I have tried that, but it doesn't work. It works fine when used on a
CD-ROM, but not when used on an hard-drive. The grub menu is shown
correctly, but when selecting the install entry, it freezes on
"Loading ...". When trying to boot using commands, it also freezes after
entering "kfreebsd /boot/kernel/kfreebsd.gz".
