+ <title>Installation Problems</title>
+ <p>The hardware watchdog timer which is controlled by the
+ <c>heart</c> port program requires the <c>FORCEvme</c> package,
+ which contains the VME bus driver, to be installed. This driver,
+ however, might clash with the Sun <c>mcp</c> driver and cause
+ the system to completely refuse to boot. To cure this problem,
+ the following lines should be added to <c>/etc/system</c>:
+ </p>
+ <list type="bulleted">
+ <item><c>exclude: drv/mcp</c></item>
+ <item><c>exclude: drv/mcpzsa</c></item>
+ <item><c>exclude: drv/mcpp</c></item>
+ </list>
+ <warning>
+ <p>It is recommended that these lines be added to avoid the
+ clash described, which may make it completely impossible to boot
+ the system.</p>
+ </warning>
