It will pop ROM into 32bit Static RAM (if you have it) using a hardware address decode to intercept any calls to F8xxxx and pass them to the SRAM. I guess that I should have clarified that statement by saying that it will not let you pop ROM into 32bit DRAM. ;-). As for the statement of it doing it automatically, that is a "marketing misconception" (a marketing F*up for non marketeers). It requires you to load the ROM image everytime the machine is rebooted since SRAM goes bye-bye when the RESET line is pulled. > So, you may lose unix and OTHER MMU functions, but you still have > Prom code (I.E. kickstart) running in fast 32 bit memory. > Monty Saine -- William J.
