@subheading Description

Please refer to @ref{DPMI Specification} for details on DPMI
function call operation.  Also see @ref{DPMI Overview} for general
information.

DPMI function AX = 0x0400

Fills in version information.  The flags are as follows:

@example
---- ---X = 0=16-bit host  1=32-bit host
---- --X- = 0=V86 used for reflected ints, 1=real mode
---- -X-- = 0=no virtual memory, 1=virtual memory supported
@end example

The cpu is 2=80286, 3=80386, 4=80486, etc.

DPMI 0.9 returns major=0 and minor=0x5a.

Zero.  This always works.
