Both installing via net or CD needs bootstrapping with floppy disks. In this chapter we will learn where to get floppy images, and how to make useable boot floppies from them.
First we need a boot floppy. This will be a custom compiled Linux kernel image able to boot on the 7248. Then we need one or more ramdisk images.
For Debian, we need a boot floppy and one ramdisk floppy. You can download necessary files from http://users.linpro.no/ingvar/43p/images/Debian/ . The files are called debian-7248-boot.img and debian-7248-ramdisk.img . (The ramdisk image is the root.bin from Debian boot-floppies)
Yellow Dog Dayton
For Yellow Dog we need a boot floppy, and no less than three ramdisk floppies, because of the size of the installer. I have built custom ramdisk images for the 7248. The files are called ydl-7248-boot.img, ydl-7248-ramdisk-1.img, ydl-7248-ramdisk-2.img and ydl-7248-ramdisk-3.img, and are available from http://users.linpro.no/ingvar/43p/images/YellowDog/. You will need all the ramdisk files.
For SuSE, we need a boot floppy and one ramdisk floppy. You can download necessary files from http://users.linpro.no/ingvar/43p/images/SuSE/ . The files are called suse-7248-boot.img and suse-7248-ramdisk.img. (The latter is copied from ftp.suse.com)
For Mandrake, we need a boot floppy and one ramdisk floppy. You can download necessary files from http://users.linpro.no/ingvar/43p/images/Mandrake/ . The files are called mdk-7248-boot.img and mdk-7248-ramdisk.img. (The latter is a copy of the all-r6sk.gz from the Mandrake cd)
If you use Netscape or another web browser to download the files, you should check that the sizes of the downloaded files are correct. Some versions of Netscape tend to uncompress compressed files, and we want to keep them compressed. If strange things things happen at boot time, try using another program for downloading the files, like wget or lynx.
Use always errorfree 1.44MB floppies for these images. The commands shown here is for a working Linux system. They might work on other UNIX systems as well. On some systems you may have to be root to write directly to the floppy drive. In those cases, so du a 'su root' before issuing the commands.
To make the boot floppy, insert a floppy in the drive, cd to the directory containing the boot floppy image and issue the following command, substitute "debian" to your distributon prefix if necessary.
dd if=debian-7248-boot.img of=/dev/fd0 bs=36b
To make a ramdisk floppy, insert a floppy in the drive, cd to the directory containing the ramdisk image, and issue the following command. Substitute the filename with an image for your distribution of choice, like "ydl-7248-ramdisk-2.img" for the second YellowDog ramdisk floppy image.
dd if=debian-7248-ramdisk.img of=/dev/fd0 bs=36b
