I have a Linux embeded device that consists
CPU, BIOS,FLASH and SDRAM.

Is there any way how to determine the memory address range for BIOS, lash and SDRAM?
(BIOS is 4Mb,Flash 64MB and SDRAM( 4 modules ) has 256MB)
Thanks

The PC memory map has always been roughly the same throughout the years (backward compatability and that).... The 32/64 bit part is the killer... When a PC is in protected mode then the address of memory is weird.. There is an MMU that takes care of all memory management.... Physical and Virtual.... This is probably why no-one has responded.
