Okay, so I changed BOOTBIOS_MAXSEC and got installboot to work fine. Nothing seems to have changed though, as I still run into the "booting hd0a:/bsd: open hd0a:/bsd: Invalid argument failed(22). will try..." error message at boot>.

"makeactive" in menu.lst for grub did not help either (as I had guessed). -Amarendra [...]
