Make a directory and put the images into that directory....
mkdir /mnt/fedora
You need to mount the first image so you can make the boot floppy...
mount -o loop -t iso9660 yarrow-i386-disc1.iso /mnt/fedora
Make the boot floppy......
dd if=/mnt/fedora/images/bootdisk.img of=/dev/fd0 bs=1440k
Unmount the image....
umount /mnt/fedora
Reboot with the newly made boot disk and select the hard drive install from the hard drive using /mnt/fedora and the location of the iso images.
