RSOD with MX bios/gh22 and m2 1.22

**bashy** · 05-02-2003,07:43 AM

No clue whats going on, Originals play fine DVD/CD backups all get RSOD..

BIOS
MXS023733
D110050
B10070

Gh-022

Im almost sure its a v7 and i've checked shorts and checked all other points for over an HR but the same thing. Starting to think that the chip might be bad!

Bump. I just installed a Magic 3.1 in a v7 and I get the same problem. I'm 98% sure it's not my media because the discs I use are very reflective and work perfectly in my Xbox. Is there a way to tell if the chip is even working or not? It's possible I damaged it because I had to use some desoldering braid to clean it up. That's the only thing I can think of. The 5V and ground are connected with thick wire.

do psx backups load? do dvdr movies of the same media type l oad? btw: i got a messiah2 last week that wouldn't boot anything..installed in 4 separate machines..so it is *possible* you have a bad chip..although i consider that the ultimate last resort explanation.

For me, PSX backups do not load, DVD-R movies (same media) work perfectly.

Is there a way to test the chip? Like, if I fed it 5V, could I use a multimeter to see if it's working or not?

I had the same issue with a v7 Gh-002 board using a dms chip. I ended up taking all the wires off and cleaning the bios pins. Re-installed the wires fresh and voila.... It worked!!! It was booting movies, ps1,devolution mode, Ps2 Cd/Dvd originals. It would not boot PS2 cd/dvd copies at all.

I just shortened all the wires and made sure the connections were all good.

Same thing. Backup movies work, backup games do not.

sorry to sound dumb but where is the cd/dvd dsp S #, which chip?

Did you check whether or not your chip is actually doing anything, ie try and boot a dvd movie or psx game without putting it into psx/dvd movie mode.

no movies psx or ps2 dvd/cd!! Only originals

Bashy, I think he was asking if pressed DVD movies or pressed original PSX games work when you boot it up normaly. Because if it does, then your chip obviously isn't doing anything. If it doesn't work, and it works only when you boot it in PSX mode, then your chip is operating, and your problem is probably the media your using.

In my case, DVD original movies, as well as DVD movie backups (so I know my media is good) work when it's booted up normally- just like it would if there is no chip. So the chip isn't doing anything. I'm going to shorten some more wires when I get home. I just read Charlie's guide on this and I didn't realize the ground wire needed to be so short (it's about 25cm right now).

What would make this much easier if there was a way we could test the chip on it's own (i.e. not having to put the PS2 back together so often). If I feed it power, would I be able to monitor any activity on any of the points with a multimeter?

Basically, I'm hoping that there's a way to see if the chip is dead w/o having to worry about the possibility of a bad installation.
