I've tried to follow the turorial at http://osdev.neopages.net/tutorials/basickernel.php, but when i finished it didn't work.  I booted up and it read the floppy then it showed a blinking square which usually represents enter text, but i couldn't write anything.  Please help a noob by telling him whats wrong or of a tutorial for writing a kernel in c that works

Well it could be a probblem with the boot loader/pmode init code you're using, you might try changing the boot loader you're using but that's just a guess.

Have you looked at the Mixing C and Assembly guide on this site?
