Assuming I have a Bios EPFROM file that is 512K and the first bytes are e.g. 0xff 0xff and all the other remaining bytes are 0x00.
When the system starts it will map the ROM to the top of the 4GB 32bit limit.
Does that mean when I query the memory at address 0xffffffff I should be able to see my 0xff (first byte of my Rom) ?
