Hey everyone,

I have a first stage bootloader that works fine. I want to be able to use the a20 line, and some other things before I switch into protected mode. How would I go about turning a one stage bootloader into a two stage bootloader.

Thanks

assuming your using a filesystem, just make your stage2 in a flat binary file and name it something like "stage2.bin" then, rather than loading the kernel, just load that instead..

No, I'm not using a filesystem. The disk image is unformated, but I think I have an idea for loading the second stage

Thanks
