<br>Flags: callout or callback (usually hooked rather than called), Undocumented function<p>
<pre><b>INT 2F - MS Windows WINOLDAP - SWITCHING ???</b>

	AX = 4601h
Return: ???
Note:	the DOS 5+ kernel intercepts this function and copies the MCB
	   following the caller's PSP memory block into the DOS data segment;
	   in conjunction with AX=4602h, this intercept is used by DOS to
	   avoid corruption of the Windows real-mode heap's end sentinel
