How to make a RedHat boot cd for network install

http://linuxlab.dk/tipsntricks/netcd

Problem
On a machine with no floppy drive, how do I start a Red Hat network installation? 

Solution:
Make a special CD, using the bootnet.img floppy image as the boot image. 
Copy the RedHat install CDROM (cd no. 1) to your harddisk: 
mkdir myinstallcd
mount /mnt/cdrom
cp -r /mnt/cdrom myinstallcd

Copy the boot image you want, to myinstallcd/dosutils/autoboot/cdboot.img . E.g if
you want the standard bootnet.img: 
cp myinstallcd/images/bootnet.img myinstallcd/dosutils/autoboot/cdboot.img

Or if you have a custom boot floppy image, use that one. 

Delete the file "boot.cat" since a new one will be created when you make
the iso: 
rm myinstallcd/boot.cat

Make the iso image: 
mkisofs  -b dosutils/autoboot/cdboot.img -c boot.cat -r -o myinstallcd.iso
myinstallcd/

Burn the cd with your favorite CD writer program, e.g 
cdrecord -v speed=16 dev=0,0,0 -data myinstallcd.iso

Boot from the cd, you will get the same as if you had booted from the floppy image
you put on the cd.
