I need some help on my playstation3 system,i was trying to set up yellow dog on my ps3. I installed the boot loader and i just wanted to see what would happen if i just started the "other os" on my ps3, but the weird thing is linux just started loading without me putting in the installation dvd. I don't know if it was already put in or what, i have the 80gb ps3 so it was probably put in already. But when it was doing the installing, i know this is stupid but, i a was going to tell my bro about is when i accidentally tripped over the power cable and turned off my playstation wile it was setting up! so i plugged it back in and turned it on but now theres nothing coming up on the screen, also when i try to turn it off i, it wont, it beeps but the green light still stays on!! Can any1 help me plez, in need some advice!!!
