In the previous problem does it matter whether the boot monitor takes exactly as much memory as it needs or if it is rounded up to units of clicks?

Data from previous problem

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?
