HELP mod chip wanted

[D-RAT]

Here is the situation I have a brand new PS2 V5/V6 NTSC machine. I want to get a mod chip but my girlfriend paid for an extra 1 year warrenty when she bought the thing and I do not want to void a warrenty that I paid extra money for. What's the deal with the no solder mod chips? I hear they burn the laser or something like that.
