Thanks, Dag, for the reference to the syslinux list, and to hpa for the 
suggested Ctrl-X workaround.  Unfortunately, the Ctrl-X doesn't work, 
not even when the screen goes dead.

I totally agree with you that the advanced iLO is absurd, but I guess it 
makes HP a few extra bucks: $350 per M$ system should be noticeable.
However, it shouldn't be noticeable to Red Hat.

Anyone have any suggestions on how to deal with this?

Kind regards,
