Ishbar,
The errors are self explanatory although they take a little getting used to.
These are memory test errors, Extended Fast Pattern is a memory test. Here is one of the errors from the log;
Extended Fast Pattern...................
Failed address=265FC044 Read data=555555E7 Expected=55555555
Extended Fast Pattern FAILED 12/01/2008 16:52
This shows the memory address the test failed at, what data was read and what should have been there. Finally on the last line it restates the test, result, date and time.
