Hello,
Thank you for the replies, but I am aware of various methods of getting MAC addresses and am also aware of how to spoof them too. This comes from my anti-cheat background.
This is why I actually may ditch Windows ( after 98SE ) for this project, am actually thinking about DOS if I can't find a version of Linux that suits me.
Luckily I am not OS dependent for this project, I can use what ever I need.
Steve

Isn't your problem less the OS and more the CPU? Even if you were to use MS-DOS, on a modern CPU it would be easy for somebody to hijack the boot process, run a DOS VM that looks indistinguishable from the 'real thing', and then execute your code. How would your program know that the BIOS memory it thinks it is accessing hasn't been spoofed?

I was thinking you were going to be selling a program, but this must be something you want to ONLY run on YOUR computer. Sorry, the NSA or a determined hacker can disassemble your program and figure out your copy protection, and make it run wherever they want - i.e., insert NOPs over your copy protection code.

Hello,
This is not copy protection, this is for a security measure.
The reason I want to use PEEK() as a command is to look at specific memory, the ROM on the mother board.
PEEK() is the direct command I know and it is not reliant on any drivers, API's, DLL's or OS's.
Most modern OS's run in protected memory or just don't allow you to look directly at motherboard ROM's.
I want to write code that reads the ROM memory directly and use some values as part of a password. Some of the password will come from the user, the rest from ROM. Each chip has a serial number, this is one of the things I want to use.
Two reasons for this. Most people use or pick easy passwords, including 40-50 unique characters will stop this, but do it invisibly as far as the user is concerned. Second, will mean that the encryption/decryption will only work on one machine.
I know that any cypher can be broken, it is only a matter of time. I will be using multiple layer of various types.

As I said that can be spoofed so that when you think you are looking at the ROM memory "directly" actually you aren't because your code is running in a VM. Don't you care about that?

Hello,
VM's are not perfect, and I shall be exploiting the flaws in them. Also I will not just be relying on this as a sole check.
This is both an exercise and a problem to be solved for me, I am doing this to push myself.
I have been around computer since '77, whilst everything appears to have got easier on the surface when looking under the hood it is much more difficult.
I have worked in binary, machine code, Cobol, Fortran, Basic ( my preferred language ) and dabbled with a couple of others. My problem today is I am way too rusty, not been actively programming hard stuff for a long time. Most of my recent work ( last 15 years ) has been solving communication/translation issues.
I may never get this to work the way I want, but it will be fun trying.
I am also pleased with the help/attitude here, I was on another forum and was just shot down there. Here I am being given the help and also the reasons behind the help.
Steve
