> THEY ARE BAD DOWNLOADS
bad downloads can easily be proved with qemu:
qemu -cdrom the-first-boot-disk.iso -boot d
if that boots, then it isn't the download.
if that works, you can eliminate it being the cd's you're burning with
qemu -cdrom /dev/cdrom -boot d
nb: replace /dev/cdrom with whatever is appropriate
if you don't have qemu, then:
wget http://fabrice.bellard.free.fr/qemu/qemu-0.7.0.tar.gz
tar zxvf qemu-0.7.0.tar.gz
cd qemu-0.7.0
./configure
make
make install
(ironically, these compilation instructions won't work on fc4t[1-3],
you'll have to use the older (supplied) version of gcc)
