Hello all, thought I would drop this here for those that know what to do with it. Just got a 512mb memmory module, installed it, and booted. Well, everything seems to be ok....except that linux only sees 510mb total...when it should be 640mb. If someone wants any info from iBook2, just let me know off list...or on I guess, and I will send whatever you want. btw-2.4.7benh kernel from about a week ago or so. john
