You would need a main boot loader then from there you would have to put your distros in "folders" and have the bootloader "point" to each boot image within each folder. Or something like that. I use the nt bootloader on one of my computers to multiboot and when I add a system, I just install the bootloader for that os to that partition and then copy the boot.img to the place where the nt bootloader lives. ie.: windows lives on "c:\" and I install my linux /boot partition on /dev/hda6. I also install lilo to /dev/hda6 and after my system is installed, I use my boot floppy (or rescue cd) to boot into my linux I just installed and as root dd if=/dev/hda6 of=bootsect.lnx bs=512 count=1 I then mv the bootsect.lnx to my "c:\" drive and edit my boot.ini. Now, you can have as many of these images as you like (actually, I'm sure there is a limit - I just don't know what it is). I think the first thing I would begin with would be to test lilo to see if it will except paths from the cdrom. boot=/dev/hdc map=/boot/map install=/boot/boot.b vga=normal default=Linux keytable=/boot/us.klt lba32 prompt timeout=20 message=/boot/message menu-scheme=wb:bw:wb:bw image=/boot/folder1/vmlinuz label=My funky Linux root=/dev/hdc/folder1 initrd=/boot/folder1/initrd.img append=" hdd=ide-scsi hde=ide-floppy devfs=mount mem=1024M" read-only image=/boot/folder2/vmlinuz label=My other funky Linux root=/dev/hdc/folder2 initrd=/boot/folder2/initrd.img append=" hdd=ide-scsi hde=ide-floppy devfs=mount mem=1024M" That's just a possibility, I don't know if it would work.

You want to be able to choose one of several floppy boot images on a CD, on the fly, and boot from any one of them? ICBW but I don't think that's possible. Reading the eltorito spec leaves me with the impression that things are of very specific sizes and in very specific places on a CD to make it bootable. You'd only be able have one actual boot image on the CD. Whether or not you could then hack that image to continue booting in any one of several different paths I don't know. While there are probably those out there that could pull that kind of programming off, I'm not one of them. -- Mike Rambo [EMAIL PROTECTED] Want to buy your Pack or Services from MandrakeSoft?

The floppy image is created using dd (dd if=/dev/fd0 of=whatever.you.want.img) from whatever boot floppy I happen to need at the time. The hard drive images are created by setting up one computer how we want it and using ImageCast to create the image. Norton Ghost will do the same thing. You have to keep in mind though the we're just working with Windows boxes in classrooms and offices. I don't know if either ImageCast or Norton Ghost support any of the various Linux partitions (which is what it sounds like you want to do). -- Mike Rambo [EMAIL PROTECTED] Want to buy your Pack or Services from MandrakeSoft?

I had just figured this out when your email came through. I had tried to set it aside for awhile until someone told me what I was doing wrong but it drove me crazy with it sitting on the floor so I had to pull it back up and figure it out. Basically the key was that the boot image has to be in the same directory as the rest of the stuff that was recorded on the CD. I don't believe I had to do this on my old 7.1 box with kisocd - that package must have handled all that stuff in the background. In any case, it's all working now.

[expert] bootable CD
Maybe I'm just dense but how the heck do you create a bootable CD these days. I'm need to make a bootable restore CD for our public safety department. I want to put their computer hard drive image on it and have it boot from the CD and start imaging automatically. I have the hard drive image file. I have the boot floppy image. I can't get it all onto a CD successfully. I now have two coasters which have a perfect copy of the hard drive image file but the stinking CD's won't boot. The computer boots from other CD's just fine. I'm using a 8.1 system now and have tried xcdroast, eroaster, gcombust, and mkisofs from the CLI to no avail. All of them complain that they can't find either the boot image or the boot.catalog file. I have tried placing the floppy image everywhere I can think of and it has permissions that would allow everyone from Charles Manson to the Pope to read it. This is frustrating because my old system (7.1) with kisocd just worked by giving it a file name and location. Unfortunately kisocd is no longer supported it would appear. README.eltorito says that the boot.catalog file will be automatically created but doesn't say where. It also speaks of the boot image but doesn't say where it needs to be. Absolute paths don't find it which is totally confusing. The CD-writing howto on LDP just points to the README.eltorito file included with mkisofs. What is the magic step here to make this work?

[expert] Bootable CD
I was wondering about making a bootable CD on which I have built a preconfigured firewall.. ip masque / ip chains etc.. are there any ideas pro or con on this one ? it would be virtually hacker proof, and could chron to reboot at times to undo any damaged attempted to it am I way off base here ??
