Abstract
A computer system is presented having a mechanism for re-mapping memory address space after system initiation. The mechanism includes a microcontroller embodying an integrated RAM controller and chip select unit. Select logic chooses between output from the chip select unit or output from the RAM controller, depending upon the state of memory chip select registers. The registers are set based upon whether a portion of the memory address space comprises ROM. If the space comprises ROM, then chip select signals are selected. After system initiation, data within ROM can be copied to a RAM, or loaded over a local or distal network, and the select logic chooses RAM controller output to operate the RAM.
