CD1 Lenny on usn pen

[abdelkader belahcene]

Hi,
I want to install debian from usb pen install of CD1.
Is it possible to put the CD1 ( the iso image par exemple ) on the USB pen,
I suppose that usb is bootable. The problem may occur in the path, since
from the cd, the installer searches packages in CD, how to redirect to the
usb.
any help is welcome
thanks a lot
