# openkal on DOS, through DPMI. TECHNICAL EXPERIMENT ONLY (README): no stability, no support.
#
# A DOS program of this arrangement is a stub (stub/stub.S, an MZ program) followed by an ELF32
# i386 executable: the stub enters 32-bit protected mode through a DPMI host --- CWSDPMI where
# the machine has none --- and loads the executable into one block of memory; this package
# receives it there (src/start.S) and answers openkal's interfaces through DOS (int 21h), which
# DPMI's real-mode simulation (int 31h, 0300h) reaches with buffers in conventional memory.

# The interfaces DOS has a counterpart for. Absent (openkal clause 6.2): contexts, processes as

# backing it (CWSDPMI is DPMI 0.90 and refuses 0504h, measured).
