Added separate dumpers for physical and linear address space, added more information to the TSS dump, fixed breakpoint updates when the address(es) are not yet valid, fixed recursion error when an UNPAGED block is accessed, made string instructions restartable after a fault, and enabled port-trapping in V86-mode.
