need to change MAX_ORDER in mm/page_alloc.c to do this... Btw, I hope you are aware that kernel 2.4.2 is old and has a number of (security) bugs. Unless you have very good reasons to use this kernel and you are certain that the machine will never get a network interface you'll probably want to upgrade to something newer. kind regards, Rik -- Bravely reimplemented by the knights who say "NIH". http://www.surriel.com/ http://distro.conectiva.com/ -- Kernelnewbies: Help each other learn about the Linux kernel.
