	AH = 47h
	DL = drive number (00h = default, 01h = A:, etc)
	DS:SI -&gt; 64-byte buffer for ASCIZ pathname
Return: CF clear if successful
	    AX = 0100h (undocumented)
	CF set on error
	    AX = error code (0Fh) (see <a href=../../it/80/16.html>#01680</a> at AH=59h/BX=0000h)
Notes:	the returned path does not include a drive or the initial backslash
	many Microsoft products for Windows rely on AX being 0100h on success
	under the FlashTek X-32 DOS extender, the buffer pointer is in DS:ESI
