There are 3 things you could do: a) Limit your memory size in the loader b) Use partial dumps c) Use network dumps if you have another machine to run the dump server on. Both the netdump partial dump code can be found at: http://www.cs.duke.edu/~anderson/freebsd/ Both may be a

dual booting current/stable on x86?

How do I dual boot -current and -stable from different slices on the same IDE disk? (and linux too.) When I tell lilo to boot hde3, I get the -stable boot2 and /boot/loader from hde2 (ad4s2a). I can then monkey around setting currdev and hints and unloading the -stable kernel then boot
