Well, I was going by the System Monitor that is included with GNOME. The cat /proc/meminfo results in a MemTotal of 224436 kb. When I try the mem=288M it gives me an Error 28: Selected item cannot fit into memory. I find that puzzling since the BIOS reports the full 288M. Running dmidecode shows that the maximum memory for the system is actually 384M, but I don't have another chip to put in and I don't think that would be worthwhile anyway unless I can get this figured out. I actually know about the thinkwiki site. It helped me solve my audio problems, but there is very little info on there about memory issues. I'm beginning to wonder if I need to update the BIOS or maybe dmidecode is wrong about this system. It hasn't been wrong on other systems I used it with, but this could be a quirk of the IBM system.
