INSTALLING Games from ps3 HD to external HD? Easy! even the ps3break v 1.0 can do this task. You need to educate yourself in Game managers; ie. Open manager 2.1, Gaia, and Multimanager. All these managers will move games fron internal HD to external HD
1.Download any of the mentioned managers above to your computer.
3.Copy manager file to Usb stick/flash drive ect. (the drive must be formatted to fat32) to do this click computer, right click drive, chose format, then chose fat32.
You can just copy one of these managers to your external hard drive that you bought with the games on it, save you time because it is formatted already.
4.Once you have done that insert usb storage device (flas drive / ext. HD) into ps3.
5. start PS3 in Jailbreak mode.
6. Go to install pkg file folder, open and install.
7. Once you have a updated Game manager it will allow you to move games from ps3 to ext, HD and visa versa.
8. just chose a game already backed up and press O, it will ask you to move game to the opposite HD than where it currently is at.
As far as which board?? There are so many of those things floating around I would have to see a picture like mentioned on the post above me.
If it is copying and playing games DON"T MESS WITH IT! Don't fix what isnt broke. And if you are unsure as to what board/jailbreak you have upgrading payloads is going to either brick your Dongle or aggravate the hell out of you.
GOOD LUCK, hope this helps and If I deserve a +rep please don't hesitate!! Top right hand corner, (a little self promoting lol)
