I'm bouncing this back to AD, sources say it orginated from AD:
here is what i found on Afterdawn.com forums....
Tonight CJPC had some freetime and decided to install Linux Fedora Core 5 (PPC iSO) along with PS3 Other OS Installer and the kboot from the CELL-Linux-CL_20061110-ADDON.iso file. Once installed (Installation Tutorial), he logged into the shell and dumped the Extended OS Area (which resulted in 4.0 MB (4,194,304 bytes) by using: dd if=/dev/sdb of=/extendedos.img
Next up, CJPC connected his external USB HDD to his PS3 (since he only has a 20GB stock PS3 HDD) and just (6) days after launch proceeded to dump (read "back-up" to $ony) his Madden NFL 07 PS3 Blu-ray Game Disc (the resulting iSO image is only 7.08 GB (7,597,719,552 bytes)) via the following: dd if=/dev/cdrom of=/mnt/exthdd/imagename.img
If you happen to own a 60GB PS3, you can use this command instead to dump directly to your PS3's HDD: dd if=/dev/cdrom of=/imagename.img
As we mentioned in our Past News, the PS3 Blu-ray Game Discs are currently not readable via Windows Blu-ray drive... however, the Blu-ray movies image fine on one of course. With that being said, the PS3 Blu-ray Game Discs resemble the PSP file format. See for yourself- here are the: Madden NFL 07 PS3 FileList.txt, Madden NFL 07 PS3 ICON0 pic, Madden NFL 07 PS3 PIC1 pic, Madden NFL 07 PS3 PARAM.SFO pic, Madden NFL 07 PS3LOGO.DAT pic, Madden NFL 07 PS3 USRDIR pic, Madden NFL 07 PS3 EBOOT.BIN pic, Madden NFL 07 PS3 Partial iSO Files pic, Madden NFL 07 PS3 TOC Size pic, and Madden NFL 07 PS3 UPDATE pic.
As many recall, the PSP scene began with Paradox dumping and releasing the first PSP UMD iSO images, followed by several other release groups and finally the first image lanchers to play them following shortly thereafter. How long will it take for PS3 iSO images to hit cyberspace? Time will tell, but after this Site News post it won't likely be long! Let the PS3 Game back-up experimenting begin guys!
Getting back to the topic, here are some additional pictures from Madden NFL 07 PS3 courtesy of CJPC: Madden NFL 07 PS3 pic, Madden NFL 07 PS3 DATA pic, Madden NFL 07 PS3_DISC.SFB pic, Madden NFL 07 PS3 EBOOT.BIN pic, and Madden NFL 07 PS3VOLUME pic.
In other exciting PS3 news today, Radiskull let us know of a new AdvanceMAME .106 Binary For PS3 released by Jurai.
