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: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
