IBM-compatible computers have ROM and I/O device memory not available for program use in the range from 640 KB to 1 MB, and after the MINIX 3 boot monitor relocates itself below the 640-KB limit the memory available for program use is further reduced. In Fig. 4-44, how much memory is available for loading a program in the region between the kernel and the unavailable region if the boot monitor has 52256 bytes allocated to it?ds text data CS 0000800 0005800 19552 3140 2356 0100000 0104c00 19456 0111800 011c400 43216 5912 070e000
