[expert] Errors on startup

[Michael D. Kirkpatrick]

For some reason, on startup, a couple of my boxes wand to scan for hdb and
hdd devices.  There are none.  After that, it tries to run Hard Drive
Optimization on those 2 non-existing devices and of course it fails.  Other
then the fact that it takes a little longer to start up and displays those 2
error, nothing seems to be affected.  Is there a setting somewhere (Other
then CMOS) to tell linux not to bother checking for anything other then hda.

Thanks in advance.
