In no particular order, my suggestions are: -The A8N-SLI's are extremely picky about the RAM you give them; have you double checked with a memtest run to verify that it's not the problem? Also= , what happens if the new RAM is the only RAM in the system? -Does anything change if you compile for a single processor? FreeBSD should run fine even if it's not taking advantage of the dual cored nature of the processor. -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. You may want to verify that you are running the most recent bios. I found the cause of the invalid option error. From the handbook section o= n the PAE option: "*Note:* The PAE support in FreeBSD is only available for Intel IA-32 processors." Note that it appears that PAE is a system for addressing _more= _ than 4 gigs of RAM (handbook section 8). Since your board only supports up to 4 gigs ( http://www.asus.com/products4.aspx?modelmenu=3D2&model=3D539&l1=3D3&l2=3D15= &l3=3D148), I guess I'm curious why the PAE options exist in the bios.
