I created a default build of OpenSUSE 12.2 using SUSE Studio. I chose the JeOS and Server options. The resulting ISOs do not boot properly on a HP Compaq 8300 Elite CMT (a very recent PC).

Booting the default option gives a blank screen. Booting using the Failsafe option I get the error:
PnPBIOS: dev_node_info: function not supported on this system
PnPBIOS: unable to get node info. Aborting.
I also tried the OpenSUSE 12.2 4.7Gb install DVD. That just boots to a plain green screen.
I tried Ubuntu 12.10, Fedora 17, Clonezilla 2.0.1, Centos 6.3 and they work fine.
