If you count the memory in the "usable" regions in the e820 table it adds up to about 4669 Mb. I think you should ask your bios folks how this table says 5Gb since it clearly doesn't.....
This is working as designed. The chipset cannot remap physical RAM out of address space reserved for PCI devices into any other address space. This means that PCI devices like PERC3 cards, which request 128MB of address space, get it, and the system "loses" 128MB of RAM. This is a property of all existing ServerWorks chipsets. Other platforms which use Intel chipsets may not have this limitation.
