Question on adding more CPUs and RAMs
What I need to do when I add more RAMs or more CPUs to my linux server? If I rebuild the kernel, what is the difference between the kernel*i686.config, kernel*i686-enterprise.config & kernel*i686-smp.config. How can I allocate more memory to the kernel? Please help. Thanks a lot

Re: Question on adding more CPUs and RAMs
You also need to increase you swap increase due to increase in your ram size. The swap size is usually 2xRAM.

I guess the system should be able to detect the newly installed RAM & CPU by default when you reboot the system.

Re: Question on adding more CPUs and RAMs
Hello,
you need to compile an SMP kernel to be able to use the multiple CPU's. So probably the *SMP.config should work. I always prefer to set all options myself because then you also get rid of all rubish. By default the configs support all hardware configurations and you probably only need very little of them.
To be able to use very large amounts of memory you have to set the LILO var mem=128M for a 128M system. by default (still true?) it uses only 64M.
