For complete compatibility with the 8088, newer machines thus contain circuitry which permits the twenty-first address line (A20) to be disabled. The CPU then effectively has only twenty address lines in real mode, just as the 8088 does, and addresses which would extend beyond the one megabyte mark wrap to the beginning of the address space.

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 (2) ABNORMAL EXIT (2) ABORT (146) ABORT PLOT (2) ABORT SERVICING QUEUE JOB (12) ABORT SERVICING QUEUE JOB AND FILE (3) ABORT TRANSACTION (7) ABSOLUTE DISK READ (6) ABSOLUTE DISK WRITE (3) ACC Multiplier (6) ACC Reference Level (3) Access Server Driver (7) ACCESS TYPE (2) AccessDOS (2) ACCOUNTING SERVICES (4) Acer M5105 chipsets (2) Acorn BBC Master 512 (15) ACTIVATE (58) ACTIVATE DLC (3) Ad Lib SOUND.COM (10) AD-DOS (61) Adaptec and OMTI controllers (4) Adaptec controllers (6) adapter 1 (4) adapter 2 (5) adapter 3 (2) adapter 4 (2) ADAPTER CONTROL (7) ADCs GAIN CONTROL (2) ADD AUDIT PROPERTY (5) ADD BINDERY OBJECT TO SET (4) ADD CHARACTER TO KEYBOARD BUFFER OF CURRENT JOB (2) ADD EXTENDED TRUSTEE TO DIRECTORY OR FILE (4) ADD TRUSTEE SET TO FILE OR SUBDIRECTORY (2) ADD TRUSTEE TO DIRECTORY (5) ADD USER DISK SPACE RESTRICTION (4) ADDTO (6) ADJUST SYSTEM TIME (2) Adlib (19) Advanced Power Management (34) Advanced Power Management v1.0 (14) Advanced Power Management v1.1 (7) Advanced Power Management v1.2 (5) ADVANCED SETUP OPTIONS (4) AES INTERFACE (2) AFP 2.0 CREATE DIRECTORY (5) AFP 2.0 CREATE FILE (5) AFP 2.0 SCAN FILE INFORMATION (5) AFP 2.0 SET FILE INFORMATION (3) AFP CREATE DIRECTORY (6) AFP CREATE FILE (4) AFP DELETE FILE (3) AFP GET FILE INFORMATION (5) AFP OPEN FILE FORK (5) AFP RENAME (4) AFP SCAN FILE INFORMATION (5) AFP SET FILE INFORMATION (4) AFVXD (3) AGC TAKE-OVER (3) AI Architects (5) ALIGNMENT CHECK (3) Alladin (2) ALLOCATE (391) ALLOCATE A 4K PAGE (2) ALLOCATE BLOCK OF MEMORY (2) ALLOCATE GDT SELECTOR (3) ALLOCATE LDT DESCRIPTORS (2) ALLOCATE MEMORY (21) ALLOCATE MEMORY BLOCK (2) ALLOCATE MEMORY WITHOUT SELECTOR (2) ALLOCATE NETWORK DESCRIPTOR (2) ALLOCATE PHYSICAL MEMORY (2) ALLOCATE RESOURCE (2) ALLOCATE TEMPORARY DIRECTORY HANDLE (2) ALLOW TASK ACCESS TO FILE (4) ALLOW TASK TO BE SWAPPED OUT (2) Alloy ANSK (5) Alloy MW386 (71) Alloy MW386 v1.x only (2) Alloy MW386 v2 (8) Alloy NTNX (193) alternate address (28) Alternate Entry Point (3) ALTERNATE FUNCTION SELECT (9) ALTERNATE INSTALLATION CHECK (5) ALTERNATE INT 10/AH=A0h (2) ALTERNATE MAP REGISTER SET (6) ALTERNATE MULTIPLEX INTERRUPT (73) ALTMENU (3) AMD Am5k86 (21) AMD Athlon (30) AMD InterWave (3) AMD K6 (30) AMD K6-III (5) AMD PCnet (23) AMD-645 (80) AMD-645 Clock (3) AMD-645 Peripheral Bus Controller (10) AMD-K5 (7) AMIAmerican Megatrends, Inc.(American Megatrends, Inc.)
