What I understood from his reply was that he isn't allowed to use direct methods like putc() and putchar(). @Sonu, if you want to work at the kernel level, you will have to write device specific terminal output code. If I remember correctly, you need to call interrupt 10h. See http://en.wikipedia.org/wiki/INT_10 for example. SB -- l...@iitd - http://tinyurl.com/ycueutm
