And finally, after just resetting the bios, it looks right: real memory = 25769803776 (24576 MB) avail memory = 24953413632 (23797 MB) Which in itself is interesting. I reset the same after I had changed the bios battery some time ago and didn't change anything. So whether or not the moving of the memory modules were necessary, I don't know and I probably won't bother checking, at least for a while, but it's a tip I'll look for the next time. Thanks to everybody for your input. -- Eivind Nicolay Evensen
