How to use that "amd dual core hotfix"?

i've read the faq for noobs for installing and running PCSX2 and give it a shot..

i have a game and all of the necessary emulators and plugins..

i tried to run it and it worked in a slow but manageable situation..

since that i'm using x2 core from AMD, the author of the faq said that "i have to use a dual core hotfix if im using a AMD Processor"

the author give the site.. but when i looked up in the site, i don't even have an idea on how to locate and install these dual core hotfix program..

i'm just giving it a shot and it worked so im quite interested in this one.. and i could manage to play the game even it's quite slowish..

maybe you guys here can help me about this "dual core hotfix".

tnx in advance!
