Line 1: ~~This is the Category of pages that contains information about how to use some BIOS services.~~ BIOS (Basic Input/Output System) was intended to offer low-level services to system programmers, like changing the video mode, accessing disks, asking system properties (amount of RAM, etc). In [[Real Mode]], these services can be accessed through interrupts (10h for video, 13h for disks, 15h for miscellaneous stuff). You may get the complete list of BIOS interrupts in [http://www.ctyme.com/rbrown.htm Ralf Browns Interrupt List].
