9600: split screen on Tiger installation…

[superpantoufle]

Hi all,

Last week I conquered a PM 9600, which I plan to use as my main OldWorld machine instead of my 9500. It has 860 Mb of Ram and a 300 MMz G3 upgrade card, so I bet I could install 10.4 on it just for fun, using XPostFacto.

Everything went fine (grey Apple, verbose booting), until the installer window loaded: the screen is horizontally split in two. The upper part acts just as it should do: I can click on things, move around the windows, launch the utilities, etc. But it's not high enough for me to reach the OK button, which is below.

Then there is a 2-3 pixels black horizontal bar righ in the middle of the screen, and the lower half looks weird: same blue background, and an empty menu bar. When I try moving windows from the upper part to the right, assuming the lower part is a kind of "extended desktop", they do indeed appear in the lower part, but completely messed up, so I can only see mixed pixels and colors.

Has anybody seen something similar? I tried googling and searching the XPostFacto support forum, without any luck. But I don't know if I made myself clear nor if I'm using the right words…

Ok, it was related to the graphic card. I switched back to the original Twin Turbo, and it worked great.

had something like that as well with the original graphics card of a 9500

Exactly!

Now I tried with that card in the 9500 and in the 9600 with that same result. It's ok with the 9600's stock Twin Turbo, though. Interesting!

Thanks for the picture, it's much easier to see what I was trying to express!

My 9500's stock card was an ATI Mach 64 with 2 megs of Vram, how much does the Twin Turbo have? I'd guess this is the problem, not enough video RAM for OS X.

What card was behind the split-screen problem?

What card was behind the split-screen problem?

An ATI-something that I first found inside my 9500 when I got it. No model name is written on it (besides an ATI branded chip), and I didn't take time to google the model number.

But now everything's fine with the 9600's stock Twin Turbo (though both Panther and Tiger do fail during installation, but that's another story...).

HI,

I noticed in your pic of the 9600 that you've got a fan positioned near the PCI slots. On my 9600 there isn't a fan attached like this - but there is one in the side-panel that comes off... I'm guessing the rev'd the design at some point.

Interesting.

In Bolle's pic it's a 9500, with the same issue I had with my 9600. Look at the completely bare case, it doesn't at all look like the 9600!

Ah - I see it now - was just thinking it looked a bit smaller/thinner than the 9600. Oops!

cant be the VRAM i guess... the original iMac had only 2Megs as well and did work without a prb with OSX.

cant remember what card exactly was in there when i installed OSX. AFAIR it was some ATI card and i swapped it for a twin turbo afterwards which did work.
