<p><span style='font-size:10.0pt;font-family:Verdana'>This is the library for
all storage drivers. It simplifies writing a storage driver by implementing 90 percent
of the code required to support Plug and Play, Power Management, et cetera.
This library is used by <span class=SpellE>disk.sys</span>, <span class=SpellE>cdrom.sys</span>
and the tape class drivers.<o:p></o:p></span></p>
<p><span style='font-size:10.0pt;font-family:Verdana'>No INF file is needed to
