The quantity of memory in a system is determined at boot time by the VISOPSYS operating system loader. This amount of memory is then passed to the kernel at startup.
In Visopsys, virtual memory is enabled, and uses a paging system to translate linear address to physical address, instead of using a segmented plus paging approach. The size of each page is 4KB, the same as the page table entries in most page table in most operating system. 4KB is chosen because it corresponds to the size of virtual memory page in the earlier X86 architecture.
