I have successfully installed FreeBSD on my computer, but I had a problem with my hard disk, which I solved as documented in this question: http://unix.stackexchange.com/questions/225494/cannot-access-hard-disks-from-freebsd-installation-cd
The solution was to set the variable
during boot. After the installation was completed, I added the line
to /boot/loader.conf and everything worked fine from then on.
Now I have the same problem when starting the GhostBSD from the iso image. I tried adding the line
at the end of the boot options, but the problem still persists.
After reporting the error a few times, the boot continue and I can get to the desktop and start the installer.
However, when the installer tries to format the disk, the error appears again and the installation is aborted.
So, how can I set the parameter
when booting from the installation iso image?
