Download video: PS2 HDD-OSD (A new Softmod method!)
TIP: Right-click and select "Save link as.." to download video
Initializing link download.....
This method is a little more involved, but more rewarding in the end. Here's what you'll need;
1.) Fat model PS2 (sorry for you guys with the slim models)
2.) Original Network Adapter
3.) IDE/PATA HDD (any size will do, make sure it's compatible with PS2!)
4.) Some way to connect HDD to PC (IDE/USB Adapter or IDE ribbon on older PC)
-You can get one from here http://www.amazon.com/gp/product/B0018MCGVU/ref=oh_details_o00_s00_i00?ie=UTF8&psc=1
5.) Files (http://sdrv.ms/126rwOh)
I owe a lot of thanks to Leonard Olivaria for helping me with this. Without Leonard Oliveira (http://www.youtube.com/user/leonardoliveira) I wouldn't know this existed.
For now, you will have to use HDLoader and run it through uLaunch.elf to install games to the HDD, you can run them through OPL after you install them to the HDD.
