[Wlug] booting off cd/floppy images

Hi All, I have an intersting problem. I have a device (my old iopener) with linux installed and freeBSD (i dual boot). Both installs are really out of date, and i want to re-install linux, but i don't have a cdrom drive, or floppy drive. I only have network connection. Is there a way to add an entry in lilo to boot off a CD image, or floppy image? If anyone sees another way to install linux, i'm all hears. Thanks, --brad
