Hi Newbie here. I had a lightning strike which fried the motherboard of my 80gb PS3. I purchased a replacement board off of e-bay same 80gb board. I installed it moved the drives over from the old system and started it up. It asked me to re-format the old drive and I did..I did not do a backup since the old system was not working. I thought the o/s would be installed by the motherboard. It is now asking me to insert a disk that has version 2.70 or later operating system. Where do I get the o/s. I tried downloading 3.01 from the Sony site and installing the upgrade but it tells me that it is the wrong version.  Am I SOL or can I get through this problem? Any help would be greatly appreciated
