Also 32bit Linux kernel should be fine with PAE, not?
Yes, it is. But in order to get a 32bit kernel that supports PAE, you need to replace the installed kernel-default package by the kernel-bigsmp one. And even then you might not see the whole 4 GiB, because the BIOS reserves some address space for PCI devices.
OK, i see.
But OP was about 64bit kernel. So why does my openSUSE-10.2-64bit behave like this? I am wondering that i am the only one with a 4GB-Thinkpad(-Z-Series)!
Some (many) 64-bit processors have 32-bit compatibility modes. And most mainboards support multiple processors. Mainboard BIOSes for boards that support such processors have to be able to be configured for all the processors they support. Since there's no one-size-fits-all approach to this issue if both 64 and non-PAE 32-bit chips or operating system can be used, they make it a BIOS configuration option.
So you, as the person who knows what processor, how much RAM and what OS are being used, must take this information and choose a suitable setting for those BIOS options.
Yes, but as i described before, two identical machines, Lenovo Z61p, 4GB RAM, Dial 2 Core T7200 with latest BIOS. Running with Vista 32bit: 4Gig available. Running openSUSE-10.2-64bit: 3Gig available (as with Ubuntu-7-64bit) So maybe BIOS is configured for PAE and has problems with 64bit kernels? Should i test with Vista-64bit? And i can really not find any BIOS setting regarding memory! Frank -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
