Messiah question

I don't know much about the messiah mod chip all i know is that it is less of a hassle to boot so i got it.. but that has nothing to do with my questions.

I am wondering if it is a side effect of installing the modchip that i cannot set the time or the date on my ps2 or is cause something messed up during the installation.

Thanks for any help you can give me

1.If is v4 then connect the battery plug ( green plug )
2.If is v5-7 clean all solder points in cd/dvd controler to remove fluxes and solder bals.
Also check the battery condition

yhea check the battery

ok thanks so there is a problem with the mod then..
i got it done by someone else and they said that i have 2 months warranty from them so i am gonna take it to them to fix it..
just wanted to make sure they wouldn't say it is suppose to be like that and i would be left clueless..
thanks again
