-
- ;===== D. MACRO DEFINITIONS ===========================================
- ;
- ; RinitProcStart should take two 32-bit arguments conx and shrx
- ; and place them in eax and ebx.
- ; es and ds should both point to the data segment.
- ; conx must be odd (so we or with 1 just to make sure).
- ; FillProc
- ; DS is already the data segment. ES should also be made the same.
