Can anyone see any problems with this C++ code?

I linked to the SimNow home page earlier in this thread. Unfortunately that page only contains a link to the Linux version although it says there is a Windows version. If I were you I would consider running Linux for OS development, either as a dual-boot or in a VirtualBox VM. It is far easier to set up and use the GNU tools in such an environment than in Windows IMO.

Looks like SimNow was never updated past Windows XP.

The best alternative is to compile Bochs with debugger enabled.

You can even use the console in qemu to do limited debugging, although it's not as versatile as other tools.

TBH, I think that careful inspection of the generated assembler code should reveal the problem in this particular case, and would be a very instructive exercise; but that becomes exponentially more difficult as the complexity of the source code increases. Some sort of debugging tools is an essential IMO.

The problem is not in the code.
I would say a missing rodata section or something else wrong with the linker.
Or the bootloader

Ok guys.

I have moved to ubuntu for OS dev. I am already finding it much better.

I think the problem here was that I didn't use a loader (assembly code which calls the kernel entry point), resulting in the kernel being executed incorrectly.
