DPMI = DOS Protected Mode Interface

DPMI is the "rules" on how to get to protected mode under Windows or OS/2.
A copy of the 0.9 specification is available via ftp from
qdeck.com:/pub/memory/dpmispec.zip

Other specifications like VCPI are also available in this directory.

If you write standard C code you couldn't care less about any of this.
If you want to write PC specific code, DPMI tells how to do it.
