The CONFIG option reads the /pmagic/isolinux.cfg and executes it.
It is almost the same as the following option:
Code:
KERNEL menu.c32
APPEND /pmagic/isolinux.cfg
The only difference is that the CONFIG option does some kind of reset.
UBCD uses menu.c32 to display the menus, while Parted Magic does use vesamenu.c32 to display the menu.
The following code can't display the Parted Magic menu well:
Code:
KERNEL menu.c32
APPEND /pmagic/isolinux.cfg
While the following code works better:
Code:
KERNEL vesamenu.c32
APPEND /pmagic/isolinux.cfg
The CONFIG entry resets ISOLI9NUX/SYSLINUX and reads the specified config file just like it would read the isolinux.cfg or the syslinux.cfg file when it starts the first time.
Code:
CONFIG /pmagic/isolinux.cfg
So the CONFIG option is the cleanest way to display the menu of another bootable CD when it has multiple options.
