17 * 0x400000 - 0x7fffff CSR
22 * 0x000000 - 0x0003ff diagnostic area, destroyed upon a reboot
23 * 0x000400 - ENDofRAM storage area, available to operating systems
26 * the first word is used by the firmware as a status flag passed
31 * for the start address of the user-available is 0x001000 which is
36 * operating system, a magic ID to distinguish a MS02-NV board from
37 * anything else and a status information providing results of tests
42 * The firmware only handles the MS02-NV board if installed in the
45 * point of view there is no problem using up to 14 such boards in a
46 * system -- only the 1st slot needs to be filled with a DRAM module.
