IF your system uses GRUB as boot manager and IF you can provide me a copy= of the GRUB config file, then I could probably try to figure out the sys= tem bootup procedure from it. Just by looking at the GRUB configuration y= ou can see if GRUB directly loads the kernel or if it chainloads specific= block or blocks in a partition. This information would help me to figure= out what component of the bootstrap procedure makes the decision to load= which kernel image file.

I don't use PC-BSD or even ZFS = myself. I only use base FreeBSD 10.2 with UEFI (which does not require in= stallation of any stage0 and/or stage1 bootcode, only a 900k partition wi= th specific type GUID and the file /boot/boot1.efifat written as partitio= n contents with dd) or a standard gpt setup (with /boot/pmbr as stage0 an= d /boot/gptboot as stage1). >=20 > I've heard PC-BSD uses GRUB in some way. Is it possible that GRUB loads= the /boot/kernel directly? If it does, then it does NOT care about the n= extboot hint file at all, unlike /boot/loader. IF (and only IF) GRUB load= s the system kernel image directly from boot partition (emphasis on _dire= ctly_), then you need to somehow configure GRUB to offer a boot menu item= for the specific kernel. Unfortunately I cannot remember how GRUB is con= figured since it been a decade since I last time had to bother configurin= g GRUB.=20 >=20 > You could also ask in PC-BSD forums something like "how do I boot a cus= tom kernel built in /boot/<kernel_name>" ... >=20 > On 23.11.2015 15:36, Isaac Raway wrote: >> Hello, >> >> I've followed the directions on this page to install the experimental >> i915 kernel: >> >> https://wiki.freebsd.org/Graphics/Update%20i915%20GPU%20driver%20to%20= Linux%203.8 >> >> I'm not sure that I booted into it correctly (pretty green with BSD in= >> general, and only some experience with kernel builds on Linux).
