Memory trouble
Hi everyone,
This is kind of long, so bear with me...
I have used Linux (FC, SuSE, and recently Debian 3.1) for many years in the past, but have never actually done and modification/configuration of the kernel, and would like some pointers/tips or maybe a useful link to a guide which give good instructions as to how to configure the kernel (specifically for Debian 3.1). I see a few tutorials when I google this topic, but none are specific to Debian (example: they tell you to go to /usr/src/linux, but I don't have that directory =| ).
What I'm trying to do is this:
At work, we've recently installed a new Dell PowerEdge 2800 server with 2 (single-core) 3.6GHz Xeon CPUs w/2MB L2 cache, 8GB of memory, and a few TB of HDD space. We've installed the 2.4.27-2-686-smp kernet and it works fine except for 2 thing:
1) cat /proc/meminfo (and free) shows that it only sees 4GB of memory
2) cat /proc/cpuinfo and dmesg shows only the L1 cache (16K) and L2 cache seems to have disappeared into thin air =(
I believe the solution to problem #1 is to modifiy the kernel settings and set CONFIG_HIGHMEM64G=y (at the moment CONFIG_HIGHMEM4G=y, and the 64G one is commented out), but I can't just edit the /boot/config-2.4.27-2-686-smp file directly, hence I need a tutorial on kernel config.
As for problem #2, I have yet to find any clue whatsoever as to why it's happening and how I can fix the problem, so if anybody can provide any sort of insight to this, I would very much appreciate it.
Thanks in advance,
-Glen
