I read this page and for me

Code: Select all

 *((int*)0xb8000)=0x07690748; works but 

the ASM version

Code: Select all

mov [0xb8000], 0x07690748 

doesn't work -- i used NASM to compile
its says "error operand size not specified" --- any clue why ??

thx for future help

As it says, you haven't told it what size the data you're putting into 0xb8000 is. Try this:

Code: Select all

mov [0xb8000], dword 0x07690748

Although I prefer this:

Code: Select all

mov dword [0xb8000], 0x07690748
