How do you make he Duo3 support newer motherboard 7700?
How do you make he Duo3 support newer motherboard 7700? –
I got 2 of the new motherboarrd that are cooming out (GH051 from 7700 slim case). According to these diagrams they are suppose to work:
I have 2 of these systems and have tried 4 different Duo3 chips and the results are the same. The chip won't boot up the backups unless I put the game and then unplugg the power from the ps2, plug it back in and then boot the system with the game inside.
If I boot the system then put the game and try to launch the game it won't work (RSOD), if I boot the system put a game and then hit reset, then again RSOD. The only way to get the backup to work is by unplugging the power from the back of the PS2 plugging it back in and booting with a game inside.
i think the duo3 has poor boot rate on some of 7700X consoles. what you could try is to connect a 1k resistor across +5V and GND on the modchip , this might imporve the boot rate. or try a few different +5 point on the motherboard , this might also help. the ICE based chip has boot rate problem with certain motherboard across v14-v15. therefore installing a modbo745/750for v14-v15 as a cheap solution is not bad at all.
what speed did you set to burn your disc? discs burnt at fast speed could cause this kind of problem especially when they are played in slimline PS2's
i personally don't think modchip causes that unless it's overheating, but i don't think it's duo3.
all other ice based chips have DEV1 mode but duo3 does not. obviously they have modified the code. wondering if this could have some impact related to some weird issues. i have installed hundreds of messiah750, duo2 re-flashed with modified final ICE and never have such problem. i only experienced boot rate issue with some motherboards across v14-v15, exactly the same as a lot of people had with H2O in the past.
if you have a programmer, just re-flash the duo3 with the modified final ICE code and see if this solves the problem.
Unfortunately I don't have a programmer - so that's not an option.
I've tried a pile of discs - all which were probably burnt at 8x. I'll try burning another off at 1x and see if it helps.
Also, I've actually installed Duo3 into other v14s with the exact same mobos and never had an issue with those ones - so that's what REALLY has me baffled...
BTW - sorry to hijack your thread chalosf.
burning at 8x is absolutely no good mate ! i'm waiting for your result if you try 1x.
Just tried 1x Taiyo Yuden dvd-r (Final Fantasy XII) and the problem is still there. As soon as it loads, there is a cloud sequence FMV - this is where it'll stutter and then freeze.
Okay,... I feel like an idiot now...
It appears that all of my trouble was due to media issues (as I had originally figured). Here's the whole story...
A customer brought along a copy of Final Fantasy XII with his v14 PSTwo (he wanted to make sure that it worked with his machine after I modded it), and this is what kept stuttering & freezing. I'm pretty sure I had tried it in my v7 and it worked fine, but I tried it again tonight and it was doing the same thing as the v14 was. I had even re-burnt his disc onto a Taiyo Yuden dvd-r, but it didn't help. After reading somewhere, I think that maybe his copy is a PAL version - or there may be some copies leaked onto the internet that have this stuttering problem.
But the thing that really got me was that I have a backup of NHL2002 that was doing the exact same thing. I even tried re-burning my backup onto a Ridata cdr, but it didn't help. So tonight I decided to try re-burning NHL2002 from my original - and voila! it works perfectly. So somehow a flaw has developed in my original NHL2002 backup and I copied it when I tried reburning it.
So I went through a bunch of different dvd-r discs that I have and they all seem to work just fine. Just my luck that I'd have these two discs that I thought were fine all along...
Thanks for hijacking the thread on going on a different direction
Anyways my problem is not a bott rate issue, Duo3 chips work great, but with the new slims it seems you need to do something else to ge them to work because they are not enabling correctly
I haven't seen a 7700 yet, so I can't really help you out. But that is definitely one of the strangest boot sequences that I've ever heard of!
Did you try the 1k resistor like wmb88 mentioned? I know that helped with the H20 chips...
