Added more memory. Do I need to chage stuff?

    I've just added an other 2GB of memory to my Fedora RC4 server (32bit setup)

    The BIOS is seeing it nice (I now have 4GB in it).

    Do I need to change things in the OS (fedora rc4) as well, or does it take care of of this?

    You don have to change anything in your OS. Does it show the correct memory size in the "top" command?

    Yes it does show the correct memory size (4137228k) with top :)

    If the RAM is detected correctly by your Linux, you don't need to do anything more.

    With some kernels, you may have problems with detection memory, especially if you have lots of it.

    In these cases you need to either aupply a kernel option to lilo or grub (mem=XZY), or recompile kernel to use more memory - which you don't need.
