 ASM Mnemonics
les di, video_buffer
mov al, byte ptr color
mov ah, al
mov cx, 320*200/2
rep stosw
That's code to fill the screen, video buffer is a pointer to 0xa000. It works, but I don't understand what les, rep, and stosw do.

Let's see if I remember correctly...
les = Load ES and DI registers with 32 bit
pointer to video memory (given in video_buffer)
rep stosw = stores the 16-bit word contained in AX register CX times, incrementing the pointer (ES  I) it uses each time it stores a value.
I think that's it....

Ah, thanks a lot.
