Question: How do we turn off memory detection? I would love to try that.
Try adding the following in to your /Extra/com.apple.Boot.plist (I've never used this myself but I think it's the right boot option)..
<key>UseMemDetect</key>
<string>No</string>
Thanks for the info BlackOSX,
I tried UseMemDetect and discovered it cannot be used at the Chameleon command line (at least it ignored it for me). But it does work when used in the com.apple.Boot.plist, as you instructed. This however did not resolve the issue, so I am willing to bet it is a slot detection issue in Chameleon that has to be addressed in order to solve the issue for all HP DVx laptops.
