Boot Live CDROM with Grub

Hello, I can make a bootable CD using GRUB + El Torito no-emulation mode.  It's
almost completely explained in the GRUB manual, section 3.4.

I want to do more,  I want to offer the user who boots from the CD Live or from
a hard disk partition, it's a CD Live with XORP.

 So I built the following menu.lst file: 

title FreeBSD 6.1
        root (hd0,0,a)
        kernel /boot/loader

title CD Live XORP 1.3
        root (hd1)
        kernel /boot/loader

>From GRUB manual, the device syntax is like this:


   `[]' means the parameter is optional. DEVICE should be either `fd'
or `hd' followed by a digit, like `fd0'.  Can I set CDROM device?

I have added last line in

$ cat /boot/grub/
(fd0)   /dev/fd0
(hd0)   /dev/ad0
(hd1)   /dev/acd0

Using this file I can boot " FreeBSD 6.1", but not " CD Live XORP 1.3".  

However when I try set CDROM on grub:

grub> root (hd1)

Error 21: Selected disk does not exist

So the question is: how can I create a GRUB configuration to boot CD Live XORP

Thanks in advance,
