Ok, it's on different hardware, but it shows that CentOS 4.4 can address the 4Gb withou problem. And we had SLES9 on the same DL-380 hardware and it shows the 4Gb RAM... Somebody can point me a direction to my lost 150Mb ?? Thanks, Antonio. -- +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Antonio S.
