error while installing SLES 8 on 4-way Opteron

Hi, All, I am trying to install SLES 8 on a 4-way Opteron platform. The installation fails at the very beginning, just after it boots, finds some devices and has to show me the installation menu. Instead, the installation displays the error message: "An error occurred during the installation". If I switch between screens, I can find another error messages, such as: "non-volatile memory driver v1.1" and "error -3 while decompressing". On a 2-way Opteron system it installs fine. Are there any suggestions? Has anyone tried to install SLES 8 on 4-way Opteron? Has anyone tried SLES 9 on 4-way Opteron? -- Best wishes, Sergey Tolokunsky
