Using More than 4GB of RAM
Hello, I have upgraded my kernel to the latest 2.4.19 SMP kernel available form SuSE. I noted in one of the readme files that the 4GB memory problems had been corrected. I have a dual Processor MSI K8D Master System Board, which still does not operate when each of the 6 memory slots has a 1GB chip installed. This there a problem with my BIOS settings, or is there still a problem with the Kernel? Regards Louie

The MSI K8D seems to have some problems with certain memory setup that I could not reproduce on the system that I have. I suggest some kind of broken BIOS but I don't know yet. Note that we have at SuSE several systems running with more than 4GB, so this is not a generic kernel problem. Just the MSI K8D causes problems with exactly 6 GB, Andreas -- Andreas Jaeger, aj@suse.de, http://www.suse.de/~aj SuSE Linux AG, Deutschherrnstr. 15-19, 90429 Nürnberg, Germany GPG fingerprint = 93A3 365E CE47 B889 DF7F FED1 389A 563C C272 A126

I'm not aware of any "4GB memory problems"

I doubt it is a kernel problem. The kernel doesn't know anything about DIMMs and other low level memory controller configuration details, that is deeply BIOS territory. We have tested successfully with more memory at SuSE, so it's not a generic kernel issue. I would suggest to talk to MSI. One common issue we had with broken BIOS is that they sometimes misconfigure the AGP aperture which is needed for the IOMMU setup for >4GB of memory. You can try to boot with iommu=memaper=2. If that helps it is also a BIOS bug. -Andi
