which messiah 2 chips need to get that track cut....

[batistuta7]

i installed a messiah 2 modchip in my version 7 ps2 and i know i did a good job. I read the guide for travelsooting the install guide all the way in the bottom. In the bottom it says that some messiah 2 modchips are difective and that to fix the problem you need to cut the track in the bottom of the chip. It says that these messiah's are the version 245 and below and i have a 243. Do you guys think i should cut that track or do you guys know where i can find a list of the messiah 2 versions that are defective?
thanks in advance!
