[ydl-gen] Booting YDL 6.2

[Keith]

 When I boot up YDL on a system with MAC OS X There is a very short
delay when the initial boot menu for Linux, Mac OS X & CDROM. I would
like to lengthen to the amount of time this menu is displayed to about
one minute. How do I change the time delay?
 I have looked at /boot/etc/yaboot.conf but this file seems to deal with
the second boot menu after the initial one is displayed.


TIA,

Keith
