But why settle for Fedora Core 6 when Fedora Core 7 for PS3 is right around the corner? dwmw2 on #cell (irc.oftc.net) convinced me to try out the development branch of FC7. Here's how you get it installed:
Update your PS3 (at least 1.60 or 1.70)
Download the latest otheros.bld that's built on petitboot and put it on a memory card in /ps3/otheros. Go to System Settings -> Install Other OS and install it.
Download the latest Fedora Core boot.iso and burn it to a DVD.
Reboot your PS3 in Other OS and select Linux64.
HD users: If you want to do the install in 1080i or 720p, wiggle the mouse on the Linux64/Linux32 selection screen and leave the mouse on Linux32. This will stop it from booting in 480i automatically. Then hit Ctrl-Alt-F1 to get to a TTY. From here, cd to /var/tmp/mnt-scd0*/ppc/ppc64 and run: '/sbin/kexec -f --initrd=ramdisk.image.gz --command-line="video=1080i" vmlinuz' (or video=720p) At the moment you can't just select "720p" or "1080i" from the graphical boot menu, as it does not pass video information on to the installer. :-(
When prompted for where to pull the install material from you can select HTTP, or you could just download it yourself and put it on a DVD which is much faster. Either way, the install material is here. If that's too slow you can try one of the mirrors, but beware -- the mirrors can be 1-2 days behind, which could cause you grief when you're pulling the latest from the development branch.
Observations after a day with FC7...
* I wouldn't recommend installing FC7 over HTTP! It took me 8 hours. The PS3 doesn't have enough RAM to manage the install very well.
* No sound in FC7
* No wireless in FC7
