Have you tested it? We can't really reply and comment without results, other than the fact that I think your using of assembly for a memset is completely unnecessary. You can do it all in C without any asm needed.

No I haven't tested things, but I can do manual instruction counting based on what code a compiler can produce.
And he's not using a common compiler... (If I had to guess, its Turbo C which doesn't optimize at all)

Code: Select all

. Hope you dont take it too seriously . You are using a 16 bit compiler , turbo C . Regards

Why are you writing a 32 bit OS in a 16 bit compiler? I assume you are using Turbo C by your usage of its ES directive. (Or has Borland released a 32 bit version of Turbo C that I am not aware of?)

OK,
I'm using
1)nontraditional TURBO C++ 3.X PATCH AS FIRST STAGE COMPILING TO PRODUCE 32BIT ASSEMBLY INSTRUCTIONS
2)TURBO ASM 32BIT TO INTEGRATED WITH TURBO C,AND THIS IS THE IMPORTANT PART
so to be clear, C/C++ source file --> TCC --> ASM -->manual modification --> TASM --> OBJ
--> EXE
CheerS,
a.T.d
