orginally post by RealOne in General Emulation DUMPING YOUR BIOS THROUGH USB Things you need: USB mass storage device View attachment 130014 CD-R Modded PS2 (Else, A way to load up homebrew apps) Ok, let's start Step 1: Extraction Extract the DumpBios-USB.rar by using WinRAR Then, you will get the file DumpBios-USB.iso Step 2: Burning ISO to CD-R Burn the ISO file that you get from step 1 to CD-R Step 3: USB Mass Storage Device Your Flash Drive should : Have atleast +8MB Storage Space Be Formatted into FAT/32 Been allocated the Maximum Space Available. i.e, Have No partitions Step 4: Dumping Insert the Burned CD-R from Step 02 to your PS2 Insert the Flash Drive from Step 03 Start Your PS2 (P.S Only a modded PS2 could load a CR-RW) Now It should load up like the following Screen On that screen press SELECT On the Next Screen, The pointer should be pointed to Defaults, Just Press O. Note: This is an Important Step, Scroll Down to mass:/ and Select O. When You selected the mass:/ directory, it should go in to the device and should be able to be explored as in the following Screenshot. If you are not able to do so, you must check whether it has been formatted to FAT/32. If it is try changing the Flash Drive into the second USB hole. Now press X and go back. Browse to cdfs:/. This is the Directory of the Inserted disc. Inside the CDFS Directory you should have, DUMPBIOS-MASS.ELF. Select It and Press O Once You Have pressed O. You would have come to the Second Screen But slightly different Which you would notice. The DUMPBIOS-MASS.ELF would be selected in the Default Boot Now Press up twice, or a lot more times down and at the OK function press O. Now you should come up with this screen All you gotta do now is wait for 10 seconds and If you did it correctly Your Bios would be Dumped. Still Having Problems? You are bound to have problems on the first try. So, try again and make sure you havent missed out any step. Specially the one where you have to go to the mass:/ directory.
