The site here is where to get the Fedora Core 4 along with guides for installation.

The grub installer asks if there is more than one OS being run when you configure the
boot loader. When fat is detected it asks if you intent to install Fedora on that or the
ext #2 or ext #3. So far it has been tried on both of the extensions where Linux goes
to format those. The installation also asks for where you want the root.
There is an option to install a different boot loader in this version. Without reformat of
the 98 primary the third attempt will be to try the primary with the save information on
partition option. There isn't boot image file small enough for a floppy from what has been
understood so far. How do you get the loader into the MBR is another item. The loader
with this version can be modified by the third attempt.
