Memory
Main memory resides on an
System memory begins at address 0 and is continuous (flat addressing) up to the maximum amount of DRAM installed (exception: system memory is noncontiguous in the ranges defined as memory holes using configuration registers). The system supports both base (conventional) and extended memory.
∙Base memory is located at addresses 00000h to 9FFFFh (the first 1 MB).
∙Extended memory begins at address 0100000h (1 MB) and extends to 3FFFFFFFFh (16 GB), which is the limit of supported addressable memory. The top of physical memory is a maximum of 16 GB (to 3FFFFFFFFh).
Memory amounts from 256 MB to 16 GB of DIMM are supported, with a
