Thanks for choosing Mandrake Linux PPC.  The following is a short
explanation of the various options for booting the install CD.

All options ending with \"2.2\" will use the 2.2.20-9mdkBOOT kernel.
The default syntax with no suffix uses the 2.4.18-4mdkBOOT kernel.
The default if you just hit enter is \"install-gui\".

install-gui:        	uses XFree86 fbdev mode
install-text:       	text based install
install-gui-old:    	old Xpmac gui
install-net:            allows you to use a minimal boot CD,
                        pulling the rest of the install from
                        a network server
install-net-text:       text mode network install
rescue:                 boots the rescue image
rescue-net:             boots the rescue image from a network server

                  0aWelcome to 09Mandrake Linux0a install help07

In most cases, the best way to get started is to simply press the 0e<Enter>07 key.
If you experience problems with standard install, try one of the following 
install types (type the highlighted text and press 0e<Enter>07):

 o  0fvgalo07 for low resolution graphical installation.
 o  0ftext07 for text installation instead of the graphical one.
 o  0flinux07 for standard graphical installation at normal resolution.
 o  0fexpert07 for expert graphical installation at normal resolution.


To use this CD to repair an already installed system type 0frescue07
followed by 0e<Enter>07.

You can also pass some 0f<specific kernel options>07 to the Linux kernel. 
For example, try 0flinux mem=128M07 if your system has 128Mb of RAM but the default
kernel ($main) does not detect it correctly.
0cNOTE07: You cannot pass options to modules (SCSI, ethernet card) or devices
such as CD-ROM drives in this way. If you need to do so, use expert mode.

The following install types may be used instead of previously notified :
 o  0fvgahi07 for high resolution graphical installation.
 o  0fvga1607 for 640x480 in 16 colors graphical installation.

The following options may be added on the command line :
 o  0freadonly=107 to disable editing disk partitions.
 o  0fdisplay=ackbar:007 to export display to 09ackbar07 machine screen 0 during
    installation.
 o  0fnoauto07 to disable automatic detection (generally used with 0fexpert07).
 o  0fsecurity=n07 to set security level to value 09n07.
 o  0fupdatemodules07 to use the special update floppy containing modules updates.
 o  0fpatch07 to use a patch from the floppy (file named 09patch.pl07).
 o  0fauto_install=floppy07 to enable auto_install using 09auto_inst.cfg07 file on the
    floppy.

You can choose the following kernels :
" . join('', map_index { " o  0falt$::i07 is kernel $_\n" } @kernels) . "
