Hello misc@
Target machine is a work laptop so unfortunately I can't change the main
bios settings or touch the main hard drive (sd0). I'm using the bios
'one time boot' menu to boot from an external 250Gb usb hard drive as
sd1.
First and second stage boot both load successfully (see below) but the
second stage hangs when trying to load the kernel.
Everything works if I boot /bsd from cd0a via 'boot -a' to put root and
swap on sd1, but clearly this isn't ideal.
I've tried a couple of different USB hard drives with the same result.
Thanks in advance for any ideas or suggestions.
Martin
