is ther a website that details the individual registers of the keyboard controller?
/* void update_cursor(int row, int col)
* by Dark Fiber
*/
void update_cursor(int row, int col)
{
USHORT position=(row*80) + col;
// cursor LOW port to vga INDEX register
outb(0x3D4, 0x0F);
outb(0x3D5, (UCHAR)(position&0xFF));
// cursor HIGH port to vga INDEX register
outb(0x3D4, 0x0E);
outb(0x3D5, (UCHAR)((position>>8)&0xFF));
}

The registers you are talking about is NOT in the code. You are talking about the keyboard registers. Not the VGA registers shown in the code.
