Duo2 chip problem on V4,7, and 9.. Please help

[Bones4283]

Hey i have been installing xbox mod chips for a while and decided to brance out to PS2 chips. I bought Duo2 chips for the ps2's i have and followed the installation instruction pics i found on Divineo's help sections. Now i have a problem. When i boot the Ps2 the start up is diffrent. There is only one big "ball" at the browser screen then the rotating smaller "balls". This tells me that the mod chip is on and working because the Bios has been changed. Now when i go to test it with a game, i cant get the PS2 to read the dvd-r. I know this dvd-r works because it worked on a diffrent Ps2 console. I have checked and re-checked my points and dont know what is going on. I realy dont have a clue. Can someone please help me? Did i forget something or what?

Thanks

You probably could never tell if the chip is working by the 'ball'. From your post, the problem could be either installtion or laser. Try PS2 cd back up and PS1 game and see if it works. The laser is the problem if these game worked. otherwise check your installation.

This means your PS2 internal clock is stuck. Go into the clock adjustment menu and try to change it. It won't change. Keep trying, mash some buttons. Eventually it'll start again.

Every PS2 has a differently adjusted laser. I have many DVD-Rs (including an RW) that I could get my heavily tweaked console to read. No other console could read them. A few others read in some new consoles, but not in older ones, etc, etc.

If you are managing to get the console to boot, which you say you are, I'd probably go ahead and check if I actually hooked up power properly to the modchip!

Can you boot originals? If so, I'd almost certainly say it's something as "major" as that. If not, then you should check for continuity to all your controller wires (A-I + X/Y) from the modchip to the actual DVD controller chip itself (assuming you didn't solder there). If that's good, then check your BIOS wires (although, generally, if you mess those up, you won't get the console to start at all).
