Int 21 Fn E909 - Novell Netware - Netware Shell - Convert Dos File Handl [N]
AX = E909h
BX = DOS file handle
Return: AX = 0000h if successful
BX:CX:DX = NetWare file handle
Notes: this function is partially a reverse of "AttachHandle" (AH=B4h)
many NetWare 3.x functions use a four-byte file handle, which appears
to be the high four bytes of the six-byte NetWare handle
