This should be 'chkconfig ipmi on'.

You have installed the i586 version of the 2.6.22-9.61.fc6 kernel,
which unfortunately does not have the ipmi drivers built and
included.  You need to install the 2.6.22-9.61.fc6.x86_64 version of
the kernel.  This was a fairly common problem in F6 - the i586 kernel
got installed instead of the i686 kernel, and i586 has a lot of
modules missing.

You can use the Dell Update Package (DUP) for the BMC, if one exists
for a PE840. It's new enough there may not be such.  If so, it will be
on  This doesn't require OMSA, but it does require
you to be running a kernel with the drivers.
