hi
i hav ben using redhat /fedora and here i have a rpm package for a kernel which gives the support of bigmem in the kernel

u r using suse,and these rpm packages won't run for u so u need to compile ur own kernel

have a look in the
"newbie guide to kernel compiling by Dr Ozz" in the linux general section in this forum

regards

Don't worry about recompiling or anything. The highmem is needed for greater than 1 gb only. At most, you'd lose the use of ~24mb of ram. Also, don't worry about "execessive" ram use. Only worry if the swap is being used to much.

P.S. with that much ram you'd be able to run knoppix completely from ram. It will run sooo fast.

hi there
i too had the same opinion but the thread i mentioned above has it all
go through all of it.

i cannot test this because i do not have so much memory


and minm may be u can see by using "top" which of ur process is consuming the most regualrly

I thought this is normal, Linux tries its best to make use of the available ram. What's the point of getting more ram if you don't want your system to use it?

ignore it, this is normal on a linux system, it's just being claimed by the kernel for future use. as long as it's not swapping to disk excessively, and there is no system slowdown, there is no problem.

You have to recompile your kernel if you have more than 896 megabytes to get all the megabytes back that you installed. All you need to do is make sure you have the source code version that is the samve kernel version you are using. As su or root you should do "make oldconfig" under the kernel source directory (usually its /usr/src/linux). Then you can type either "make menuconfig" or "make xconfig".

Linux uses some memory for buffering, caching, and other things. Windows users gets confused how memory management in Linux is handled.

All 2.4.x and 2.6.x kernels supports memory up to 64 GB. You just need to set a few options, compile the kernel, and then you will get to use 1 GB of RAM. Pretend that the kernel is an engine. You can add or subtract features that you need or do not need. You can also tweak it to make your system fast or secure it to be used in a server. Almost all OS uses the name kernel, but you will not see or modify it in those OS as much as in Linux.
