Question about DMS4 Pro chip

[20cobra01]

I have been looking around the site and from what I can tell the Crystal or Matrix seem to be the prefered chip of choice. I may have jumped into the mod scene a little quick before doing my research. At any rate, I had ordered the solderless DMS4 Pro chip but the vendor said it was on back order so I went ahead and changed my order to the standard solder version. I started to feel as if I was getting the run around so I jumped ship and ordered a DUO2SE expecting that I had possibly been ripped off by the other vendor. Well after about 3 months the DMS 4 pro chip arrived, much to my suprise. I have been very happy with the DUO2SE and I am under the impresion if it aint broke then don't try to fix it, but I do have a few questions. I have not been able to find out much information on this chip outside of the vendor's website, and was wondering if anyone could clear some questions up for me. What does this chip offer over the DUO2. I believe it has upgradable BIOS since it has some on chip memory. Is this chip like the CC chip where you have to get updated bios in order to play back up games? Would this chip allow me to install a thrid party HDD (kind of serving in the place of HD loader?)? What other things would this chip allow me to do? Just trying to evaulate wether it would be worth going through unistalling my DUO2SE to install this DMS4Pro chip. Sorry for the long post.
