Then I installed 2.2.8 also on /dev/wd0s2 (because I encountered a lot of "cannot make makefiles errors" while compiline ports which use imake, like xv and xpaint, installing 2.2.8 solves this problem, anyone?) For default loading the kernel from the 2.2.8 partition I specified in /boot/boot.conf on the 3.0 partition this: set rootdev=disk2s2a: set currdev=disk2s2a: Maybe you have another disk number, but check this maualy by breaking the boot process, the prompt shows the current disk number.
