199w ago - Hi guys, I used an Atmega8 running at 16Mhz (I had a couple lying about from the BT Vision project I was working on) and knocked up a small prog to do the same as the other chips and dump out the PS3 Hypervisor and Bootloader.
I was quite surprised, It actually worked fairly straight away! I only had one pulse going everytime I pressed the button at first but not a lot was happening.
So I did what xorloser did, and modded it so it pulsed every 100ms while the switch is pressed.
After about 30-40 seconds... I got a hit with the exploit code posted here. Then I used the dumper (posted here) to dump the 10mb bin.
Just having a look through the dump, lots of strings in there.. I haven't dropped it into IDA yet tho...
This is the source and hex (for those who dont want to compile it) for the Atmega8 which I glitched my PS3 with. The Chip I used was the Atmega8-16pu. You will also need a 16mhz Crystal, and 2 x 22pf Capacitors.
Grounding pin 14 on the chip will produce a pulse on Pins 2 of the chip (infact it does all of PORTD) This should then go to the memory bus point on the ps3. See Circuit diagram (below).
I used ponyprog to program my chip, with CKOPT ticked in the fuse settings, everything else was unticked.

personally, i think it would be priceless to use a mac keyboard and exploit, disable one of the led's (oh.. scroll lock num lock caps, take yer pick..] .. have modify the exploit code so that you have to type in glitchitnow [and hit say scroll lock -led you disabled] .. and away goes your 40ns pulses .. until say release key, and, also have the benfit of useing the keyboard on the ps3 to boot' instead of 1 usb connection, be additonal one .. one hack for another..
so.. who's up to do this one.. [personally i think GeoHot should, just to give the finishing touches on what he started] anyone for bets on the ramifications news wise on that one? lol...
IsoMick, How did you route the connection from the system board out of the ps3?
I have tried 3 different routes and everytime I tru to boot I get either a blacnk screen or an alert 0 and then hang.
If I remove the wire from the resistor it boots just fine. This drives me nut !!!
A picture wouldn't hurt if you have one.
