After he got it I read the large memory howto which states that the max memory size for Linux 2.2.x is 2GB physical/2GB virtual. The memory size seems to limited by the 32bit nature of the x86 architecture. The Xeon seems to have a 36bit memory addressing mode. Can Linux be easily expanded to use the 36bit addressing? Thanks for any info on the subject. - Daniel (Who needs to read more before recommending computers.) -- Daniel Blakeley (N2YEN) Cornell Center for Materials Research daniel@msc.cornell.edu E20 Clark Hall -- To unsubscribe, send a message with 'unsubscribe linux-mm my@address' in the body to majordomo@kvack.org.
