Create a cdrom for mounting a Madbox 9.10 Usb install

My old machine doesn't boot usb because of the BIOS.

So I made a custom boot-cdrom to boot an install on USB of Madbox 9.10.
More info on this distro: http://crunchbanglinux.org/forums/topic/3384/madbox-liveusb-toram/
Mostly followed this tutorial from Pendrive Linux but also
copied initrd.gz from the already on USB installed cdimage (folder: /capser)
and changed some parameters like custom.seed instead of ubuntu.seed

How to Create a CD to Boot Ubuntu from USB

The following process will enable you to create a Boot CD that can be used to Boot Ubuntu 8.10 from a USB Flash drive on systems that do not natively support booting from USB.

1. Insert the Ubuntu 8.10 Live CD and restart your computer, booting from the CD
2. Open a Terminal and type mkdir -p ubcd/boot/grub
3. Type cp /usr/lib/grub/i386-pc/stage2_eltorito ubcd/boot/grub
4. Type gedit ubcd/boot/grub/menu.lst
5. Add the following information to your menu.lst file and save it to ubcd/boot/grub
   

   title Run Madbox 9.10 from USB DISK
   root (cd)
   kernel /boot/vmlinuz file=/cdrom/preseed/custom.seed boot=casper noprompt cdrom-detect/try-usb=true persistent quiet splash
   initrd /boot/initrd.gz
   boot

6. Type cp /cdrom/casper/vmlinuz ~/ubcd/boot
7. Type sudo gedit /etc/initramfs-tools/modules
   Add the following lines to the modules file and click save:

   usbcore
   usb-storage
   uhci_hcd
   ohci_hcd
   ehci_hcd
   sd_mod
   scsi_mod

8. Type sudo gedit /etc/initramfs-tools/initramfs.conf
   Add the following line to the bottom of the file and click save:

   WAIT=8

copied initrd.gz from the already on USB installed cdimage (folder: /capser) and then

1. Type sudo mkinitramfs -o ubcd/boot/initrd.gz
2. Type mkisofs -R -b boot/grub/stage2_eltorito -no-emul-boot -boot-load-size 4 -boot-info-table -o usbcd.iso ubcd
3. Burn the usbcd.iso to a CD
