e> (HMA) The first 64 ef="module.php?name=Lexikon&file=search&eid=1&query=kilobytes">kilobytes (minus 16 byte) of the ef="module.php?name=Lexikon&file=search&eid=1&query=extended memory">extended memory on an ef="module.php?name=Lexikon&file=search&eid=1&query=IBM PC">IBM PC. By a strange design glitch the ef="module.php?name=Lexikon&file=search&eid=1&query=Intel 80x86">Intel 80x86 processors can actually address 17*64 kbyte minus 16 byte of memory (from 0000:0000 to ffff:ffff) in real mode. In the ef="module.php?name=Lexikon&file=search&eid=1&query=Intel 8086">Intel 8086 and ef="module.php?name=Lexikon&file=search&eid=1&query=Intel 8088">Intel 8088 processors, unable to handle more than 1 ef="module.php?name=Lexikon&file=search&eid=1&query=megabyte">megabyte of memory, addressing wrapped around, that is, address ffff:0010 was equivalent to 0000:0000. For compatibility reasons, later processors still wrapped around by default, but this feature could be switched off. Special programs called ef="module.php?name=Lexikon&file=search&eid=1&query=A20 handlers">A20 handlers can control the addressing mode dynamically, thereby allowing programs to load themselves into the 1024--1088 kbyte region and run in {real mode}. From version 5.0 parts of {MS-DOS} can be loaded into HMA as well freeing up to 46 kbytes of ef="module.php?name=Lexikon&file=search&eid=1&query=conventional memory">conventional memory.
