I cd /usr/src/linux then

gmake config

and under "processor type and features" I went to "high memory support" and marked 4G,saved then rebooted.

That seems too easy....did I miss something?

Did you 'make', 'make modules_install' & 'make install'?
It requires a full kernel recompile/install to enable it.

outside of what it takes to install a kernal just edit the kernal configuration for highmem. then install the newly highmem configed kernel. its that simple. I had to do it myself recently.

make sure your kernal modules are installed.

I was using the test26.s kernal from 10.2 and the install never installed the 2.6 modules and few other 2.6 kernal packages. they are on cd 2

so if I cd /usr/src/linux then 'make', 'make modules_install' & 'make install' that will do it?

lol ,Thaks for the link.That is definately needed

You need to compile the kernel. Heres what I do when compiling a 2.6.x kernel.
When you 'make menuconfig' you can choose processor & memory settings.

This is just an example of how I do it.
-------------------------------
Start inside the proper folder w/the kernel you have downloaded.
Be sure & change the /usr/src/linux to point to the new kernel directory.

make menuconfig #(*Setup for your system*)
make
make bzImage
make modules
make modules_install
cp arch/i386/boot/bzImage /boot/vmlinuz-2.6
cp System.map /boot/System.map-2.6
rm /boot/System.map
ln -s /boot/System.map-2.6 /boot/System.map
cd //etc
vi lilo.conf #(*Add new selection, see below*)
cd //sbin
lilo
reboot
(*Login as root*)

If your using a nvidia module you need to reinstall it like.
cd nvidia #(*Whever you located your vid driver*)
sh NVIDIA-Linux-x86-1.0-5661-pkg1.run #(*Varies for your driver*)
#Done



My lilo.conf entry:
image = /boot/vmlinuz-2.6
root = /dev/sda1
label = Slack_2.6.X-SMP
read-only


warning, I'm using scsi raid, so its sda1 for me.
place the proper drive for your system.

That worked great for me, so hopefully it's helpfull.
