<para>Hot Plug Events, when implemented, are reported through the
|
|
event-scan RTAS call. These events are surfaced through the fixed
|
|
portions of the RTAS return value. (see
|
|
<xref linkend="dbdoclet.50569337_21249"/>) Some parts of the system may
|
|
be modified without direct support from the OS.</para>
