Thankx the_dude 

I heard that if your H1B is approved and you are not paid for a single day after Oct 1 except you had very good reason, then you would be out-of-status.

So, since My H1B is approved I cannot be in OPT from October 1 right???

And also about the payroll, do you guys have any idea what is the minimum amount to be run????

I am sorry I could not find the previous discussion about this OPT and H1 case. If anybody finds the thread then please post that thread too.
