hello 2 all,
i've installed a very nice gentoo workstation with latest gentoo-sources and KDE 3.1.2 and things like that however, this workstation has 1.5gbyte RAM and i guess the kernel does not take notice about this amount...

i've tried with "append="mem=1536M" to tell the kernel how much memory he can use but unfortunately the total mem is 903120

does anyone has an idea?

best regards

roman

I can't give you exact directions, but theres an option in the kernel that has to do with max mem. There's also an option to determine how much of that mem goes to the kernel and how much to the apps, I'm pretty sure these are one of the firsts config options near the part that you select the prosessor

EDIT: if I knew what I am talking about here, I would ask you to post the output of

cd /usr/src/linux
make menuconfig
Processor Type and Features
High Memory Support

Choose the 4GB option.

If you want to use genkernel try this one:

The easiest way to do it is like ProtectonFault said:
use genkernel --config and then add support for 4 GB and enable HIGHMEM, that should do it
