However, the handbook states that the maximum tested is 1Gig http://www.freebsd.org/FAQ/FAQ50.html; has anyone used FreeBSD 3.x with more than 1Gig of memory, and if so, can we update the handbook? While thinking about this, 2 more questions arose: 1) what is the theoretical maximum virtual memory (4Gig per process x a whole lot of processes), but can the VM system actually handle more than 4Gig of virtual memory (assuming you have the swap)? And finally, is there any interest (or even current work being done) to support the 36-bit addressesing extensions available on most, Intel at least, 686-class processors? That would allow us to support up to 64Gig of physical memory. If not, I'de be glad to work on it (does anyone have >4Gig of memory so I can test it though? :) ) Thanks, Kelly ~kbyanc@posi.net~ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
