Help! I just used freebsd-update to upgrade a system to FreeBSD 9.1-RELEASE-p5 to close the latest security holes. I then rebuilt my custom kernel and tried to reboot. I'm now getting the message Can't work out which disk we are booting from. Guessed BIOS device 0xffffffff not found by probes, defaulting to disk0: at boot time. The strange thing is that when I boot the system from a FreeBSD 9.1 (AMD64) USB key, I can mount and read the file system on the hard drive that will not boot. There doesn't seem to be any problem with it. I've tried copying /boot/loader over from the USB key; still can't boot. Tried moving the GENERIC kernel over from the USB key into /boot/kernel, just in case there was a problem with my custom one; still can't boot. Not sure what to try next. Any ideas would be much appreciated! --Brett Glass
