In this third part of the "Let's Code MS DOS" series we explore the VGA graphics card. I will show you how to enable graphics mode, because the PC and DOS boot up in a text mode, which is backwards compatible to earlier PCs. We touch the subject of software interrupts, the API of the BIOS and DOS, as well as I/O ports to program the VGA card's palette registers.
