Roughly here is what can be done. Using the bios, say ppcboot and the boot loader (arch/ppc/boot/xxx) don't map the memory that you want kept aside. That way it won't be used by the kernel vm at all. Should not require any core kernel changes except if you want to write to it there. Even within ppc, this will depend on the processor and how the arch-specific MM mapping is implemented for that processor. Use the ppc-embedded and ppc-dev list for more processor specific help. http://lists.linuxppc.org/index.html#search If you use parameters in the bios to decide size, etc it can keep it flexible. This method is used on other platforms for faster warm boots. Regards Amit Usman S. Ansari wrote: > arch is ppc & i dont have 2nd storage. What other option i have? > > ===== > Usman S.
