extlinux graphical menu with function keys

Hi all,

I have a question regarding the syslinux menu as used on the Ubuntu,
Sabayon, ... live CD's.
According to the syslinux documentation the function keys can be used
to display a help file, but in the menu of these live distros the
function keys are used to pick the resolution, language and keyboard.

I would like to bind a submenu to these function keys. Is this
possible and how can this be accomplished?
Or if anybody knows a place where this topic is documented, please let
me know.

Any help would be greatly appreciated.

They use a nonstandard patch to syslinux which I consider unsupportable
due to just plain awful code.

Which means that "original" syslinux does have function keys
that can be used to display a help file.

My advice is to check if the wanted functionallity is in original syslinux.

If not, I'm definitely open to suggestions for additions... I just don't
want to move gfxboot.

As it happens, I just finished a (hopefully less crufty) patch
to accomplish exactly what you're after. It's not quite as "pretty"
on the screen as SuSE's stuff, but it's much "prettier" code and
HUGELY easier to use. (I wasted several hours trying to make SuSE's
stuff work on my live-CD...)

http://www.valleyhold.org/~gordons/syslinux-optmenus.diff

The message I sent about it should be hitting the list archive soon,
and the patch also updates README.menu with the new keywords.

HTH, let me know if this works for you!

Hi Gordon,

I just looked at your patch to review it for integration. Unfortunately
it seems to have seriously gotten stale.

Furthermore, I'd rather not introduce new core keywords if at all
possible (OPTMENU, OPTMENUS). Any sane syntax to use them with the MENU
leading keyword? If not, can we stick to a single keyword (perhaps
OPTMENU ENABLE F1...?) If it doesn't make sense, then oh well, but...

Other than that, I really like the code, it's pretty clean and fits
nicely in the framework already established, so I'd like to try it out.
Any chance I could get you to refresh this patch against 3.60-pre4 (or
the "adv" branch in the git tree?)

-hpa

Not a surprise, it's been a while on that one - and I'm not actually
positive I wrote it against the most current thing available then. (I
wrote it over a weekend trying hard to get a project out, and was not
always paying as good attention as I should have been...)

Let me ponder that for a little bit; I suspect there's something
reasonable, yes.

I can look at that, sure. First I want to get the current crop of
patches up - they're to different areas of the tree anyway :)
