Minimal installation images are available. boot.iso should be enough to get you going. You should be able to find it on most fedora mirrors. The one I just downloaded was only 147 megabytes.
The default grub menu gives you the options to install or upgrade an existing system, rescue an existing system, boot from the local drive, or run a memtest. There’s also the option for installing with basic video driver. This adds the boot options xdriver=vesa and nomodeset
This one (F10-x86_64) also gives me the option of using ext4 file systems while installing. This won’t be a big deal in future releases, but the regular release of Fedora 10 did not include this feature!
You will notice, however, there’s an extra dialog window presented that lets you know you’re using a developmental release. Don’t be surprised when you find little changes here and there, especially with the descriptive explanations of installation options.
