[syslinux] Feature request: delay boot with no prompt display

[Richard Hirst]

What I'd like to do is to display an image via "DISPLAY foo.scr" where
foo.scr contains "^L^Xfoo.img", then wait a second or two, then
autoboot, all without displaying the boot: prompt.

I don't think that is possible ATM, because as soon as you set PROMPT 0
it boots immediately, regardless of TIMEOUT setting.

I can see a couple of ways to do this; one is to change ui.inc so that
TIMEOUT is still taken in to account.  The other might be more
interesting, and that is to add a control to the DISPLAY file format to
specify some delay.  That way, I might put "^D2" in the file to get a 2
second delay after it display the image and before it goes on to
autoboot.  That would let you do other mildly interesting things, such
as have a DISPLAY file that had several screens of info and
automatically displayed them one after another with some delay.

Any chance of either of these, or something similar, being added?

Thanks,
  Richard
