@jimp:
Are you seeing the exact same error as the person on that page? That isn't pfSense, so there is no guarantee the behavior would be similar.
Mount the memstick image in another pfSense or FreeBSD box and edit /boot/loader.conf or /boot/loader.conf.local on the stick (create one if it does not exist) and add this line:
kern.cam.boot_delay=”10000″
See if that helps.
I saw it, I did a fresh install at the weekend and I cannot remember what I did to fix it as I thought at the time it was just me. Whatever I did I got past it and all was good.
However, one of my testers was doing fresh install of 2.4b and sent a nice picture..
