It surely was fun, and I personally liked the way you detailed and commented the code, but that is not a bootloader, it is a bootload, i.e. something that is loaded at boot, executes some instructions and doesn't actually load anything. In the good ol' days there were tens of similar bootsectors (to be used on non bootable floppies) that could display mesages or draw ASCII art. If anyone wants to play with actual MBR bootloaders, a basic MBR is by Peter Anvin (and Andrea Mazzoleni) in makebootfat: http://www.advancemame.it/doc-makebootfat http://www.advancemame.it/doc-makebootfat and for an example of how much stuff you can actually put inside some 440 bytes, the base reference is mbldr: http://mbldr.sourceforge.net/ http://mbldr.sourceforge.net/
