Thanks Ken, AGP or smth reserves some memory... I am not familiar with Linux at engineering level, sorry... May be for IO on a second CPU, or simmetric on both I received reply also in [suse-sles-e]:
This is normal behavior. x86 architecture reserves an amount of memory for PCI cards and other memory segments. If you put 4GB on such a Board you will see a maximum of 3.5GB depending on which devices are on Board and PCI bus. Oliver Antwerpen

However, SLES 9 finds only 3 Gb instead of 4 Gb. All BIOS settings are default; installation is default.
Thanks!
Does the BIOS see all the memory? Sounds like the AGP Aperture is taking up some system memory. There may be some memory configuration options in the BIOS that you can tweak, but they may make the system unstable.
