assembly on windows 7

Question

how can i make a device input and output control program on windows 7??

Previously there was an option called debug where we wrote our programs. but as far as i know this feature is no more in windows 7. how can i do assembly on windows7??

Answer 1

Debug is available on Windows 7 32 bit, but not 64 bit.

Answer 2

You can use an assembler such as NASM, YASM, etc., or MASM which is free with Visual Studio Express (for non-commercial use).

I was thinking of Grdb, but it is only available for 32-bit, as a debug alternative.

I'm not sure what you are asking for with your first question, so I cannot answer it. I hope the above answers your second question.

Answer 3

It sounds more like you want to write a device driver? If so, download the Windows Driver Kit from Microsoft.

You can use this to write your driver in assmbly code if you wish. Be aware that this is NOT a trivial task.

What may be a better idea for you is to either install the WinXP virtual machine feature that comes with Windows7, or install WinXP/98/95 on an old machine, and do your coding on that. Under those OSes the driver model was simpler, and you could easily access the interrupts directly and/or easily elevate yourself into Ring 0 if you needed to.
