Hi all, I forward to the lkml a mail I posted on kernelnewbies hoping someone of you can help me. ------------------------------------------------------------------------------------------------------------------------- Hi, for a couple of weeks I worked on some examples about boot process. In my previous post on kernelnewbies I post some of them. Now I have a problem. My goal is to boot from a diskette, load the setup code (4 sectors), load the kernel at 0x10000 and move it at 0x1000 trying to execute a main C routine that should represent the start of the kernel. This C routine print simply "Hello Kernel". For my job I used the examples of Berlin Brown at http://bama.ua.edu/~brown084/main.html because this code is a simplified version of the linux boot process. Attached there is my code, hoping someone of you can give a look at it and tell me if there is something wrong (I think so). Before the jump to 0x0100 all seems work fine. The problem happen when I switch in protected mode and try to jump to 0x0100. Ahhhh!!! I use bochs for my test. PS To build my code type: make clean (when necessary) make all to write on a diskette: make disk
