Description Michael DeHaan 2007-02-19 23:12:34 UTC 
Description of problem:

The version of syslinux that ships on RHEL4U4 does not support PXE menus.

Version-Release number of selected component (if applicable):

syslinux-2.11-1

How reproducible:

Always

Steps to Reproduce:
1.  use a tftp defaults file that contains menu.c32 code -- assume menu.c32 file
copied from a newer version of syslinux.
2.  watch machine PXE boot
3.  note "unknown option in config file message" and that menu options don't
work (user gets stuck in menu).

  
Actual results:

See steps to reproduce.

Expected results:

Menus work, as with FC6.   It would also be desirable to see the syslinux
package bundle menu.c32 as in fedora.

Comment 2 John Hodrien 2007-03-13 13:13:00 UTC 
Is that example file correct?  I'd always created pxe menus as described in the
syslinux documentation (/usr/share/doc/syslinux-*/README.menu) such that they'd
always have:

DEFAULT menu.c32
PROMPT 0

to actually load the menu code.
Comment 3 Michael DeHaan 2007-03-13 14:29:37 UTC 
It works.  The above example has been tweaked to work around another bug in
syslinux.  Namely that the menu does not timeout regardless of what the timeout
interval is set to.  It will print the timeout but it will not count down. Ergo,
we don't enter into the menu unless the user has requested it.  A bit ugly, but
required.

The example above will launch into the PXE menu when you type "menu" at the prompt.

Your example is also right, though it's not suitable for non-interactive use
from what I've seen, due to the busted timeout handling when using menu.c32.

Anyhow, neither menu item applies here, as menu.c32 does not work on RHEL with
the shipping version of syslinux.  (Nor does it ship menu.c32).  That's what
this bugzilla was about.
