Multiple potato images

Hey All -

I've built a test image to mess with, but am having a small problem :(  The
CD boots fine using Gary Tong's diskemu.bin loader (see below), and it loads
up several tools diskette images nicely.  It also is able to load the
various 2.88 boot kernel images just fine.  That is, up to the boot: prompt.

The problem comes with actually loading the kernel from the diskette image -
that's where it fails.  It gives a

Boot failed: please change disks and press a key to continue.

I have a feeling that syslinux is trying to talk right to the floppy, which
should be getting redirected to the ramdisk image.  That redirection must be
missing something.  Oddly enough, a bootable CD using just the normal 2.88
rescue.bin image as the bootable image works fine.

If anyone want to take a look, you can grab a 46meg ISO at


The information and software I've used can be found at :

http://www.geocities.com/iopat/	GT's Odds 'n' Ends

I like the idea of the scsitools diskette being available.  I'm sure we can
come up with a few other neato-keen tools to have available.  

The final result of what I'm looking to build is a 185meg image that can do
it all :)  Boot to any of the install images, boot tools images (a la Bart's
scsitools), a live system like Timo's Rescue CD
http://rescuecd.sourceforge.net/  That would fit on a mini-CD.  A 46meg
image would go on a business card CD like the Linuxcare BBC
http://open-projects.linuxcare.com/BBC/ among others.

Any comments on this yet ?  

The more I think of it, the more I like the idea of multiple kernels
available on CD1.  Maybe it's a minor point, but just having one decision
(which kernel to choose) is better IMHO than figuring out which CD to boot
from, then switching CDs etc.  Even then, the diskemu.bin booter can default
to the mainline boot kernel.

Gary's system works by booting diskemu.bin as a floppy image.  That then
scans the standard multiboot catalog on the CD for other floppy images,
presents a menu and boots the selected one.

This wouldn't be Debian only code - it's OS-independent assembler.
diskemu.bin is a utility that will boot *any* floppy images we want.  I
haven't done it yet, but it appears to be just a matter of defining the
various floppy images we want in the list.  We could add various "tools"
floppies as well for that matter.  Even <shudder> DOS based tools :)

Check it out - his info page is at
http://www.geocities.com/iopat/diskemu.html and he says it will go open
source.  Sounds like he wouldn't mind it being used in this case.

Well, if we wanted this, we should use grub, rather than writing a
debian-only version.

I hate debian-only code for it's own sake, AKA "NIH".
