void K_clear_screen();
unsigned int K_printf(char *message, unsigned int line);
//void update_cursor(int row, int col);
K_main(){
K_clear_screen();
K_printf("Hi\n How is this for a starter OS?",0);
}
void K_clear_screen() {
char *vidmem=(char*) 0xb8000;
unsigned int i=0;
while(i<(80*25*2))
{
vidmem[i]=' ';
i++;
vidmem[i]=WHITE_TXT;
}
}
unsigned int K_printf(char *message, unsigned int line){
char *vidmem=(char *) 0xb8000;
unsigned int i=0;
i=(line*80*2);
while(*message!=0)
{
if(*message=='\n')
{

*message++;
}
else {
vidmem[i]=*message;
