Pb installation AlphaServer 1000 / Floppy

["Philippe Navarre" <philippenavarre@wanadoo.fr>]

The context :
    Installing Debian GNU/Linux 2.2 For Alpha
    Chapter 7 Using dbootstrap for Initial System Configuration
    7.11 ``Install Operating System Kernel and Modules''
        If you're installing from floppies, you'll need to feed in the
Rescue Floppy (which is probably already in the drive), followed by the
Driver Floppies.

At this point, (atfter the loading of the rescue Floppy ), it say
    "the drivers are being installing from the first floppy drive. Please
insert driver disk 1"

I use the disk image : Driver Floppies :

http://http.us.debian.org/debian/dists/potato/main/disks-alpha/current/image
s-1.44/driver-1.bin

and I have the message "This is disk 1 of 2 in the drv14alpha_generic series
of 25-nov2000. Wrong disk. This is from series drv14alpha_generic.
you need disk 1 of series the driver series".

Thanks for help
