First of all, please be more specific, show exactly your menu.lst
commands that failed, also show your hardware config, eg, output
of grub "geometry (hdX)" command, X = 0, N etc.

We may be sub-genius, but we are not mind readers on this list!

Here is a stanza from my "menu.lst" that boots FreeBSD,

    # Entry 3:    FreeBSD 4.2 production [sd1s2]
    title   FreeBSD 4.2 production [da1s2a]
    root     (hd2,1,a)
    kernel   /boot/loader
    #root     (hd2,1)
    #chainloader +1

where I have the BIOS drives setup as follows: hd0 == IDE, hd1 ==
SCSI target 1, hd2 == SCSI target 2.

Older versions of FreeBSD "/boot/loader" had problems with this
grub stanza, but they have been mostly fixed (in FreeBSD).
