Thanks for ur suggestion. My flash is 4 MB. My processor can address up to 4 GB physical address space. That means after power-on, in shematic should I map the flash memory like 0xFFC00000-0xFFFFFFFF and 0x00000000-0x003FFFFF? 0r in upper address, is it enough to map the 256KB region to the Flash ie 0xFFFC0000-0xFFFFFFFF? and the lower address to 0x00000000-0x003FFFFF

at power-on, on all chipsets for PCs I have used, FLASH is mapped at BOTH 0xffffff0 and 0xffff0.
