Debian 3.1 etch only shows 4 out of my 8 gb of ram

mavness · 01-06-2007, 06:53 PM

Any ideas? Im sure its something simple somehwere, but Im not even sure where to begin.

System is a dual 3.06 xeon IBM with 8gb of ram. OS is Debian 3.1 etch with 2.6.15 smp kernel.

Debian only sees 4 gb of it.

Thanks in advance!

You need a kernel that supports that much memory try using COLUMNS=125 dpkg -l | grep linux-image and look for bigmem or highmem or something like this in the kernel name then install/boot into.

Thank you sir, already found some bigmem kernels...

linux-image-2.6.18-3-686-bigmem

but its not an SMP..is it assumed that if you have > 4gb of ram you have more than one processor?

NEVERMIND!!

SMP images merged with non-SMP. After the release of linux-image-2.6.17-2 the SMP and non-smp images where integrated into only one image. After this you will no longer find images like linux-image-2.6.16-2-686-smp and linux-image-2.6.16-2-686 but only one image that will detect at run time the presence of a SMP system and enable or disable the SMP code:

* Sarge: kernel-image-2.6.8-2-686 and kernel-image-2.6.8-2-686-smp
* Etch: linux-image-2.6.17-2-686

So the bigmem one worked!

Thanks for the help HappyTux!!
