The desktop kernel needs AFAIR PAE support, I'm not sure your CPU has it - that might be the reason for the installation of the default one.
In general: kernel-desktop runs on "newer" hardware only, kernel-default runs also on some older,
Kernel PAE was installed on 11.1 to enable the NX/XD bit on newer machines, basically 64bit processors. The only 32bit procs that support it is the Atom, the Intel Core Solo/Duo & some of the Pentium M procs(Banias and some slower Pentium M's don't have support for it). There was a lot of discussion about how the PAE kernel wasn't very stable on some older hardware(I switched my P3 laptops to default-kernel). Personally, I'm not convinced that PAE should be enabled by default because I'm not sure it's as efficient as not using it. Very few 32bit systems actually have the ability to use more than 4GB RAM. I'm not a programmer, so I dunno. I guess in a way, PAE is kinda like the old Expanded memory system under DOS because it pages out memory from over 4GB into the 4GB range as needed(where ems pages out 64k chunks from over 1MB into the UMB area of an 8086/8088 mode system). I haven't really had time to play with 11.2 much(I finally installed RC2 on my son's machine, an AlthonXP 3200+ but never did figure out why hulu.com locks up the browsers) so I didn't notice the new kernel setup. -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-factory+help@opensuse.org
