what bootcodes for debian-live with grub4dos?

["Charles D. Russell" <worwor@bellsouth.net>]

I want to boot from a FAT32 USB flash drive with a BIOS that does not 
support USB booting, by putting vmlinuz and initrd on my NTSF hard drive 
and invoking grldr to boot with grub4dos. By analogy with the 
configuration for Puppy Linux 
(http://www.murga-linux.com/puppy/viewtopic.php?p=13861#13861), I'm 
guessing that the grub4dos menu.lst should look something like the 
following, but I have two specific questions:

1) what are the correct bootcodes for the "kernel" line when 
debian-live-502-i386-rescue.squashfs is in the root directory of the USB 
flash drive?
2) what is the difference between vmlinuz1 and vmlinuz2 in debian-live 
subdirectory i386/web/ ?
