No, but I think it is purely down to the bios to enable the last 1gb or not. If I disable both the h/w and s/w PAE options in the bios then the bios only reports 3gb available and FreeBSD the same and it runs ok (sans the memory leak problem I've also emailed the question list about - with little response). If I enable *only* the h/w PAE option in the bios, both it and FreeBSD report 4gb available, but FreeBSD is visibly slower on startup, the nic doesn't appear to work correctly (DHCP fails) and it is very flaky after login. If I enable *only* the s/w PA option in the bios, both it and FreeBSD report 4gb available, but FreeBSD fails to complete startup, spewing 'entry of nVidia Mediashield metadata is NOT supported' on the console until manually rebooted. > Also, > what happens if the new RAM is the only RAM in the system?

Haven't tried that, but I have the original kernel on the box, so I will. > -There appears to have been a bios problem with using exactly 4 gigs of ram > in the A8N Deluxe boards at one point, not sure if this also showed up on > the Premiums or not.

The bios help(!) says '4gb or more' and it appears to be the only way to get it to enable the last 1gb. After some discussion on the Ubuntu 64 forum I'm going to try the Live CD 64 bit to see if it boots up ok with the 4gb turned on in the bios and if so, it looks like I will have to move to that distro to get this box working properly.
