<p><b>Note:</b>
The DPMS 1.0 server included with the original release of Novell DOS
7.0 supports both the beta and 1.0 specification, setting ES:BX even
if CX and DX are not as specified on entry (since the beta
specification did not use those registers). However, the DPMS 1.1
server included with the March 1994 update does not support the beta
specification
