andsome Posted May 30, 2009 Report Share Posted May 30, 2009 The operating system itself needs to use resources to work. You cannot expect to have the whole of the hard drive available for other uses. :D Quote Link to comment Share on other sites More sharing options...

Boris Posted May 30, 2009 Report Share Posted May 30, 2009 There is usually a BIOS setting called "mapping PCI space above the memory limit" or something like that. You need to to turn this on.Also check that BIOS or other settings in BIOS are not being cached to RAM - that can also cause an issue.
