Hi, I'm new to OS programming but I do know the C language. I have this code that compiles, links, and turns into a floppy image without a problem. Then I run it with the emulator BOCHS. I type kernel 200+9 into the grub prompt, then boot. The problem is nothing displays on the screen. I think this is a really beginner question, but does anyone know why it's not working?
volatile unsigned char* videoram = (volatile unsigned char *) 0xb8000;
void printstr(char string)
int i = 0;
for (i = 0, i < 2, i++)
videoram[2*i] = string[i];
videoram[1+(2*i)] = 0x07;
void kmain( void* mbd, unsigned int magic )
