Umm.... you can't use BIOS interrupts in protected mode.
and... delete the "TIMES" macro, the dw 0xAA55, and all the "org" stuff(GRUB will do this for you). it might help, you're not writing a stage1 bootloader here(at least it doesn't seem that way).

you have what looks like a stage 1 bootloader, and if it isn't, it's pretty close. So if you went through the trouble to write all the ORG, signature, padding, real-mode print code, why are you trying to use grub as you obviously aren't doing it for the PMode benefits.

Thanks i will clean it up. I understand that you cann't make bios int calls. So what do you do when you print text. It seams you are telling that little bios int screen driver i wrote wont work. So what do i use instead.

I followed this:

I got so close to get something work on GRUB. The problem is compiling and linking. In barebones you comple the "C" code with gcc and Link it with "LD" Which they are linux based which i tried a virtual machine with linux to get those 2 software to work. But that fails. I've tried cygwin but the installer crashes. Have you got any ideas to help me out. I would like a tool on windows will be beter. Barebones only helps on linux.

DJGPP is what I used to use when I developed on a Windows machine.
homepage:
http://www.delorie.com/djgpp/
and for a list of the packages you will need:
http://www.delorie.com/djgpp/doc/ug/int ... djgpp.html
just get those packages, unzip the archives, set your environment variables, and use gcc/binutils

Oh thanks. I will look into that. I hope this one will work. What about a linker because i need to link the multiboot header that is required by grub. I any suggestion 01000101 or anyone?

that package includes GAS (assembler) and LD (linker).

When you say the Cygwin installer crashes, what exactly do you mean? It might be a problem with the copy you downloaded or something. I know it works perfectly for me (on Vista).

Look. I can't do anything. djgpp won't allow me to access the download information form their site. so i am stuffed. I spent on saturday for 3 hours typeing diffrent command options of gcc on linux: "srcdir/gcc/configure" and "srcdir/configure" and i got now where because you have to set cc in envoroment which i have no clue about. face i and i don't ask people to compile and link if for an that will be a anoying. I just have problems not have the right tools for creating an 32 bit mode operating system. I need some help.

I don't really understand the problem that you faced when trying to use GCC on Linux. I'm expecting you want to compile those bare bone source code. I believe you just need a normal GCC in Linux. Maybe you trying to compile that GCC from source. It would help us to help you if you can give us details about your problem.
Can you please tell me which Linux did you use?
