Syslinux - Mar 2004 - pxelinux.cfg/default config issues

I've been having some real issues creating a working configuration file for
my PXE Linux 2.03 installation from which I intend to boot diskless
workstations. I've tried a huge number of differences for passing the init
argument but none seem to work.

Current config file should look something like this:

********
default std

label std
    kernel linuz
        append root=/dev/nfs nfsroot=1.1.1.1:/mnt/lfs init=/static/bin/bash
********

It appears to load the nfs share fine but then complains about not being
able to fine bash.
I changed the file to add a prompt so I could enter the line by hand.

entered "std root=/dev/nfs nfsroot=1.1.1.1:/mnt/lfs
init=/static/bin/bash"
which boots to bash  fine.

Why when I try to just run the same commands from a config file is it
different from a manual entry. I guess that I'm just missing something
totally obvious but I just cant seem to work it out. Any help would be
gratefully received.

Many thanks

Manuel

Somewhere in the kernel bootup messages it should say what the command 
line looks like as far as the kernel is concerned.  What does it say?

Yes, using serial redirection. See if your BIOS supports it.  Basically it 
pipes all the on screen stuff to the serial port, and you connect your 
laptop to the serial port and view it (or a serial concentrator, etc).

Sorry for the confusion but the entire config file reas as

********
default std

label std
                 kernel linuz
                 append root=/dev/nfs nfsroot=1.1.1.1:/mnt/lfs 
init=/static/bin/bash
*********

If your talking about the information that screams past as the Kernel is
loading, I haven't got a clue. I can see the last screen (which has no
infomation) but there must be 20 lines that scrolls off screen in less
than 2 seconds. Is there any way of slowing it down?
