I recently bought a used ps2 (ntsc version 7) and today i ordered a dms4 lite, i am planning on installing this myself, or getting my dad to do it. I'm no master solder guy, but i can solder like guitar cables and what not, will i have trouble and mess up my ps2, or is it easy and there is hope if i miss up a connection or something. i'm use to messing with computers and what not (not mother boards though) and i'm a fast learner.... also my dasd is an engineer, and i'm pretty sure he could do it, we have your typical old soldering iron, will that work fine, or do we need something else? what are your suggestions on the must haves and essentials for installing a chip. also, i read that after i install the dms4, i will have to do some 'flashing' does that just mean update the bios by loading a cd?
