Have you tried <ctrl><alt><f4> or f5? IIRC, those should show what goes into dmesg. mark ----------------------------------------------------------------- Mark, I have installed 4 other machines with this same DVD disc. The only thing that is a little different is that we have not attached a hard disc drive to the SuperMicro yet, we were only at the point of testing the memory. Thanks for your advice about <ctrl><alt>F4 I will not be able to try this until I can get to the machine, prob 24 hrs. I'll let you know what happens.
