As an addendum to bakunin's post as he has pointed to the history of _memory_management_ of the Intel 8088 and above it might be of interest to have a browse of, note not just swap files but '*.TMP' and '*.OVL' files too:-

(Intel Architecture.)
Bottom 64KB usage, where interrupt vectors reside inside the bottom 1024 bytes.
ROM at the top 64KB of 1MB address space, (shadowed by RAM).
Conventional Memory.
HMA, High Memory Area.
UMB, Upper Memory Blocks.
EMS, Expanded Memory Specification. LIM 4.x - Lotus, Intel, Microsoft Specifiaction 4.x
XMS, Extended Memory Specification.
DOS Extenders.
The '.OVL' file extension.
The use of '.TMP' files.

These are all related...

And as a subdivision:-
VCPI, Virtual Control Program Interface.
DPMI, Dos Protected Mode Interface - Superceded VCPI.
Unreal Mode of running.

There is much more and all this is of historic interest but shows how we have gotten to where we are now, especially in the Intel architecture arena...

NAME

     iir -- Intel Integrated RAID controller and ICP Vortex driver

SYNOPSIS

     To compile this driver into the kernel, place the following lines in your kernel configuration file:

           device pci
           device scbus
           device iir

     Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

           iir_load="YES"

DESCRIPTION

     The iir driver claims to interface with the Intel integrated RAID controller cards, and all versions of the ICP Vortex controllers (including
     FC).

HARDWARE

     Controllers supported by the iir driver include:

     o   Intel RAID Controller SRCMR
     o   Intel Server RAID Controller U3-l (SRCU31a)
     o   Intel Server RAID Controller U3-1L (SRCU31La)
     o   Intel Server RAID Controller U3-2 (SRCU32)
     o   All past and future releases of Intel and ICP RAID Controllers.

     o   Intel RAID Controller SRCU21 (discontinued)
     o   Intel RAID Controller SRCU31 (older revision, not compatible)
     o   Intel RAID Controller SRCU31L (older revision, not compatible)

     The SRCU31 and SRCU31L can be updated via a firmware update available from Intel.
