Ati mach 64 2mb

[emcclariion]

What files hold the res info? The .bib?

[emcclariion]

I am using your bib and I can get the high res, but still a white pointer I am sure its driver related

[dhedberg]

Sounds like it. Upload your drivers and I'll try them on my TT.

[frank.lukas]

I test with a 4MB M64 32k, 64k, 24-bit and 32-bit and all works fine ...

Dan,

They are the drivers from ideks page, just search for Atari nova drivers.

Frank I will try your .bb, but i am starting to think the card has a issue, what issue is the question...any colour depth over 2 colours produced a white square...its a pain as you cannot see it when in a open window have wait till it goes over a icon

It will drive 1440x900 at 256 colour and do 800x600 at 24b etc so its producing the colour depths the memory will allow...I did notice at 24b the mouse pointer block was purple

[emcclariion]

Right I have done some digging

https://www.x.org/releases/X11R7.5/doc/ati.html
And it seems colour depths 256 and over use hardware drawn cursor and I think this is the issue, not sure how to make it software only?

[czietz]

Did you consider asking the current author of the Nova drivers?

[emcclariion]

...last time I chatted he said he was busy with other projects idek are you there?

[dhedberg]

I can reproduce the problem with the mouse cursor (white block). It happens when I try to select a resolution requiring more than 2MB of Video RAM. Perhaps you have some faulty RAM chips on the card?

[frank.lukas]

May be test the card in a PC ISA Board under DOS and start the mach64 utilitiy test program.

[emcclariion]

Dan,

Interesting, it drives all the resolution's i would aspect for 2mb, 1024x768 at 64k, 800x600 at 24b and your custom 1440x900 at 256, which I would assume it would just crash if there was a memory issue, if i try to drive res i know will not work like 1024x768 at 24b you get like half a screen. also Dan it does not have a Ram card, would like one as 4mb would be great.



Frank, I dont have a I86 with ISA to test, I think I will retire the card for now and go back to my 32

[emcclariion]

All, I have been doing some more research and yes, the corrupted mouse pointer is due to all video memory being used.

I believe its a 2Mb, so not sure the reason as it happens in 800x600 in 256 colours which should be less than 1mb video memory.

but it depends on the driver setting how it fills up memory.

A work around would be to use sw mouse FAO Idek when you get time could you change the driver option to this.

Option "SWCursor" "true"

Has anyone gone a 2mb card for sale it would be interesting see what happens

[dhedberg]

I've got a 2MB card, not for sale, but which works well on higher resolutions, so most likely your card has some hardware fault. Are any of the RAM chips getting hotter than the others?

[emcclariion]

I will check tonight Dan, but I dont think it could be memory as it would have issues displaying 1024 x768 at 64k, but I do think there is a hardware issue

[dhedberg]

True, and you get absolutely no other corruption on the screen besides the mouse cursor, right?

[emcclariion]

Yes, its perfect no corruption at all if you are on the atari and Ste users facebook group..you will see my TT running mint and it looks Ace...

just the mouse pointer, I can use it but you cannot see the busy bee so you dont know things are working or not and it goes AWOL on whit backgrounds lol

[Rustynutt]

Forget if I'd asked. Did you try using Atari mouse hardware via the Atari connection?
That should tell if the soft driver is an issue with the card without IDEK having to modify the source.

[emcclariion]

Rusty,

Yes standard atari mouse

[Rustynutt]

Then do you think the software change will take care of the cursor blocking?
Y'all got me

[emcclariion]

yes, its due to the Match 64 doing hardware acceleration cursor/mouse pointer and there is some issue, so turning to only software should stop it

[stormy]

OK. Attached is a set of drivers and configurations. Copy it to your boot partition and try selecting the 1440x900 in 256 colors mode. It works fine on my Nova + Mach64 with 2MB (DRAM), I have note yet installed the new OGFA or made the hardware patches to restrict the VME address range on the Nova adapter.

Hey Daniel,
Just letting you know I'm very much enjoying your 1440x900 config! Was a bit difficult to sync with my display but eventually I found great settings for my Dell u2410, Pixel clock 52 Phase 3 gives me nice results.

Cheers

[dhedberg]

Glad it worked out well for you. The U2410 is an awesome monitor. I have 2 of them.
1440x900 is a perfect match when it comes to its native aspect ratio (1920x1200).

where did you find your 2mb module, im still looking, what part number do you have for it,

any change of a photo of the gfx card and the module ?

thanks

dave

[dhedberg]

I have a 2Mb Mach64 card but haven't found the 2Mb module for it yet.

[frank.lukas]

There are some Reseller in the US ...

Looking almost for the ATI numbers -> PN 109-26400-10

I buy mine taken from a PCI Card for 120 Canada Dollar + a lot of postage cost
