Hey PS2 PK. I have the same model, d430 1.33ghz. I kept getting boot errors until I read your fix. Thanks for getting that up there. I have had a heck of a time reinstalling snowleopard like 8 times trying to figure out what was going wrong. It should be stated that this is a fix for certain D430 models, because I can't reboot unless I have the EDP set to PS2PKs specifications. Thanks for helping, I love this forum by the way keep up the good work everyone! Also, any luck getting the trackpad at a better speed? Seems buggy.
