Hi,
I am working on to add two installation options in the isolinux.cfg file. The options are:
1) To automatically install centos (including partitioning the HDD)
2) Manual installation and disk partition

For that I used different ks.cfg files:
1) auto.ks.cfg - For automatic installation
2) ks.cfg - for manual installation

To select the installation option I edited the isolinux.cfg file as follows:

################################################################
default linux
prompt 1
timeout 600
display boot.msg
F1 boot.msg
F2 options.msg
F3 general.msg
F4 param.msg
F5 rescue.msg
F7 snake.msg
label linux
  kernel vmlinuz
  append initrd=initrd.img text ramdisk_size=8192 ks=cdrom:/auto.ks.cfg nousb nopcmcia
label text
  kernel vmlinuz
  append initrd=initrd.img text ramdisk_size=8192 ks=cdrom:/ks.cfg nousb nopcmcia
################################################################

But the problem is when I write "linux text" it starts the 'Automatic' installation. When I done write anything and pressed Enter then also automatic installation starts.
Although when i typed 'text' and pressed Enter then 'Manual' installation started.

My question is: in the default linux distro when 'linux text' is entered then the installation starts in the text mode else in the graphical mode.
I also need to make a similar setup for 'automatic' and 'manual' installation.
Can anyone help me out in this matter.
Help is much appreciated. :-)

Thanks,
Richard
