[syslinux] Graphic file 640X480

[ssaguiar at brturbo.com.br]

I wish to know if there is a way to show a graphic file with 640X480 when starting syslinux bootloader withou showing the boot prompt.
I want to show the graphic, then, after 4 seconds, just boot the linux, with no prompt.

I tryed to make this in the syslinux.conf :

prompt 0
DISPLAY boot.msg
timeout 40

in the boot.msg:

^Xsyslogo.lss

But it doesn't work.
The timeout timer don't work. The syslinux shows the image and then start to load linux imediately.

Thanks for any help.
