Info: Advises the DPMI host that the specified memory below the 1 MB
boundary may be paged to disk.

You must mark only the conventional memory pages that you own --
such as memory from INT 31H 0100H or allocated via DOS fn 48H.

Use INT 31H 0603H (relock real-mode region) to get these pages
back into memory.
