Hello List, I have a HP DL360 G4 with 2GB ECC RAM and a P4-Xeon with 3 GHz. I installed Debian Sarge netinst on this machine and after examining the system i found out that top only shows 906MB RAM, even /proc/meminfo shows only 906MB. I tried this with both the 2.4 (kernel-image-2.4.27-1-386) and 2.6 (kernel-image-2.6.8-1-386) Kernels. After that I ran memtestx86 to see if I had malicious Memory, but it showed the full 2GB and it ran a whole day without showing any errors. Do I miss anything ? I believe that the standard kernel should work with 2GB... Another machine with 1GB Non-ECC-RAM shows the full 1GB in /proc/meminfo

As you can see, I have access to the full 1GB (well, not exactly 1024MB
but I supose the remaing is eated up by the kernel)
My kernel has # CONFIG_NOHIGHMEM is not set CONFIG_HIGHMEM4G=y # CONFIG_HIGHMEM64G is not set CONFIG_HIGHMEM=y and it IS a stock debian kernel....I would suggest you to check wich kernl is running in that 1GB non-ECC-RAM machine... I (am not sure but) believe the 686 or 686-smp kernels have high-mem enabled.
Good luck Joao Clemente
