If it's a hack maybe I should just not worry about the extra .5GB then... I don't really need it, it was just a bit of an annoyance to see the message. When I need more RAM I'll just update to AMD64. -----Original Message----- From: Bill Moran [mailto:wmoran@potentialtech.com] Sent: Tuesday, April 24, 2007 11:55 AM To: Don O'Neil Cc: 'Andy Greenwood'; freebsd-questions@freebsd.org Subject: Re: Memory >3.5GB not used?
