Here's a good article on the situation: http://kerneltrap.org/node/2450 There was a long thread about this on the Boston Linux Group's mailing list recently. There's a lot about the "PAE" (Physical Address Extension) kernels, as well as some discussion as to whether they were needed or not. Also, many motherboards map the area between 3 & 4gb for other duty, so even if I add another gig of RAM, it isn't clear if I'd actually see it. -- Jonathan Arnold (mailto:[EMAIL PROTECTED]) Linux Brain Dump - Linux Notes, HOWTOs and Tutorials: http://www.linuxbraindump.org Daemon Dancing in the Dark, an Open OS weblog: http://freebsd.amazingdev.com/blog/ -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
