process.
SEGMENT_DEALLOCATE_
Deallocates an extended data segment.

Allocate a selectable segment.
Allocate a flat segment. If not running on a system that supports flat
segments allocate a selectable segment.
<15> = 0
= 1
Return the base-address in the base address parameter.
Allocate a flat segment starting at the address specified in the base-
address parameter. Bit <14> must also be set to 1. If not running on a
system that supports flat segments, allocate a selectable segment starting at
the base address%000000D (%H00080000).
