IMHO we can (and should) generate new rescue and driver disk images for

It is not very hard, once you have a kernel and a milo ...

Please put the config files up for ftp! This makes it much easier for a
volunteer effort to actually make something consistent... If you haven't
got the ftp space then I do, so then mail me a .tar.gz or something.

I have assembled, below, the instructions for making a rescue disk, as
discussed before on the list: notice that the rescue disk now also includes
It can easily be automated, and once workable config files exist for 2.0.34
then the complete operation is ~5mins per kernel on a machine such as mine,
provided the right milo is available, of course. That is just a question
of getting the newest milo for each architecture from gatekeeper and then
releasing with a note that the machines we have not actually tried to boot
are still in alpha installation-wise ...
It is really a shame that one cannot reload the rescue disk as a drivers
disk ... maybe a patch to boot-floppies to permit a type.txt containing
"rescue+drivers" or something?

Anyway, here is my proposal for how anyone can build a rescue disk from the
one on Loic's page or the copy in
CREATING A DEBIAN 2.0 RESCUE DISK FOR A PARTICULAR ALPHA VARIANT
Copyright (C) 1998 Kristoffer Rose

This text explains how to make a Debian 2.0 rescue for Alpha by manipulating
an existing disk image. This has the advantage that it can be done on a
non-debian Linux system even without using any floppies!
1. Make sure your kernel has the `loop' and `msdos' file systems in it. (If
they are modules then load them now.)
2. Locate (or compile) the `milo' file and the kernel that you wish to go in
the disk image, say it is called `vmlinux.gz' and has modules in
`lib/modules/2.0.34' (if there are no modules then create an empty module
directory with the appropriate name). Prepare a modules archive with the
# tar -cz -fmodules.tgz lib/modules/2.0.34
3. Make a copy of an existing rescue disk image onto, say, `/tmp/resc1440'.
If you already had it as a file then use `cp'; if you had it as a real
floppy then `dd if=/dev/fd0 bs=90k of=/tmp/resc1440' should do it.
4. Mount the copied rescue image as a file system with
# mount /tmp/resc1440.bin /mnt -t msdos -o loop
Now you can look at the contents of the disk.
5. Copy the desired kernel and modules onto the disk image.
# cp milo /mnt/milo
# cp vmlinux.gz /mnt/vmlinux.gz
# cp modules.tgz /mnt/modules.tgz
(using the kernel and modules from step 2).
6. Unmount the disk image with
# umount /mnt
7. Make the new image available for ftp and post a message to
a. the ftp address of the created resc1440.bin image, and
b. the .config file with which the kernel was generated (if known).
Then maybe we can put together an archive, making debian useful on as
many alpha variants as possible...
The above procedure will only make the disk bootable for ARC/AlphaBIOS based
systems. I don't know whether such a disk will boot off an SRM based system
(what digital calls a "unix" system, sic :).
You also have to use a drv1440.bin disk: for the moment any one will do, just
be sure to not install any drivers when asked (as far as I know this is not
used yet on Alpha because most of the used bootstrap kernels by Jay Estabrook
at digital have no modules anyway).
