The configuration of my machine is: AMD Athlon 64 2800+ 2.8 GHz, MSI mother board supporting 64 bit K8TM/K8MM with a RAM memory of 512 MB ( two 333 MHz 256 MB cards). The problem i am having is in installing Linux. It gives me an error that "You are installing a 32 bit OS on a 64 bit machine".. It installs the OS but none of the packages that come bundled along with it are installed. I have tried all the Linux distributions including Suse 9, Mandrake 10 and Fedora Core 2. Is there any Linux Distribution that supports a 64 bit machine. As after purchasing such a high end machine i cannot install Linux. Please help me out. I shall be grateful to you.
