RM386 - SET PAGE TABLE BITS FOR RANGE OF PAGES

AX = 5DE7h
BL = page table bits to be set (bits 2-0 = U/S, R/W, P)
CX = number of pages to set
DX = first page number to set (in first megabyte)

Return:
AH = status 00h successful 8Bh invalid destination page (not in first megabyte) A5h invalid page bits A6h invalid page count (overflows first megabyte)

Note: RM386 traps this function on the initial transition to protected mode caused by the INT instruction, which means it can not be overridden simply by hooking the interrupt
