INT 15 - SYSTEM - BUILD ABIOS(Advanced BIOS) The IBMInternational Busiuness Machines XTIBM PC XT/286 and PS/2IBM PS/2, any model models with 80286 or higher processors contain two separate BIOSes. The ABIOS is a protected-mode BIOS which is used by OS/2. For machines without an ABIOS, such as the IBMInternational Busiuness Machines ATIBM PC AT, OS/2 loads the equivalent of the ABIOS from disk. see also CBIOS INITIALIZATION TABLE (PSIBM PS/2, any model) {#idx15742}

INT 21 - LASTBYTE.SYS v1.19 - IOCTL - GET ??? TABLE {undocumentedInformation about a product which is not publicly available from the manufacturer, and must be determined by reverse-engineering (disassembly, trial-and-error, etc.). Undocumented information tends to change -- often dramatically -- between successive revisions of a product, since the manufacturer has no obligation to maintain compatibility in behavior which is not explicitly stated.} {#idx46872}

INT 2F - MS Windows - GET DEVICE API(Application Program[ming] Interface) The defined set of calls which a program may make to interact with or request services of the operating system or environment under which it is running. Because the inputs and outputs of the calls are well-defined, a program using the API can continue using the identical calls even if the internal organization of the program providing the API changes.
