Take boot.iso from the images directory in the RHEL DVD and mount it:
mount -o loop boot.iso /mnt
make a directory and copy all files from /mnt to this dir.
mkdir /root/iso
cd /mnt
cp -pr * /root/iso
cd /
umount /mnt
Look in /root/iso/isolinux
Probably want an isolinux.cfg file like this:
default linux
prompt 0
timeout 0
label linux
kernel vmlinuz
append initrd=initrd.img ksdevice={DEV} linux ip=xx.xx.xx.xx
netmask=xx.xx.xx.xx dns=xx.xx.xx.xx gateway=xx.xx.xx.xx vnc
vncconnect=xx.xx.xx.xx vncpassword=abcdef method=nfs:xx.xx.xx:/{PATH TO
LINUX_DISTRO EXPORTED FROM NFS SERVER} keymap=us lang=en_US.UTF-8
fill in the details. Dont forget to make an NFS server.
To make the iso file use something like:
mkisofs -o "/root/iso/isolinux.iso" -boot-info-table -b isolinux.bin
-no-emul-boot -c boot.cat /root/iso/isolinux
Use this file to boot from an RSA adapter or burn a cd.
Hope this helps

You have to make your own boot cd and insert the information I provided into the
isolinux.cfg.

Hi,
Start by running a vncviewer in listen mode (I use realvnc: vncviewer --listen
from a command line ). Boot the machine to install linux with the cd-rom and you
type:
linux ip=xx.xx.xx.xx netmask=xx.xx.xx.xx dns=xx.xx.xx.xx gateway=xx.xx.xx.xx
vnc vncconnect=xx.xx.xx.xx vncpassword=abcdef method=cdrom keymap=us
lang=en_US.UTF-8
You need to specify IP, method, keymap and lang information otherwise it will
ask you for this before vnc is running.
the ip address is the address you want to give to the machine your installing
linux on. Can also be ip=dhcp
vncconnect is the IP address you ran the vncviewer on
vncpassword is the password. Not sure if it should be encrypted or mot
method=cdrom specify your install media
By booting from a cd-rom you unfortunately have to perform a media check. This
requires output to a screen and a few key presses and I don't know if this can
be disabled. The way I got round this was to use an NFS server, so the boot line
is:
linux ip=xx.xx.xx.xx netmask=xx.xx.xx.xx dns=xx.xx.xx.xx gateway=xx.xx.xx.xx
vnc vncconnect=xx.xx.xx.xx vncpassword=abcdef \
method=nfs:xx.xx.xx:/{PATH TO LINUX_DISTRO EXPORTED FROM NFS SERVER}
keymap=us lang=en_US.UTF-8
eg,
method=nfs:10.2.34.123:/export/RHEL5.4/i386
/export/RHEL5.4/i386 is the path on the NFS server to the DVD distribution on
disk. You have to copy the contents of the DVD to disk.
Heres a useful web page:

Hope this is of some help.
