How to inject driver into Linux Image ISO?

EXTRACT CD:

1) Boot up a Linux Box (I used WhiteBox Enterprise with 2.4.21-27 kern)
2) Insert CD into CDROM
3) mkdir /cdiso
4) cp -av /mnt/cdrom/* /cdiso

EXTRACT and EDIT INITRD.IMG (The Linux Filesystem)

5) mkdir /cdinitimg
6) find the initrd.gz or initrd.img in /cdiso
7) gunzip -c /cdiso/isolinux/initrd.img > /cdinitimg/initrd.img
- believe it or not the image is compressed
8) cd /cdinitimg
9) mdkir point
10) mount initrd.img point -o loop
11) mkdir /cdimgextract
12) cp -av /cdinitimg/point/* /cdimgextract
13) umount /cdinitimg/point
14) rm -rf /cdinitimg
15) make any changes you need to the initrd.img in /cdimgextract

REMAKE MODIFIED INITRD.IMG

16) mkdir /cdinitrd
17) dd if=/dev/zero of=initrd.img bs=1k count=60960
18) mke2fs -i 1024 -b 1024 -m 5 -F -v initrd.img
19) mount initrd.img cdinitrd -t ext2 -o loop
20) cp -av /cdimgextract/* /cdinitrd
21) umount /cdinitrd
22) gzip --best initrd.img
23) cp initrd.img /cdiso/isolinux/
24) rm -rf /cdinitrd
25) rm -rf /cdimgextract

REMAKE MODIFIED ISO

26) cd /cdiso
27) use this shell script:
-note: you may have to edit it a little to fit your ISO.

#!/bin/bash
# make the new iso and put in root.
mkisofs -o /new.iso -b isolinux/isolinux.bin \
-c isolinux/boot.cat -no-emul-boot -boot-load-size 4 \
-boot-info-table -J -R -V disks .
#

28) now you have a new ISO named new.iso in your / directory

BURN THE NEW ISO IMAGE

29) eject the old cd, and pop in a blank
- make sure you have cdrecord
30) cdrecord -v -pad speed=1 dev=0,0,0 /new.iso

NOTE: For the record, I had to edit a RHEL 6.0 Beta CD to add pvscsci driver
