Memory and Processor question
I've a computer with 2 processors and 2Gb of ram..
I Installed the debian 3.1r2 and it only recognizes one processor and 900 Mb of RAM... Do i need to recompile the kernel or it has and other kernel package or configuration that i can do???? Thx... |
not sure about the ram, that should be fine, but the cpu side, you'd need to enable SMP on the kernel. most distro's contain an smp and non-smp kernels for you, so you shouldn't need to mess with much.

The kernel also needs to have support for large amounts of RAM. Dunno if enabling SMP also gives you the remaining 1100 MB of RAM, but it doesn't hurt to try :) I have the same problem with only 100 MB missing. Good luck!

I am not sure how is in debian, but in Fedora, RH, RHEL, and SuSE, there is a file /boot/config-whatever. This is the configuration file used to build your kernel.
You need to have enabled in this config file: Code:
$ grep -i highmem /boot/config-whatever |
This might help: link

You didn't specify which build of Debian so I am going to assume Debain Stable, Depending on what kernel you want..
If you are runningg the 2.4 kernel it would be apt-get install kernel-image-2.4-686-smp or if you are running the 2.6 kernel apt-get install kernel-image-2.6-686-smp IF the system still does not detect the 2GB of RAM with the 2.6 SMP kernel installed (I believe it will) you may need to recompile the kernel to enable high memory support. In 2.6 the value you need to modify is found in [ Processor type and features -> High memory support ]. Set it 4GB. |
