; Begin_Touch_1st_Meg / End_Touch_1st_Meg
;
; DESCRIPTION:
; These macros should be used by VxDs that need to touch memory in
; the 1st megabyte. For example, if a VxD wanted to examine interrupt
; vector 21h, the code would look like this:
;
; Begin_Touch_1st_Meg
; mov eax, DWORD PTR ds:[21h*4]
; End_Touch_1st_Meg
;
; When building retail VxDs, these macros generate no code. When
; building debug VxDs these macros generate calls to Enable_Touch_1st_Meg
; and Disable_Touch_1st_Meg.
;
; ENTRY:
; None
;
; EXIT:
; None
;
; USES:
; Nothing
