CALL xxxxh:xxxxh - DOS Protected-Mode InterfaceAn API which provides basic services for protected-mode programs to allocate memory, invoke real-mode software, etc. See also Virtual Control Program Interface. - Vendor-Specific APIs {#idx159538}

CALL xxxxh:xxxxh - Plug-and-Play BIOS(Basic Input/Output System) A set of standardized calls giving low-level access to the hardware. The BIOS is the lowest software layer above the actual hardware and serves to insulate programs (and operating systems) which use it from the details of accessing the hardware directly. v1.0A {#idx160557}

CALL xxxxh:xxxxh - WEB v4.02 - MODULE APIs {#idx160812}

INT 15 - DESQview v2.00+ - "APILEVEL" - DEFINE MINIMUM 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.

INT 1A - PCI BIOS(Basic Input/Output System) A set of standardized calls giving low-level access to the hardware.

PORTIBM PC Portable (uses same BIOS as XT) 0022-0023 - Intel 82358DT 'Mongoose' EISA(Enhanced Industry-Standard Architecture) A 32-bit superset of the IBMInternational Busiuness Machines ATIBM PC AT's expansion bus (which is now known as the ISA or Industry-Standard Architecture bus). CHIPSET - 82359 DRAM(Dynamic Random Access Memory) RAM memory which essentially consists of a tiny capacitor for each bit of memory. Since capacitors do not hold a charge indefinitely, DRAM must be constantly refreshed to avoid losing its contents. Also, the process of reading the contents of the memory are destructive, meaning extra time must be spent restoring the contents of memory addresses which are accessed, so DRAM is slower than SRAM. See also Refresh, SRAM. CONTROLLER {#idx133805}{#idx133810}{#idx133959}{#idx133964}{#idx133967}{#idx133969}{#idx133970}{#idx133972}{#idx133976}
