What is a BIOS interrupt call?
BIOS interrupt calls are used to pass messages between the BIOS and the operating system or other BIOS client software. The messages request data from BIOS and return the requested data or action to the caller. BIOS interrupt calls are used to perform some functions such as displaying data to the monitor, reading data from keyboard, etc.
