Understood. I ditched all the AV live CDs other than AVG and KAV. As well as made my very first successful XP based rescue DVD.

For Ubuntu I found a tutorial on the internet to put x86 and x64 version of Ubuntu in the same ISO. Here it is:
QUOTE
You can create a DVD that contains both versions of the live CD:

   1. Download ubuntu-10.10-desktop-i386.iso and ubuntu-10.10-desktop-amd64.iso.

   2. Create a folder structure for the DVD:
CODE
$ mkdir -p ubuntu-10.10-desktop-i386-amd64/boot/{grub,iso}
$ mv ubuntu-10.10-desktop-{i386,amd64}.iso ubuntu-10.10-desktop-i386-amd64/boot/iso/


3. Save the following as ubuntu-10.10-desktop-i386-amd64/boot/grub/grub.cfg:
CODE
# Derived from /boot/grub/loopback.cfg from ubuntu-10.10-desktop-i386.iso and ubuntu-10.10-desktop-amd64.iso.
menuentry "Try Ubuntu without installing (32-bit)" {
   loopback iso /boot/iso/ubuntu-10.10-desktop-i386.iso
   linux   (iso)/casper/vmlinuz  file=/cdrom/preseed/ubuntu.seed boot=casper iso-scan/filename=/boot/iso/ubuntu-10.10-desktop-i386.iso quiet splash --
   initrd  (iso)/casper/initrd.lz
}
menuentry "Try Ubuntu without installing (64-bit)" {
   set gfxpayload=keep
   loopback iso /boot/iso/ubuntu-10.10-desktop-amd64.iso
   linux   (iso)/casper/vmlinuz  file=/cdrom/preseed/ubuntu.seed boot=casper iso-scan/filename=/boot/iso/ubuntu-10.10-desktop-amd64.iso quiet splash --
   initrd  (iso)/casper/initrd.lz
}
menuentry "Install Ubuntu (32-bit)" {
   loopback iso /boot/iso/ubuntu-10.10-desktop-i386.iso
   linux   (iso)/casper/vmlinuz  file=/cdrom/preseed/ubuntu.seed boot=casper only-ubiquity iso-scan/filename=/boot/iso/ubuntu-10.10-desktop-i386.iso quiet splash --
   initrd  (iso)/casper/initrd.lz
}
menuentry "Install Ubuntu (64-bit)" {
   loopback iso /boot/iso/ubuntu-10.10-desktop-amd64.iso
   linux   (iso)/casper/vmlinuz  file=/cdrom/preseed/ubuntu.seed boot=casper only-ubiquity iso-scan/filename=/boot/iso/ubuntu-10.10-desktop-amd64.iso quiet splash --
   initrd  (iso)/casper/initrd.lz
}
menuentry "Check disc for defects (32-bit)" {
   loopback iso /boot/iso/ubuntu-10.10-desktop-i386.iso
   linux   (iso)/casper/vmlinuz  boot=casper integrity-check iso-scan/filename=/boot/iso/ubuntu-10.10-desktop-i386.iso quiet splash --
   initrd  (iso)/casper/initrd.lz
}
menuentry "Check disc for defects (64-bit)" {
   loopback iso /boot/iso/ubuntu-10.10-desktop-amd64.iso
   linux   (iso)/casper/vmlinuz  boot=casper integrity-check iso-scan/filename=/boot/iso/ubuntu-10.10-desktop-amd64.iso quiet splash --
   initrd  (iso)/casper/initrd.lz
}
menuentry "Test memory" {
   loopback iso /boot/iso/ubuntu-10.10-desktop-i386.iso
   linux16 (iso)/install/mt86plus
}

4. Generate an ISO image:
CODE
$ grub-mkrescue --output ubuntu-10.10-desktop-i386-amd64.iso ubuntu-10.10-desktop-i386-amd64


You can now burn ubuntu-10.10-desktop-i386-amd64.iso (1.4 GB) to a DVD and choose either 32-bit or 64-bit options at boot.

This works for both installation and live use. I have tested it by making an ISO myself. But I am not being able to integrate it into easyboot.
If I am not mistaken this tutorial uses grub to load the x86 and x64 ISOs.
I've tried to make it work both using ubuntu.zip and ubuntu.bif. Both failed.
I think the method that would work for this is extract the ISO to /disk1/ and call ELTORITO.IMG. ELTORITO.IMG is the only file I am seeing in this ISO that looks like a loader, located in /BOOT/GRUB/I386_PC inside the ISO.
Here is the complete folder tree in the ISO:
CODE
ubuntu-10.10-desktop-i386-amd64\

      DIR [BOOT]\
      DIR boot\

     2048 Bootable_NoEmulation.img

***edit***
Looking back at the tutorial, it looks like "$ grub-mkrescue" automatically puts a boot loader in the ISO that it makes.
Also there are so many .lst files, no idea which one to choose for kicker image. None of them look like a menu.
I am way over my head, and completely lost.

I cannot find out the right menu parameters for such combinated ISO (ubuntu-i386 and ubuntu-64) ???

BUT – have you tested using downloaded ubuntu.zip to your “super-ubuntu”.iso-file :O
Test and rename iso to UBUNTU.ISO.
Use CAPS to name= BIG LETTERS and copy ISO-file to the root= folder disk1 in EasyBoot

Or do this instead:
If I where you I should instead use separate ISO-files and make a copy of extracted ubuntu.ima  (extracted from ubuntu.zip) and rename copy of ubuntu.ima to ubuntu64.ima.
Extract menu.lst and modify parameters (name) to ubuntu64.iso-file

This is how “my” created original “menu.lst” from download looks like:

find --set-root /UBUNTU.ISO
map /UBUNTU.ISO (0xff)
map --hook
root (0xff)
kernel /casper/vmlinuz file=/cdrom/preseed/ubuntu.seed boot=casper iso-scan/filename=/UBUNTU.ISO --
initrd /casper/initrd.lz
boot

You can change name to this:

find --set-root /UBUNTU64.ISO
map /UBUNTU64.ISO (0xff)
map --hook
root (0xff)
kernel /casper/vmlinuz file=/cdrom/preseed/ubuntu.seed boot=casper iso-scan/filename=/UBUNTU64.ISO --
initrd /casper/initrd.lz
boot

you of course must rename ubuntu64.iso-file to exactly: UBUNTU64.ISO (you also must use CAPS to name= BIG LETTERS and have it copied to the root= folder disk1 in EasyBoot)

Attention! You don’t need to compress ubuntu.ima each time you test new menu-lines in text-file “menu.lst” inside ubuntu.ima, you can use floppy image as it is (not compressing) and still use menu command in EasyBoot:  memdisk ubuntu.ima  (instead of memdisk ubuntu.ima.gz).
And for modified menu.lst (modified to launch UBUNTU64.ISO) you use:  memdisk ubuntu64.ima

Note: The point with using memdisk instead of “run” is to avoiding the need to check “Allow lower case” and memdisk-command can also launch compressed floppy images :)

Thank you, that worked flawlessly. And with that ends my quest for the perfect rescue DVD.

I am not going to bother you anymore. at least for a while :)
