I really think it would be easier to make a USB key/disk...
But, I tried the following yearsss ago... so did not test if it is still working...
Copy DVD files to HD (if netinstall, you don't need to copy isos):
cp /mnt/cdrom/syslinux/vmlinuz /boot/vmlinuz-c6
cp /mnt/cdrom/syslinux/initrd.img /boot/initrd-c6.img
mkdir -p /path/to/c6/images
cp /mnt/cdrom/images/install.img /path/to/c6/images/
cp *.iso /path/to/c6/
Add the entry to your grub (change the root to match your setup):
title CentOS 6 Install
root (hd0,0)
kernel vmlinuz-c6
initrd initrd-c6.img
You could maybe also directly specify where the images/isos are:
repo=hd:sd??:/path/to/c6
And be sure that "/path/to/c6" is not formated as you install...
Again, not tested at all...
And I guess you will have 1 try only... if it fails somewhere in
the middle of the install, you won't have a 2nd chance
